Rhizome creeping or straggling; roots sprouting mainly below pseudobulbs, spreading; new shoots arising from basal node of pseudobulb. Pseudobulbs distinct, apex with 1 leaf. Leaves persistent, thick. Inflorescences solitary, arising near pseudobulbs, 1-flowered or 2-4-flowered in an elongate or contracted raceme. Pedicel with basal node coinciding with attachment of subtending bract, or no more than 1 × diam. of pedicel above it. Sepals free, ± equal in length or lateral sepals somewhat longer, margins glabrous, 5- or more veined. Petals: margins glabrous to erose, 5- or more veined (3-veined in Bulbophyllum ambrosia); lip with or without antrorse auricles along margins well above its base, margins otherwise glabrous to partly or entirely erose or denticulate, adaxially glabrous to variously verrucose or papillose. Column: stigma not protruding at its base, foot distinct; anther: front margin not or slightly projecting, abaxially with a high, conic crest (a small crest in B. ambrosia); pollinia 4, with or without stipe, inner more than 1/2 as long as outer.
Seventy-two provisionally accepted species: Himalayas to W Pacific; seven species in China.
