Lecanopteris

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.

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.

 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.
