Alphabetic Fern Catalog




















This Fern Catalog is a compilation of the information used on the information cards the San Diego Fern Society puts out to instruct the public about the various plants on display at the annual Fern Show. Each card attempts to list for each fern:

* the proper name (and, sometimes, synonyms),
* any common names (if known),
* a general idea of the areas in which it is found in nature,
* some general comments, including in many cases whether or not it grows well in San Diego,
* general climatic tolerance, and
* normal growing habitat (terrestrial, epiphytic, aquatic, xeric, etc.)

All of this must fit on a 3 1/2 x 5 1/2 inch card in large type, so it is necessarily brief. Added at the end of this information in this catalog (but not on the cards) are the Division and Class designation used for plants at the Fern Show. Because of the way we categorize plants for competition, these items tell a great deal about the growing habits and appearance of the plant. (See SDFS Division & Class Codes below.)

Should you acquire or own a fern for which you have an accurate name, the information included here should enable you to determine its growth habits and needs for planting, placement, watering, feeding, etc.

This list was constructed several years ago by first choosing all of the familiar listings in Barbara Joe Hoshizaki's Fern Growers Manual. Each year since then we have added descriptions for every new plant that has been entered in the Fern Show. We have used a wide variety of references to make these descriptions as accurate as possible, but you would be foolish indeed to believe they are perfect. Please let us know what you find to be wrong.

SDFS Division & Class Codes

For Classes in Division 1 through 18 the designations are all the same. They are as follows:

* Class A: Entire, lobed, other not class B, C, or D
* Class B: pinnate, pinnatifid
* Class C: Bi-pinnate/pinnatifid
* Class D: Multi-pinnate/pinnatifid

Division numbers specify the fern's size and manner of growth. Divisions 1 through 6 have mature fronds with lengths less than one foot, divisions 7 through 12 are mature fronds from 1 to 3 feet, and divisions 13 to 18 are mature fronds over three feet.

Within each group of divisions the descriptions are adapted from the code system used in the "Fern Growers Manual" but altered slightly for the current purpose. There are six Division definitions, each of which repeats three times, as follows:

Mature fronds
less than one foot Mature fronds
1 to 3 feet Mature fronds
over three feet
Wide creeping, fronds 2 inches or more apart DIVISION 1 DIVISION 7 DIVISION 13
Short creeping, fronds less than 2 inches apart DIVISION 2 DIVISION 8 DIVISION 14
Clump forming, rhizome branching DIVISION 3 DIVISION 9 DIVISION 15
Fronds in a close spiral, short erect, semi-erect or ascending stem DIVISION 4 DIVISION 10 DIVISION 16
Plant spreading by root buds, leaf buds, or stolons DIVISION 5 DIVISION 11 DIVISION 17
Tree fern or tree fern-like DIVISION 6 DIVISION 12 DIVISION 18

Divisions 19 through 21 are for Platyceriums only and are defined, for convenience, as follows:

* Division 19: Platycerium--Normal Care
o Class A: bifurcatum & cultivars
o Class B: willinckii, veitchii and their cultivars
* DIVISION 20: Platycerium-Normal Care
o Class A: Hillii and its cultivars
* DIVISION 21: Platycerium - Special Growing Care
o Class A: superbum
o Class B: grande, andinum, and holttumii
o Class C: coronarium, stemaria, elephantotis, alcicorne, wallichii, and ellisii
o Class D: ridleyi, madagascarense, and quadridichotimum

DIVISION 23 is for Fern Allies. The classes in that division are as follows

* Class A: Selaginella
* Class B: Lycopodium
* Class C: Others - Isoetes, Equisetum, and Psilotum


Acrostichum aureum
Swamp Fern. Worldwide tropics. A coarse fern with leathery, dark green fronds which forms large clumps in wet soils. Native to mangrove swamps and salt-water marshes in the Florida Keys. Often grows in brackish water. Large plants resent disturbance, small plants readily adapt. Require bright light and plenty of moisture. [Pantropical. Terrestrial] 16B

Acrostichum danaeifolium
Giant Leather Fern. Florida, Central and South America. This huge fern has fronds to over 12 ft. long. It lives in the swamps, either fresh or brackish, likes some sunshine and is quite sensitive to cold. The large, once pinnate fronds form a solid thicket. [Tropical to Semi-tropical, Terrestrial] 16B

Adiantopsis radiata
(No common name) Central America, S. America north of Brazil. Grows on damp shaded rocky slopes. Similar in appearance to Adiantum pedatum and A. hispidulum but the stipe is slightly flattened and has tiny longitudinal wings. Also, sori have true indusium. Grows erect to about 1 1/2 feet. Will need protection against low humidity to grow here. [Tropical to semi-tropical, Terrestrial] 9B

Adiantum aethiopicum
Common Maidenhair. Australia, New Zealand, Africa. Once thought to grow in Ethiopia, hence its name. It doesn't and is found in Africa only at the Southern tip. It is an average-sized Maidenhair with small fan-shaped pinnules. It likes light shade and wet soil where it will spread rapidly by wandering rhizomes. Its tolerance for sun and cold seems to depend on the origin of the plant or spores. Those from colder areas are quite hardy but those from tropical areas are not. Those sold in this area should grow easily if kept damp. [Temperate to Tropical; Terrestrial] 8C

Adiantum aleuticum
Western Maidenhair. Western Canada, Western U.S., Mexico. Very similar to A. pedatum, this fern is noted for its unusual stipe which branches with each branch turning out at right angles to the other, like a bird's foot. A hardy fern that thrives in cold districts, more difficult in hot climates. May be deciduous. Likes shady conditions and plenty of moisture. Grows best in the ground with a good covering of humus or mulch. [Temperate to semi-tropical; Terrestrial] 8C

Adiantum capillus-veneris
Venus Maidenhair Fern or Southern Maidenhair. Pantropical. A small delicate drooping fern with light green fronds. Most common in tropical zones. Often grows in limestone, in fairly sunny locations. Plants can be easily grown in pots fortified with lime or among rocks on the ground or on walls in a humid environment. Will not tolerate hot or drying winds. 'Banksianum', 'Fimbriatum' & 'Imbricatum' are popular cultivars. All grow well in Southern California. [Tropical to Temperate; Terrestrial] 8D

Adiantum caudatum
Walking Maidenhair. Africa, India, Asia, Indonesia. A fine maidenhair for basket or hanging pot. A small, tufted fern with long hairy fronds which root at the tips. Pendulous fronds with lobed segments. Can be grown between rocks in low to medium light and high humidity. Here it needs protection of a greenhouse or patio. Neutral to alkaline mix. Propagated by plantlets produced on the frond tips. [Tropical to semi-tropical, Terrestrial] 11B

Adiantum formosum
Black-stem Maidenhair. Australia and New Zealand. This is a truly beautiful maidenhair that grows to four feet tall in its native habitat. The fern forms extensive colonies by virtue of long-creeping underground rhizomes. The plant grows widely-spaced fronds in the ground but is more compact in a container. The Black-stem Maidenhair also grows well in a basket. These plants like an acid soil, particularly organically rich loam in a shady situation. Dislikes being disturbed. [Tropical to semi-tropical; Terrestrial] 8D

Adiantum hispidulum
Rosy Maidenhair. Five Finger Fern. Rough Maidenhair. Australia, New Zealand, Malaysia, S. India, Africa. This is a small fern with thin upright stems that are branched into three to seven fingers. During the growing season this fern will continue to rise, forming a dense stand of closely spaced scaly stems. New fronds are bright rosy pink. In its natural habitat this fern occurs in open forest on shaded earth banks or among rocks or other shrubs. Will grow well in all soils with good drainage provided. [Temperate to semi-tropical; Terrestrial] 8D

Adiantum pedatum
Five-fingered Maidenhair. American Maidenhair. Northern Maidenhair. Eastern US, Canada. Very similar to A. aleuticum this fern is noted for its unusual stipe which branches with each branch turning out at right angles to the other, like a bird's foot. A hardy fern that thrives in cold districts, more difficult in hot climates. May be deciduous. Likes shady conditions and plenty of moisture. Grows best in the ground with a good covering of humus or mulch. [Terrestrial] 8C

Adiantum peruvianum
Silver Dollar Maidenhair. South America. The new fronds are silvery pink with an almost metallic sheen. The pinnules (leaves) are roundish, reminiscent of a silver dollar. In the wild, the fronds get to be up to a yard long. Likes humidity and air movement, bright light. Here it is grown mostly in greenhouses. Allow soil to become slightly dry before watering. During the dormant winter period watering should be kept to a minimum. This fern is almost a weed in tropical situations, colonizing rocks and the mortar of buildings. [Tropical to semi-tropical; Terrestrial] 8C

Adiantum pubescens
(no common name) Australia, New Zealand, Sri Lanka, Fiji, New Caledonia. Very similar to A. hispidulum except the hairs of the latter are softer. Always has pedate (divided, with the divisions again divided) fronds. Forms an attractive clump of fronds. New growth is from brown to bright red. Very hardy. Likes an acid, organically rich well-drained soil. Likes a high humidity brightly-lit location, but no direct sun. [Tropical to semi-tropical; Terrestrial] 8D

Adiantum raddianum
Delta Maidenhair. Central and South America, Mexico, West Indies. This is the maidenhair fern from which most cultivated varieties arise, with no less than 70 variants known and named. It has great variability. In nature it grows in rocky outcrops, cliff faces, and moist stream banks. A majority of the forms like neutral to alkaline soil; need good drainage and fairly bright light. The species plant is seldom seen. [Tropical to semi-tropical; Terrestrial] 8D

Adiantum reniforme
(no common name) Africa, Canary Islands. This small fern has simple fronds, each with a single, thick, leathery lamina (blade) which resembles a Ginko leaf. The stipe, or stalk, is hairy. It is reputed to be hard to grow. It needs a very open, well-drained, mostly organic soil mix with an addition of lime. Small pieces of crushed limestone or shell-grit are beneficial. Terra cotta pots are also an aid to giving this fern good drainage and aeration of the root system. Prefers daytime temperatures of 60-80 degrees and cool nights. Will tolerate near zero temperatures. 3A

Adiantum tenerum
(No common name). Central and South America, Florida. This fern is found throughout tropical America but is seldom grown locally in the species form. It likes plenty of light and an alkaline soil. In the tropics it is frequently found in the mortar of old walls. A beautiful natural variety, 'Farleyense', grows well here. The cultivars 'Sleeping Ferguson' & 'Sleeping Beauty' are also grown but 'Sleeping Ferguson' needs a terrarium or greenhouse to do well. [Tropical to semi-tropical; Terrestrial] 2C

Adiantum trapeziforme
Giant Maidenhair Fern. Central and South America. This fern grows in tropical rain forests, mostly at low and medium altitudes, where it occurs on hillsides, stream banks, and sinkholes. The fronds on mature plants can grow to over seven feet in length with individual pinnules (leaves) over two inches long. The name is derived from the trapezoidal shape of the leaves. Requires protection if temperatures fall below 60 degrees. If possible, should be grown in the ground. [Tropical to semi-tropical; Terrestrial] 14D

Adiantum venustum
Evergreen Maidenhair. India, Canada. A most attractive fern from the mountain slopes of the Himalayas. Can also be found in Canada. It has large, erect, broadly triangular fronds with wedge-shaped toothed pinnules (leaves). The undersides of the pinnules are powdery on mature growth. Can be propagated from spore or by division from a parent plant. Young, actively growing rhizomes from spore grow better than divisions from an older plant. [Temperate to semi-tropical; Terrestrial] 7D

Aglaomorpha meyeniana
Bear's Paw Fern. Philippines. This is an epiphytic fern that grows as tall as 36 inches in its native habitat. It has an unusually large creeping rhizome covered with rust-colored scales. The thick scales hide the joint of the leaves with the rhizome. This species has glossy, dark green dimorphic leaves. The upper part of the fronds have ribbon-like fertile pinnae, about twice as long as the sterile segments. A rich, damp humus is preferred as a growing medium, with good ventilation and drainage. Likes a humid atmosphere. [Temperate to Tropical; Epiphytic] 8B

Aglaonaria robertsii 'Santa Rosa'
(no common name) This is an epiphytic fern with fronds up to four feet long. This is theorized to be a hybrid Aglaomorpha meyeniana and a Drynaria. The rhizome is covered with brown hair or scales. Can be grown in protected patio with medium to high humidity. Soil needs to be moist, but kept on the dry side. High light. [Tropical to semi-tropical; Epiphytic] 14B

Arachnoides aristata
Prickly Shield Fern. South East Asia, Polynesia, Australia. An attractive hardy fern which has triangular, glossy dark green, almost prickly fronds which grow to nearly three feet long and a creeping rhizome. It can be grown easily in a shady situation and will adapt to most well-drained soils. Once established, plants will tolerate periods of dryness. [Temperate to Tropical; Terrestrial] 8D

Arachniodes simplicior
Variegated Shield Fern. Japan and China. Sometimes sold incorrectly as Arachniodes aristata 'Variegata'. This is an attractive but slow-growing fern, popular with fern fanciers. It is notable for its glossy-green fronds that have a prominent yellowish band on each side of the midrib. Plants can be grown either in loamy soil or in a container. Grows well here. [Temperate to semi-tropical; Terrestrial] 8C

Arthropteris orientalis
(No common name). Africa, Asia. This is a monster fern with erect pinnatifid fronds to 6 or 7 feet long. Often found in granite outcrops. Dies down during the dry winters but should grow well here. (Semi-tropical; Terrestrial] 8B

Aspidotis californica
California Lace Fern. (Recently changed from Cheilanthes californica) From California and Mexico. This small rock fern has shiny dark stipes and fronds that have a broad outline. The fronds are deeply divided and lobed. It is evergreen, preferring dry situations. Plants are susceptible to over watering. It is happy in warm temperate climates and likes high light. Difficult to grow. [Temperate to semi-tropical; Xeric terrestrial] 3D

Aspidotis densa.
(no common name). British Columbia south to California and east to Montana. This is one of the so-called Cheilanthoids, the group of xerophytic ferns. It grows in the open on slopes and rocky outcrops, often on selenium (serpentine) substrates. [Temperate xeric; Terrestrial] 3D

Asplenium aethiopicum
Shredded Spleenwort. Africa, Australia, South India, Sri Lanka. It is a highly variable fern but its many forms have defied all efforts to define it more accurately. It is bi-pinnate and the secondary pinnules are tough and leathery, looking as though they had been cut off at the end with pinking shears. It is mostly epiphytic but also grows on various types of rock. It will grow well here in a small pot with loose mix or in a small basket. [Temperate to Tropical; Epiphytic or Epipetric] 10C

Asplenium antiguum
(no common name) Japan. A semi-hardy bird's nest fern that grows best in a protected patio. An epiphyte, it grows on trees and rocks in the wild, collecting debris in its leaves to use as food. Tightly arranged polished green fronds will sometimes fork at the ends. The fronds grow two to three feet long, and the crown turns whitish brown when mature. Likes humidity so keep soil constantly moist and use rich humus. No direct sun. 'Victoria is a popular cultivar. [Temperate to semi-tropical; Terrestrial] 10A

Asplenium australisicum
Bird's-Nest Fern. Australia, New Caledonia, Fiji, and Tahiti. The fern grows in the top hamper of tropical jungles and the fronds can get to be almost seven feet long. The midrib of each frond is gently rounded on top and sharply keeled on the bottom. See A. nidus. This is a very robust and strong-growing Bird's-nest type that adapts extremely well to cultivation. Can be grown in the garden on rocks or as a tub plant in a coarse mixture. Makes a good house plant. There are several cultivars, i.e. 'Cristata' & 'Fimbriata'. All of these are almost always sold locally as A. nidus, a similar but different species. [Tropical to Temperate; Epiphytic or Terrestrial] 16A

Asplenium billotii
(no common name) Europe. This small species with bright green fronds gets to be 12 inches at the most. Can be grown in a small pot of fibrous acid mix, or in a shady position outside. It will tolerate very cold climates (remaining green) but need continual protection against slugs and snails. [Temperate; Terrestrial] 4D

Asplenium bulbiferum
Mother Fern. Australia, New Zealand and Malaysia. A delicate green fern with fronds like carrot tops. Small plantlets appear on the top surface of the fronds that can easily grow new ferns. Likes low to medium light but will tolerate a little direct sun. Keep soil evenly moist with an occasional drying. [Temperate to semi-tropical; Terrestrial or Epiphytic] 11D

Asplenium ceterach
Rusty-Back Fern. India, Africa, Europe. This fern has also been known as Ceterach officinarum. This is a dwarf limestone loving fern eminently suitable for the rock garden. It has small, evergreen, deeply-lobed fronds, 3-6 inches long. The reverse side of the fronds is covered with silvery scales that become rusty brown. For every plant found on natural rock, a hundred will be found on old mortared walls. [Temperate; Terrestrial] 4B

Asplenium cuspidatum
(No common name). Mexico, Guatemala to Panama. This medium sized fern with highly divided fronds is part of what is known as the A. auritum complex, a complicated and confusing group of perhaps a dozen very similar ferns. It usually lives in the trees of Central America and should probably do well here. [Tropical to Semi-tropical; Epiphytic, Epipetric] 2D

Asplenium dalhousie
Countess Dalhousie's Spleenwort. North India, Mexico, Arizona. This fern is probably more frequently known as Ceterach dalhousie although it is also called Asplenium alternans or even Ceterachopsis dalhousie by botanists. This is a neat little fern that grows to be 2-6 inches tall. It forms a small rosette of dark green fronds. Can be grown here with care. [Temperate to semi-tropical; Terrestrial] 4B

Asplenium daucifolium
Mauritius Spleenwort. Mauritius and Madagascar. This is a handsome spleenwort with long, arching finely dissected fronds that are liberally sprinkled with plantlets in the manner of A. bulbiferum. It makes an excellent basket plant, but can be equally well grown in a dry, shady position in the ground where it will grow about 2 ft. Tall. [Tropical to semi-tropical; Terrestrial] 11D

Asplenium flaccidum
Weeping Spleenwort. Australia, New Zealand, Pacific Islands. This delightful fern is renowned for its strongly weeping and delicately lobed fronds. Epiphytic by nature it makes an excellent basket fern in a coarse, fibrous mixture. This plant can grow to be as large as 40 inches. Likes humid conditions with some air movement. Extremely variable in growth habit, with some forms having a few long slender fronds with the rest shorter and compact. It also grows as an upright terrestrial. [Temperate to semi-tropical, Epiphytic, Terrestrial] 10C

Asplenium goudeyi
(No common name) Australia. This is a close relative of A. australisicum, one of the common Bird's Nest ferns, and is endemic to Lord Howe Island, Australia. The fronds are shorter and more erect, gray-green rather than bright green and much more leathery. It is new in this area but so far seems to enjoy it here with the same treatment as A. australasicum and A. nidus. [Tropical to semi-tropical; Epiphytic, Epipetric.] 10A

Asplenium nidus
Birds-nest Fern. Pantropical. A large epiphyte which usually grows in the tree tops but can be easily grown in pots, tubs or among rocks in the garden. Grows to be about 5 feet tall. The midrib of each frond is raised and rounded on top, nearly smooth on the bottom. See A. australasicum. This fern is very seldom found here. Most plants sold under this name are, in fact, A. australasicum. One exception is A. nidus 'plicatum' which is usually known as the 'Lasagna Fern', a small, heavily twisted version of the Birds-nest. [Temperate to tropical; Epiphytic, Terrestrial] 16A

Asplenium oligophlebium
(No common name) Japan. This is a small graceful fern that spreads by rooting at the tips of its arching fronds. The fronds are pinnate with deeply incised pinnules and grow to about 12 inches long . In a shady spot with rich, loose soil it will make a good ground cover. [Temperate to semi-tropical; Terrestrial] 5B

Asplenium pinnatifidum
Lobed Spleenwort. Eastern U.S. This plant looks like a long-stemmed, more upright and deeply lobed Walking Fern, with the same long tapering and pointed leaves, but greener and more crinkled. This fern is usually found in rocky, inaccessible crevices of acid soil. The leaves are about 6 inches long, broadest at the base, and tapered to a point with a thick semi-erect lower half that is distinctly and deeply lobed. Evergreen. [Temperate; Terrestrial] 5B

Asplenium polydon
Weeping Spleenwort, Mare's-tail Fern. Australia, New Zealand, Asia, Pacific Islands. This handsome, widespread fern (also known Asplenium falcatum) is epiphytic throughout the tropics and sub-tropics although there is a terrestrial form on Lord Howe Island. It is once pinnate, growing from a short creeping rhizome. The most attractive form has long hanging fronds with toothed pinnules. It may need a little protection in the cooler parts of So. California. [Tropical to semi-tropical, epiphytic] 8B

Asplenium ruta-muraria
Wall-Rue Spleenwort. Europe, Asia and northern North America this dwarf fern ( 2" - 5") is nearly always found in rock crevices and in the limestone mortar of old walls. Dislikes pot culture, but does well in shady limestone scree. Very uncommon here. [Temperate; Terrestrial] 4C

Asplenium scolopendrium
Hart's Tongue Fern. Europe, Asia, Northeastern North America. This widespread fern grows on limestone or calcareous soils and on old mortared walls. It has a nest of simple fronds as much as 2 ft. long. Known to the British as 'Scollies' they are among the most popular ferns in cultivation. Hundreds of forms are known, some natural and some arising in cultivation. Known to some as Phyllitis scolopendrium. They have proven difficult to grow in Southern California. [Temperate; Terrestrial] 10A

Asplenium simplicifrons
Narrow-leaf Bird's-nest Fern. Australia. This is a very distinctive Asplenium that grows in moist, shady situations from lowland to highland regions. The plants form an attractive upright rosette of dark green, slender fronds to 24 in. An ideal pot or basket plant excellent for indoor decoration tolerating quite dark conditions and neglect. [Tropical to semi-tropical] 10A

Asplenium surrogatum
(No common name) Australia, New Zealand. This is a medium size terrestrial plant that is very similar to the epiphyte A. flaccidum. It is the plant that used to be known locally as A. mayii and may still be found for sale under that name. It has long bi-pinnate fronds with strongly serrated pinnules. [Temperate to semi to tropical; Terrestrial] 10C

Asplenium trichomanes
Maidenhair Spleenwort or Common Spleenwort. Worldwide. It is common throughout Britain and in the U.S. where it is found in the East and South to Georgia and Alabama and West to Alaska. Its native habitat is soil pockets in limestone rock, but it is tolerant of other soils, other rocks. Requires shade and moisture. Grows sometimes on undersides of rocks or in the mouth of a cave. Cultivars are 'Cristatum' and 'Incisum'. Difficult in Southern California. [Temperate; Terrestrial] 4B

Asplenosorus ebenoides
Scott's Spleenwort. Eastern U.S. This is a natural cross between Asplenium platyneuron with Camptosorus rhizophyllus. The highly variable fronds are evergreen, from 4-12 inches long. The fronds are highly variable, cut in bizarre patterns of assorted shaped and sized lobes. When the tip of the frond touches the ground it will sometimes root. Extremely difficult to winter over here is Southern California. [Temperate; Terrestrial] 5B

Astrolepis beitelii
(No common name) Central valley of Mexico. Until recently known as Cheilanthes beitelii this fern is part of the 'sinuata complex' the members of which are very difficult to distinguish. A. beitelii lacks the dense glandular hairs as well as the adaxial surface hairs of A. sinuata. Fronds grow to nearly 2 ft. long. It grows on dry rocky slopes in nearly full sun and will grow well here if given excellent drainage. [Semi-tropical, xeric; Terrestrial] 9C

Astrolepis sinuata
Wavy Cloak Fern. From North America, Mexico, Central America, and South America. This is one of many species forms that grow in hot and arid conditions in the Southwestern US. Some forms are greenish and some appear blue-tinted. This hardy fern usually grows in gravelly soils in sunny or shady conditions. Plants require excellent drainage, bright light, and good air circulation. Until recently these ferns were included in the genus Notholaena. Divided into three sub-species. [Temperate to semi-tropical, xeric; Terrestrial] 3C

Athyrium filix-femina
Lady Fern. United States, British Isles, Africa, India, China, Japan, Canada, Mexico, and Peru. There are said to be 40 native American forms and over 300 named forms altogether. This is a deciduous fern in cold areas and dormant during the winter. It grows best in the ground rather than in a container and requires a shady to semi-shady situation on loamy, humus-rich soil. All forms are difficult to grow in Southern California. [Temperate; Terrestrial] 10B

Athyrium niponicum
Japanese Painted Fern. Japan. This fern has unusual coloration with green and white pinnules (leaves) but is seldom seen in cultivation. The commonly seen variety is 'Pictum' whose veins, ribs, and stipe of deep burgundy. There are two common varieties of this plant. One is a tall growing deeply colored plant with fronds to 20 in. long. The other grows much shorter fronds but a greater number, giving a dense look to the foliage. The leaves and stems on the shorter variety tend to be much lighter colored, as well. Both are deciduous and hardy, except in extreme cold. [Tropical to semi-tropical; Terrestrial] 10B

Athyrium othophorum
(no common name) Japan, China, Korea. Grows to 20-28 inches tall. This fern has distinctive, fairly broad, deltoid fronds which have dark green segments and a reddish to purplish stipe and rachis (stem). Plants prefer a shady location in humus-rich loam. [Temperate to semi-tropical; Terrestrial] 10B


Belvisia mucronata
Needle Fern, Tailed Fern. Polynesia, Malaysia, Australia. This is a member of a seldom grown genus that is distinguished by having a long, slender, tailed section at the end of its fronds. This tail forms the fertile section of the frond and the sporangia form a pair of long lines protected by the reflexed portion of the frond. Makes a nice basket plant in sphagnum or a coarse soil mixture. [Tropical to semi-tropical; Epiphytic, Epipetric] 7A

Blechnum appendiculatum
Hammock Fern. West Indies, Mexico, and South America. Found in the local trade as Blechnum occidentale or B. glandulosum. A small form with constantly changing color of frond from pink to green during growth. Underside of stem is hairy. Makes a good ground cover under trees. Likes partial sun, food and water. [Tropical to semi-tropical; Terrestrial]

Blechnum australe
(no common name) From Africa, South America, and Madagascar. This is a small (20 inches) attractive Blechnum which forms clumps of dark green fronds on the ends of slender rhizomes. In cultivation this plant likes plenty of moisture and a semi-shady situation although it will tolerate exposure to a fair amount of sun. A useful ground cover fern. [Temperate to semi-tropical; Terrestrial] 9B

Blechnum brasiliense
Brazilian Tree Fern. This is not usually considered a true tree fern as its trunk rarely exceeds three feet in height, but fronds can be 2-5 feet in length. Largest of the Blechnum genus. Has a beautiful crisped cultivar, B. brasiliense 'Crispum' , which shows the red new growth typical of the Blechnums to great advantage. Both are easily grown here. [Tropical to semi-tropical; Terrestrial] 12B

Blechnum cordatum
(No common name) Guatemala to Panama. Also commonly known as B. scheideanum. This fern is very difficult to distinguish from B. falciforme differing primarily in the layering of the scales. It is a large fern that grows to perhaps 60 in high. It is dimorphic with the fertile pinnae highly contracted. Young growth is bright red. It grows on the drier eastern slopes that make it a good candidate to grow here. Keep it fairly dry with lots of light. [Tropical to semi-tropical, Terrestrial] 10B

Blechnum falciforme
(No common name) Guatemala to Panama. This is a large fern with fronds from 18 in. to perhaps 60 in. long. Depending on location. It is dimorphic, fronds being either sterile or fertile. The fertile pinnae are highly contracted. Young growth is bright red making it an interesting member of the garden. It grows on the drier eastern slopes of Central America, making it a good candidate to grow here. [Tropical to semi-tropical; Terrestrial] 10B

Blechnum gibbum
Dwarf Tree Fern. New Caledonia, New Hebrides, and Fiji. Grows to 28 inches like a miniature tree fern. Develops a short, stout trunk with age. This popular fern has an appealing crown of finely divided fronds. Plants are excellent for containers, but can also be grown in the ground in a shady, moist situation. Absolutely must be kept damp. [Tropical to Temperate; Terrestrial] 12B

Blechnum gracile
(No common name) Central and South America. This is a relatively small member of the B. occidentale complex with blades of the fronds up to about 10 in. In length but stipes (stems) anywhere from two to 10 inches long. . It colonizes rapidly by means of stolons. It grows along the banks of streams in the wet low altitude forests which means it likes water and light. Grows nicely here. Would make a good ground cover. [Tropical to semi-tropical; Terrestrial] 9B

Blechnum minus
Swamp kiokio. Australia, New Zealand. This fern is part of the B. capense complex and may not be a separate species. It is dimorphic with fronds forming a clump about 3 ft. high in the wild. If kept damp will stand nearly full sun and they grow well here. [Temperate to semi-tropical; Terrestrial] 17B

Blechnum moorei
(no common name) New Caledonia. This fern grows to be up to 32 inches tall. It grows much like Blechnum gibbum and, indeed, may be another form of that species but has much broader segments on the sterile fronds. It develops a short trunk as the plant matures. It is cold-sensitive and likes a warm, moist situation. [Tropical to semi-tropical; Terrestrial] 12B

Blechnum norfolkianum
(no common name) New Zealand. Found on the islands on the north shores of the North Island it is very similar to B. chambersii that is found on the mainland. This fern is larger with fronds well over three feet long, pinnatifid, with as many as 60 pinnule pairs. It likes it warm and dryish with a light rich soil. Should be very easy here. [Semi-tropical; Terrestrial] 18B???

Blechnum occidental
Hammock Fern. West Indies, Mexico, and South America. Very similar to Blechnum appendiculatum but underside of stem is smooth. A small form with constantly changing color of frond from pink to green during growth. Makes a good ground cover under trees but is seldom found in cultivation. Likes partial sun, food and water. [Tropical to semi-tropical; Terrestrial]

Blechnum penna-marina

Elaphoglossum genus
This genus of at least 600 species is seldom cultivated here, probably because most originate in the humid American tropics and require constant high humidity. Many species in cultivation are unnamed and there are probably even more undiscovered species still in the wild. They are characterized by simple, entire, usually leathery fronds. The sporangia cover the entire back of a fertile frond. Most are epiphytic although terrestrial forms are not unusual.

Elaphoglossum crinitum
Elephant Ear Fern. Tropical America, West Indies. This spectacular fern has simple fronds that appear like huge paddles up to 20 inches long. The frond is about half stipe and half lamina and all are covered with long black scales. Young fronds appear black because of the density of these scales that appear to thin out as the frond grows. Like all Elaphoglossums the back of each fertile frond is covered with sporangia. Requires a atmosphere of constant high humidity. [Tropical; Epiphytic]

Elaphoglossum peltatum X
(No common name) Also known as Peltapteris peltata. Southern Mexico; Guatemala to Panama. This small crawler is very common on mossy tree trunks and fallen logs in the hot humid tropics.

Can be grown here only in a terrarium or greenhouse. [Tropical; Epiphytic] 2A

Elaphoglossum vestitum
(no common name) Mexico. Elaphoglossums are seldom-cultivated ferns, probably because most originate in the humid tropics and can be tricky to grow, especially in Southern California's dry air. They are characterized by the sporangia that can cover the entire back of a fertile frond. This species originates in southern Mexico and must be well-drained, but the plant likes to stay moist. This particular species does well here. [Tropical to semi-tropical; Epiphytic] 8A


Goniophlebium subauriculatum

(No common name). North India, China, Malaysia, Australia, New Guinea. A very large fern from the tops of the tropical rainforests.

It is dimorphic and the petioles are lanceolate to linear, thick and shiny. It will tolerate a temperature range from 43? F to 84? F so it should grow here along the coast. A very well draining mix is recommended with plenty of air movement, humidity and light, but no sun. [Tropical or semi-tropical, Epiphytic] 3A


Lemmaphyllum microphyllum

Green Penny Fern. India, China, Japan, Korea, Taiwan. A small creeping epiphyte with small, thick, shiny, simple dimorphic fronds. The sterile fronds, from which it gets it common name, are rounded and fleshy while the fertile fronds are longer and fewer in number. It grows well on a tree fern slab or in a small basket and will cover the surface. Although highly tropical in appearance it is really quite temperature tolerant and grows very well here. [Tropical to temperate; Epiphytic] 2A

Llavea cordifolia
(no common name) Central America. This is the only species in the Llavea genus. Growing to over 2 feet long, the fronds are dimorphic with spore packets being developed in specialized finger-like segments at the ends of the mature fronds. Naturally occurs in exposed rocky situations, usually on limestone. Plants can be grown in the Southern California area, but have a dormant period during the winter when they should be kept on the dry side. An open neutral to alkaline mix is necessary. [Temperate to semi-tropical; Terrestrial] 10B

Lophosoria quadripinnata
(No common name) Central and South America. The only species in the genus is a primitive tree fern. Above ground it is somewhat similar to the Dicksonias except for the large fronds which are glaucus (grayish) on the underside and the sori have no indusium. Below ground the rhizomes are quite different. It lives in the high montane forests in tropical America and seems to be happy here. [Tropical to semi-tropical; Terrestrial]

Lygodium japonicum

The stems reach to the surface and produce four-lobed pinnules with a distinctive brown band. They grow well here and make good ornamental covering for fish ponds. [Tropical to semi-tropical; Aquatic] 8A

Marsilea quadrifolia
Water Clover, Water Shamrock. Europe, North America, China, Japan, Korea. These plants typically grow in ponds or along the sides of streams. They root in the mud at the bottom and send up stipes, or stems, perhaps two feet long, to the surface. The floating blade is usually made up of four pinnules and looks like a clover leaf. The sporangia are encased in sporocarps, a hard shelled husk at the base of the pinnules. [Temperate to semi-tropical, Aquatic] 8A

Matteuccia orientalis
(No common name) China, Japan, Korea. This plant is about half the size of its cousin Matteuccia struthiopteris and is quite uncommon here. The fertile fronds are upright to about 3 ft. while the sterile fronds lie nearly flat on the ground. It needs wet, soft, loamy soil and will spread by underground rhizomes. [Temperate, Terrestrial 17B

[Temperate, Terrestrial] 17B

Microgramma lycopodioides
(No common name) Mexico, Central and South America. This fern tends to cover trees with creeping masses of bright green fronds to about 8 in. In length. The slender rhizomes branch freely and are covered with rusty brown scales. Likes it warm, moist and airy but will grow outside here if protected from extra dry air. [Tropical to semi-tropical; Epiphytic] 2A

Microgramma squamulosa
(No common name) Brazil. This fern has been known until recently as Polypodium squamulosum. It is native to Brazil but was introduced into England in 1846. It is a small epiphyte with a frequently branching rhizome and simple fronds to about 3 inches in length. The sterile fronds make a beautiful display with a prominent vein pattern that almost makes them look pinnate. It must be protected from low temperatures and therefor usually must be grown in a terrarium or greenhouse where it makes a beautiful basket plant.. It can be grown outside here in protected areas. [Tropical to semi-tropical; Epiphytic] 2A

Microgramma vaccinifolia
(No common name) South America. This fern has been known until recently as Polypodium vaccinifolium. This little crawler is dimorphic with simple fronds to about 4 inches long.

It is a clumping fern that can be used to shelter smaller species. It likes shade in a well-drained, loamy soil. [Tropical to semi-tropical; Terrestrial] 15D

Microlepia speluncae
(No common name) Pantropical. This fern has huge arching fronds to 5 ft. In length. It grows is semi-exposed locations along the edges of forests, road banks, etc. It should grow well here but is seldom seen, perhaps because of its size. [Temperate to tropical; Terrestrial] 9D

Microlepia strigosa
Lace Fern. Tropical Asia, Micronesia. A thick-growing terrestrial fern that grows to about 40 inches tall. The fronds are much divided and lacy looking, hence the common name. Despite its tropical origin it grows well here and will make thick background coverage. It also makes good greenery for flower arrangements. Technically, the plant usually sold and grown here is M. pseudo-strigosa but the differences are very slight. [Tropical to semi-tropical; Terrestrial] 9D

Microsorum linguiforme
(No common name) Borneo, Philippines, New Guinea, Fiji. This is an epiphyte with erect, dark green, thin textured fronds to about 20 in. In length. They serve to trap litter which rots down to provide food for the plant. May be grown in a basket with coarse soil. Needs greenhouse protection here in Southern California. [Tropical to semi-tropical; Epiphyte] 8A

Microsorum muscifolium
(No common name) Malaysia, Philippines, Indonesia, New Guinea. This fern was earlier known as Polypodium muscifolium. It is very large for a tree climber with a wide creeping rhizome and simple fronds to about 3 ft. In length. The fronds are thin and the vein pattern is prominent. Although this fern is listed a being semi-tropical it is probably on the border of being growable unprotected in this area. Should grow easily in a humidity enclosure. [Tropical to semi-tropical; Epiphytic] 7A

Microsorum normale
(no common name) North India, South China, Malaysia, New Guinea, and Australia. This fern has thinly-textured, strap-shaped fronds up to 16 in. long which end in a short point.

Microsorum steerei
(No common name) Vietnam, South China, Taiwan. This is a medium sized, short creeping epiphyte with thick rhizomes and fairly heavy fronds from 12 to 16 inches long. It should be grown in a basket or tree-fern pot and is probably borderline to grow outdoors here. [Tropical to semi-tropical; Epiphytic] 9A

Microsorum vieillardii
Kangaroo Fern. New Caledonia. This fern is very similar to M. diversifolium and M. scolopendrium but its single row of sunken sori are very close to the margin of the pinnule. Its long fat rhizomes scramble on the ground and up trees. Although this group is common throughout the tropics they are hardy enough to grow easily here. [Tropical to semi-tropical, Terrestrial] 7B


Nephrolepis biserrata

Coarse Sword Fern. Pantropical. This is a large, coarse fern that grows fronds to over 8 feet long. It can be grown easily as a garden plant or in a pot. In the ground, the plant tends to be invasive. Can stand considerable sun when grown close to the coast. Seldom seen here. [Tropical to semi-tropical; Terrestrial, Epiphytic] 11B

Nephrolepis cordifolia
Sword Fern, Fishbone Fern. Pantropical. This fern will grow almost anywhere, in trees, on rocks or in the ground and in nearly any tropical or temperate climate and will take full sun. Although it grows to about 30" tall it is a popular ground cover in this area. The feature that separates it from other members of the genus is the formation of underground nodes for storing food and water. There are a number of named cultivars including 'Plumosa', 'Petticoat' and 'Duffii'. The highly popular 'Kimberly Queen' is often listed as being a cultivar of N. obliterata but it, in fact, belongs with the other cultivars of this species. [Tropical to temperate; Terrestrial, Epiphytic] 11B

Nephrolepis exaltata
Sword Fern, Boston Fern. Florida, Mexico, Brazil, West Indies. The principal feature of the species is its extreme variability and as result there are hundreds of varieties and cultivars. Many of them are named but there are so many that it is next to impossible to keep them defined and identified. Most of the fancy cultivars are sterile and must be propagated from the runners or stolons that cause the plants to spread rapidly, or by tissue culture. The first mutant to be noticed by the public was actually found in Philadelphia but had been shipped to Boston and became the famous 'Boston Fern'. Although these various forms are usually grown in pots or baskets because they tend to have a drooping habit the fern is really terrestrial. [Temperate to semi-tropical; Terrestrial] 11B

Nephrolepis falcata
Weeping Sword Fern. Thailand, Vietnam, Malaysia. This beautiful fern is much more climatically tolerant than its origins would indicate and grows happily here. Fronds may grow to eight feet and are best displayed by planting in a large basket. If kept damp it will grow in full sun. The most popular form is known as N. falcata 'Furcans'. It is commonly known as the 'Fishtail Fern' as each pinnule is regularly forked to look like a fish tail. Tropical to semi-tropical; Terrestrial, Epiphytic] 17B

Nephrolepis lauterbachii
(No common name) New Guinea. We don't know much about this little beauty except that comes from the highlands of New Guinea. It remains a delicate, graceful dwarf that probably grows on trees. It is marginal for outdoor growing here, particularly in areas which freeze. [Tropical to semi-tropical; Epiphytic] 3B

Niphidium crassifolium
(No common name) Mexico, Central and South America. This fern was known until recently as Polypodium crassifolium. It is a large epiphyte with fairly heavy erect simple fronds to a length of 60 in.

Osmunda japonica
(No common name). Japan, China, Philippines, North India. Very similar to O. regalis but is somewhat smaller and bushier. New growth is red. The plant is completely dimorphic with the fertile fronds smaller and completely curled. Grows very easily here in rich acid soil and is green for most of the year. [Temperate to semi-tropical; Terrestrial] 10C

Osmunda lancea
(No common name). Japan. This beautiful fern is smaller than O. regalis and its narrow pinnules give it a rather lacy appearance. It supposedly grows easily in rich, well drained acid soil but is seldom seen here. [Temperate to semi-tropical; Terrestrial] 10C

Osmunda regalis
Royal Fern. Europe, Asia, North & South America, Africa. This is a spectacular tall fern (to 10 feet) which lives in damp soil, usually near the edge of permanent water. The European form, O. rigidula v. rigidula, is slightly different from the American form, O. rigidula v. spectabilis, but the differences are hard to find. They are deciduous in winter in most climates, even here. There are several cultivars of v. regalis with varying degrees of crisping and splitting of the pinnules. They are generally smaller than the species. There is a third form of the species, O. regalis v. brasiliensis, which is the south American form of the fern. It seems to be somewhat smaller and less deciduous than the other species and grows more easily here. [Temperate to semi-tropical; Terrestrial] 15C

Phlebodium Genus
Rabbit's Foot Ferns. Florida, Mexico, Central and South America, West Indies. Three species of very similar plants once included with the Polypodiums. Both epiphytic and terrestrial they have large fuzzy rhizomes and long pinnatifid fronds, often of a bluish green color. They are distinguished primarily by the pattern of the sori on the back of the pinnules. P. pseudo-aureum (or P. areolatum) has a single row of sori, P. aureum has a double row and P. decumanum has several rows of scattered sori. It also has its fronds more separated on the rhizome giving it an open airy look. There are a number of named cultivars or hybrids such as 'Mandianum', 'Mexican Tasseled' or 'Cristatum' in which the pattern of sori is highly variable making assignment to a species very difficult. [Temperate to tropical; Terrestrial, Epiphytic] 13B

Phymatosorus diversifolius
Kangaroo Fern. Australia, New Zealand. Also known as Microsorum diversifolium. A striking dark green fern with fronds to 2 ft. In length. With a creeping green rhizome it is at home on tree branches, scrambling on rocks, in baskets or on slabs, or even on the ground.

Phymatosorus parksii
(No common name) Fiji, Samoa, Lord Howe Island. Also known as Microsorum parksii. A clumping fern with erect, pinnatifid, dark green fronds. It likes sandy soil and quite a bit of sun. Grows well in coastal regions and should do well here. Makes a good pot plant. [Tropical to Temperate; Terrestrial] 8B

Phymatosorus scolopendria
East Indian Polypody. Pantropical. Also called Microsorium scolopendrium by some botanists. This is a medium-sized fern that has a creeping, branching rhizome. It prefers high light and a drained garden soil or mix. It will tolerate some sunshine and is nearly hardy. It should do well here. [Tropical to semi-tropical; Epiphytic] 7B

Platycerium alcicorneSlide004
(no common name) Africa, Madagascar, Seychelles. There is some disagreement among botanists about this species. Often it is called P. vassei in the trade. The upper part of the base shields on plants from Madagascar are "crinkled" and ridged whereas those from Africa are smooth. These plants present no special growing requirements for the Southern California grower. These plants have off-shoots (pups) quite readily and are generally to the collector and are seldom grown from spore. [Tropical to semi-tropical; Epiphytic] 21C

Platycerium andinumSlide009
American Staghorn. South America. This is the only new world Platycerium. This is a very handsome plant that has a narrow base and tends to grow tall. The plant has many fine hairs and appears to be somewhat lighter green than most. These plants are rare and are given special care and treatment in greenhouses. They need bright light and modest watering. They are said to suffer during heat waves. This plant does pup and presents no special problems in growing from spore. [Tropical to semi-tropical; Epiphytic] 21C

Platycerium bifurcatum
Common Staghorn, Elkhorn. Australia. The species name comes from the word "bifurcate" which means to divide or fork. This describes the branching shape of the fertile fronds. Bifurcatum has generally narrow fertile fronds, upright with the ends drooping. New shields form in late summer and fall. Fertile fronds form most of the year. Many named cultivars are grown. Grows outside in Southern California. [Temperate to semi-tropical; Epiphytic] 19A

Platycerium coronariumSlide015
Disk Staghorn. Indonesia. The name means 'crown' which describes the shape of the mature shield fronds. Shield fronds are lobed along the top and are light green, waxy, and corky. In nature, P. coronarium is almost always ant inhabited. This staghorn is difficult to establish and takes special conditions to grow in Southern California. [Tropical; Epiphytic] 21C

Platycerium elephantotisSlide026
Lettuce Staghorn. Tropical Africa. This distinctive staghorn has a large massive basal shield. Its fertile frond is long and wide and does not divide. There is some disagreement about the name with some botanists still favoring P. angolense. This is not an easy plant to grow and is usually kept in hot houses. It likes very bright light and can withstand drought quite well. This species does produce off-shoots (pups) and is not generally grown from spore. [Tropical; Epiphytic] 21C

Platycerium ellisiiSlide029
(no common name) Madagascar. In this plant a yellow green color and waxy coating are normal. It grows round shield fronds in the spring and early summer and grows fertile fronds in late summer and fall. The fertile fronds are wide and divided into two points near the tips. Collected from mangrove groves at sea level. Requires special care because of its shallow roots and rhizome that grows quickly upward. The plant must be trimmed and remounted often. It needs greenhouse protection here. [Tropical; Epiphytic] 21C

Platycerium grandeSlide034
(no common name) This species grows natively in the Philippines. This is very large plant with a wide base frond often three to four feet in width. The top of the base is more upright than its counterpart, P. superbum and it has two large spore patches on each fertile frond. P. grande is rare in cultivation and tends to be overprotected. It is said to be less tolerant of the cold than P. superbum and requires less water than bifurcatum. This species does not produce pups and propagates only from spore. Grows outside in at least coastal Southern California. [Tropical to semi-tropical; Terrestrial] 21B

Platycerium hilliiSlide037
Green Staghorn. Australia and Papua New Guinea. P. hillii has wide, deep green fertile fronds. Growth requirements are similar to the Common Staghorn, P. bifurcatum, which makes it easy to grow here. The tops of the shield fronds tend to grow flat against the mounting surface, making it difficult to water. Pups easily with sufficient moisture and light. [Tropical to semi-tropical, Epiphytic] 20A

Platycerium holttumiiSlide045
(no common name) Thailand, Vietnam, Laos. This plant can have a very large basal shield and several fertile fronds. It resembles the P. grande, P. superbum and P. wandae and is very difficult to distinguish from the latter.. These plants require hot house conditions during California winters. They tend to rot if given too much water and enjoy having a lot of light. This plant is reproduced from spore. [Tropical; Epiphytic] 20B

Platycerium madagascarienseSlide050
(no common name) Madagascar. This small species has a unique basal shield that is heavily ridged and presents a most distinguished appearance. The fertile frond is split near the tip. The plant is rare and highly desirable. This plant requires a hothouse and prospers when provided with warm, humid conditions. The plant occasionally develops off-shoots (pups) and is also grown from spore. [Tropical; Epiphytic] 21D

Platycerium quadridichotomumSlide052
(no common name) Madagascar. This plant is small by comparison to many other platyceriums. It is a species rarely seen and seldom owned. It has a large upright base shield and longer fertile fronds, appearing like a miniature superbum. Little is known about their growing requirements but here they must be grown in protected greenhouses. They are grown with less water than most staghorns and are said to withstand drought. This species can be grown from pups and is not too difficult to grow from spore. [Tropical; Epiphytic] 21D

Platycerium ridleyiSlide057
(No common name) Malaysian Peninsula). This fern is named after the botanist, J. Ridley. The fronds bear a wonderful resemblance to deer antlers, truly earning the name "Staghorn." This is the smallest Platycerium that reproduces only by spore. It is often found on tree branches more than 80 feet above the ground. It needs air movement and bright light and is extremely difficult to grow. [Tropical; Epiphytic] 21D

Platycerium stemariaSlide061
Triangle Staghorn. Tropical Africa. This staghorn has a unique deep green fertile frond that is often very wide. The basal frond is narrow and the shield remains erect. The fern requires temperatures in excess of 55 degrees. It prospers when kept wet. This plant grows off-shoots (pups) easily and is generally not grown from spore. [Tropical; Epiphytic] 21C

Platycerium superbumSlide066
Giant Staghorn. The mature P. superbum makes a most striking exhibit in a collection. Its base shield is about four feet in width and the fertile frond descends about four feet. Its growing requirements include indirect light in a sheltered location that will protect it from sun and wind. The grower should avoid excessive watering as the mature plant stores a considerable amount of moisture. This species does not produce pups (off-shoots) and is reproduced only by spore. Grows easily outdoors in Southern California. [Tropical to semi-tropical; Epiphytic] 21A

Platycerium veitchiiSlide072
Silver Elkhorn. Australia. P. veitchii is closely related to P. bifurcatum, but is covered with a great amount of white hair. The tops of the shield fronds grow into thin fingers. It has very upright fertile fronds. High light with some sunshine and limited moisture provides the most distinctive specimens. Easy to over water. Grows outside in Southern California. [Tropical to semi-tropical, Epiphytic] 19B

Platycerium wallichiiSlide075
Indian Staghorn. Thailand, Malaysia. This is a very rare and unusual Platycerium. It has an upright base shield and large, lobed fronds. It is a very attractive plant but is difficult to grow and is said to rot quite easily. Those who have owned this species have no general agreement as to its growing requirements. The plants seem to require alternate wet and dry periods and are not hardy. In Southern California they must be given hot house protection. These plants are propagated from spore that, unlike any other Platyceriums, is green. [Tropical, Epiphytic] 21C

Platycerium wandaeSlide080
Queen Staghorn. New Guinea. When fully grown, this is a very spectacular staghorn and under favorable conditions will grow even larger than P. superbum. Its basal shield grows upright and is very large. Its fertile fronds are short. These plants are generally grown out of doors and should be sheltered during cold weather. They are easily grown, but not cultivated in great abundance. This plant does not produce off-shoots (pups) and is reproduced only from spore. [Tropical to semi-tropical; Epiphytic]

Platycerium. willinkiiSlide083
Java Staghorn. Australia, Indonesia, New Guinea. This easy-to-grow staghorn is closely related to P. bifurcatum and is often called a sub-species of it. The shields are different by being taller and more deeply lobed. The tops of the shield fronds often lose all their tissue except the veins. The long fertile fronds hang down. P. willinkii does well in medium light and moist moss. Needs slightly higher temperatures than P. bifurcatum, but it easy to grow in Southern California. [Tropical to semi-tropical, Epiphytic] 19B

Pleopeltis polypodioides

When dry it closes into a ball only to open again in the presence of moisture. [Tropical to semi-tropical; Epiphytic] 1B

Polypodium formosanum
Green Caterpillar Fern. Japan, Taiwan, South China. A long creeping fern with once pinnate light green fronds and lime green rhizomes that give its common name. It grows well here in a basket, particularly one made of tree fern fiber, which the fern will engulf. It goes dormant during the summer months and grows strongly during the winter. The is one rather strange variant which is known as a 'crested' form because of the spreading nature of the ends of the rhizome. [Tropical to semi-tropical, Epiphytic] 8B

Polypodium guttatum
(No common name) Central Mexico. Fronds look a bit like a small Phlebodium aureum with scattered scales on the underside. It grows on rocks or in soil in oak and oak-pine forests at altitudes up to 8000 feet. Like other Mexican Polypodiums it should grow well here in a basket or in the ground. [Semi-temperate to semi-tropical; Epipetric] 2B

Polypodium meniscilfolium
(no common name) Mexico, Central and South America. This fern has also been called P. fraxinifolium. This is medium-sized fern with a creeping, branching rhizome and long arching dark green fronds. It makes a good pot or basket plant. [Tropical to semi-tropical; Epiphytic] 7B

Polypodium pyrrholepis
(No common name) Mexico. Epiphytic in the wet montane forests. Fronds are spaced out on a small reddish rhizome. Pinnules grow along a frond up to 20" long.
