Found on the Indonesian island of Sulawesi, growing as an epiphyte with lots of water and some sun. The caudex can grow to 6 inches in diameter, the entire plant from 10 to 18 inches in height. The spores are brown.  The species name in honor of the Indonesian botanist; Max Michael Josephus van Balgooy, 1932-2021. 

Found in Indonesia, Malaysia and the Philippines, growing on the branches of trees with some to lots of water and little to some sun. The rhizomes can grow from 1 to 2 inches in diameter, forming clusters of 20 inches. The leaves up to 10 inches long.

Found on the Indonesian island Sulawesi, growing on the branches of trees with lots of water and little to some sun. The rhizomes can grow to 3 inches in diameter, and form huge clusters. The leaves up to 12 inches long. The species name as it originates from  Celebes (now Sulawesi), an Indonesian island.

A lowland species native to the Malaysian Peninsular always found growing associated within mass roots of Platycerium ferns. It is only one of a few species that has flattened rhizome with red-brown dots scattered on. Its 4-5 inch sturdy fronds rise from growing tips.

 Found on the Indonesian island of Sulawesi, growing as an epiphyte with lots of water and some sun. The caudex can grow to a cluster of 8 inches in diameter, the entire plant from 8 to 24 inches in height. The spores are yellow.  The species is named after the Indonesian Taxonomist Dedy Darnaedi. 

Native to Malaysia and New Guinea.

The rhizomes are covered by a wax skin,

Very interesting and rare in collections. They form hollow rhizomes with glands emitting sugars thus working symbiotically with the ants whose waste provides nutrition to the fern.

Found on the Indonesian island of Sulawesi, growing as an epiphyte with lots of water and some sun. The caudex can grow to a cluster of 8 inches in diameter with the entire plant to being 32 inches in height. The spores are yellow.  The species is named after Richard Eric Holttum,1895–1990, a British botanist who worked in Singapore Botanical Garden 

 Found in the lowlands of northern Sulawesi; Indonesia and on the Philippines, growing on the stems of old trees, but grows fine in a well drained pot  with plenty of water and 50%  full sun. The rhizomes will grow 2 inches, forming clusters reaching 12 inches or more. The leaves reach about 12 inches in height. 

 Found on the Philippine island: Luzon, growing as an epiphyte with quite some water and sun. The caudex (-complex) can grow to 12 inches in diameter, the entire plant from 4 to 15 inches in height. The spores are yellow-brownish. 

 It is found in Papua New Guinea and the Indonesian island of Sulawesi. It grows in the trees with some water and some sun. The massive rhizomes will grow up to 12 inches in diameter, and the leaves will grow up to 24 inches. 

 Rhizome creeping and much branched, 0,5 to 1.0 in thick, fleshy, hollow and ant inhabited; bright pale green when young, blackening with age, glabrous except for a few scattered scales and hairs at apices and occasionally persistent in protected grooves of older parts.

Likely a cultivar  crustacea x mirabilis created by Charles Alford in Florida. The form stays closer to the mirabilis.

Likely a cultivar  crustacea x mirabilis created by Charles Alford but later developed by Carlos Tatsuta - a commercial fern grower  in Brazil. The form stays closer to the crustacea.
