Bulbophyllum hirsutiusculum

A small epiphytic Bulbophyllum endemic to the humid evergreen forests of eastern Madagascar, known from a handful of sites between about 600 and 1500 m. It is listed as Endangered and is threatened by collecting and wood-cutting. Very little is published about it, so grow it like other mid-elevation Malagasy Bulbophyllum: shaded, intermediate, humid and never dry.

Collections come from about 600–1500 m; most recent ones are near 1000 m, and the type locality on Mont Papanga is at 1500 m.
