Bulbophyllum obyrnei

A tiny single-leaved Bulbophyllum from New Guinea, named in 1995 for the orchid botanist Peter O'Byrne. It is based on the older name Osyricera ovata, collected at Ambasi in Papua New Guinea's Northern Province in 1907. Nearly sessile, leathery, ovate leaves sit on a nodular creeping rhizome and bear single flowers about 6 mm across. It is best treated as a warm-growing miniature for a humid terrarium or mount.

Where it grows wild

It is an epiphyte. IOSPE places it in lower montane forest in western New Guinea but calls it hot-growing, and it appears in O'Byrne's Lowland Orchids of Papua New Guinea. The only georeferenced record, from Ambasi, is near the coast. Details of host trees and microhabitat are not recorded.

Not recorded. The evidence points to lowland to lower montane forest, perhaps from near sea level to about 1,000 m.
