Bryobium

Orchids in the genus are epiphytic or lithophytic herbs with thread-like roots and relatively large, fleshy pseudobulbs that are usually covered by papery bracts when young. Each pseudobulb has up to three flat, usually leathery leaves. The flowers are usually white, cream-coloured or pinkish, do not open widely and last for up to a few days. The dorsal sepal is free but the lateral sepals are fused to the base of the column. The petals are free from each other and usually smaller than the sepals. The labellum often has three lobes, in which case the side lobes are erect.[3][4][5]

The genus Bryobium was first formally described in 1836 by John Lindley who published the description in A natural system of botany, or, A systematic view of the organization, natural affinities, and geographical distribution, of the whole vegetable kingdom.[2][6] The name Bryobium is derived from the Ancient Greek words bryon meaning "moss"[7]^:535 and bios meaning "life",[7]^:478 an apparent reference to the habit of plants in this genus.[5]

Orchids in the genus Bryobium grow on the upper parts of rainforest trees or on rocks and boulders. They occur in China, the Indian subcontinent, Cambodia, Laos, Vietnam, Borneo, Java, the Lesser Sunda Islands, Peninsula Malaysia, Sulawesi, Sumatra, Christmas island, New Guinea, the Solomon Islands, Queensland, Australia and New Caledonia.[2]
