Common Name The Ribbed Bulbophyllum [referes to the ridges on the sepals]
Flower Size 2.56" [6.4 mm]
Found in the Philippines at elevations around 600 meters as a small sized, warm growing epiphyte with to 2.4" [to 6 cm] between each tapered, ascending, sometimes slightly curved, wrinkled, cylindrical, sometimes with a blunt angled pseudobulb carrying a single, apical, erect, thin, almost papery in texture, oblong to elliptic leaf that blooms on a basal, horizontal, 3.2" [8 cm] long, single flowered inflorescence.
CAUTION! Many references including Kew put this species as a synonym of B membranifolium but it is obviously diffferent in many respects.
