*`SECTION Hymenobractea Schlechter 1913

TYPE species = Bulbophyllum infundibuliforme J.J. Sm. 1830-4

This section is made up of epiphytes with a creeping rhizome giving rise to a minute pseudobulb carrying a single persistent leaf that blooms on a patent to erect, 1 to 10 flowered inflorescence carrying non-resupinate, distichous flowers with the pedicel basal node above the attachment of the amplexicaul, often proximally tubular floral bract. The sepals are 5 to 9 veined with a broadly attached base, the laterals are 1 to 1.4 times as long as the dorsal, and the laterals are united at the base to the column foot forming a mentum. The petals are 3 to 5 veined with a broadly attached base and have entire margins. The distinctly recurved at 1/3 to 1/2 of its length, mobile lip has a thin ligament and is entire. The column is often proximally protruding or has 2 protruding teeth and a column foot. The stelida are 1/2 the length of the column or shorter with or without a tooth along the upper and lower margins. The anterior surface of the anther is not concave and the anterior margin is not to slightly drawn out. There are 4 pollina.

There are 2 species in montane forests at elevations up to 1500 meters in Papua New Guinea

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. If a sectional name has a "`" in front then it is a complete section with all the known species represented.
