Lecanopteris

 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. Rhizome scales small, dark, somewhat round and with a strongly dentate margin 

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" sturdy fronds rise from growing tips.

 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 three to four centimetres in diameter, forming clusters of 50 centimetres. The leaves up to 25 centimetres long.

The genera name after some Lecan, but I fail to figure which one, or perhaps Greek lekane; 'bowl', and Latin pteris; 'fern'.

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 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.
