Bryobium eriaeoides
Bryobium eriaeoides, commonly known as the brittle urchin orchid, is an epiphytic or lithophytic clump-forming orchid that has fleshy, green pseudobulbs, each with two leaves and between three and twelve cup-shaped white to purplish flowers but that sometimes remain closed. This orchid occurs in New Guinea and Queensland. Description. "Bryobium eriaeoides" is an epiphytic or lithophytic herb that forms large clumps with cylindrical pseudobulbs long and wide covered with papery white bracts when young. Each pseudobulb has a thin elliptic to lance-shaped leaf long and wide. Between three and twelve cup-shaped, resupinate white to  purplish flowers long and wide are arranged on a flowering stem long. The flowers are self-pollinating and open only slowly or not at all. The sepal and petals are about long and wide. The labellum is about long and wide with three lobes. The side lobes are erect and the middle lobe triangular with three ridges. Flowering occurs from August to October. Taxonomy and naming. The brittle urchin orchid was first formally described in 1888 by Frederick Manson Bailey who gave it the name "Dendrobium eriaeoides" and published the description in "A Synopsis of the Queensland Flora". In 2002  Mark Clements and David Jones changed the name to "Bryobium eriaeoides". The specific epithet ("eriaeoides") refers to the similarity of this species to those in the genus "Eria". The ending "-oides" is a Latin suffix meaning "like", "resembling" or "having the form of". Distribution and habitat. "Bryobium eriaeoides" grows on trees and rocks in humid situations. It is found in New Guinea and Queensland from the Iron Range to near Townsville.
