Type = Bulbophyllum hemisterranthum J.J.Verm. & P.O'Byrne 2008

Epiphytes with creeping rhizomes giving rise to a single, persistent leaf that blooms on a single flowered inflorescence carrying resupinate flowers with the basal node of the pedicel above the attachment of the floral bract. The usually free sepals are more or less equal and are usually 3 veined. The petals are single veined and have entire to erose, glabrous to papillose margins. The mobile, undivided, fleshy lip is on a thin ligament, the column stigma is often proximally protruding and the column foot is with or without an apical dorsal tooth. The stelida are often with a dorsal tooth along the upper or lower margin. The anterior suface of the anther is concave or not and the anterior margin can be drawn out into a beak or not and there are 2 or 4 pollina.

There are only 2 species in this section confined to Sulawesi at elevations up to 1200 meters within montane forests.

Entries below with an asterix are listed in publications by J J Vermeullen 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.
