TYPE species: Bulbophyllum kingii Hook.f. 1890

Epiphyte with a creeping rhizome giving rise to longitudinally wrinkling with age pseudobulbs carrying a single, persistent leaf that blooms on a subumbellate to an elongate racemose inflorescence carrying spirally arranged, resupinate flowers that have the basal node of the pedicel above the attachment of the floral bract. The sepals are free, more or less equal and have glabrous to ciliate to fimbriate margins and are 7 veined. The 3 veined petals are ciliate to fimbriate and the surface is glabrous. The lip is mobile on a thin ligament and is auriculate. The stigma is not proximally protruding on the column and the stelida are shorter than 1/2 the length of the column. The anterior surface of the anther is not concave and the anterior margin is somewhat drawn out or not. There are 4 pollina with bifid stipes.

There are 3 species in this section occuring in semideciduous forests at elevations up to 1300 meters from India to Vietnam and South to Thailand.

Entries below with an asterix are listed in publications by J J Vermeullen etal.[2014/15] and so are more likely correct than ones without. Species with a question mark in front, seem to me to not conform and so please use with caution. If a sectional name has a "`" in front then it is a complete section with all the known species represented.
