TYPE: = Bulbophyllum lepanthiflorum Schltr. 1913
Synonyms SECTION Trachyrachis Schlechter 1913
This section has creeping rhizomes giving rise to shoots proximally fused to the minute pseudobulb carrying a single apical, persistent leaf that blooms on a racemose, many flowered inflorescence with spirally arranged, resupinate flowers that has the pedicel basal node above the attachment of the floral bracts. The free equal sepals have an apical, fleshy subulate projection and the margins are glabrous, to papillose to ciliate, usually 3 veined, abaxially keeled or not. Dorsal sepal free, laterals sometimes connate along their lower margins. The petals have a single vein and their margins are erose, entire, glabrous to ciliate. The undivided or trilobed, mobile lip is on a thin ligament. The rostellum of the column has an anterior surface that is even with the stelida apices, or receding in between these, the stigm is proximally usually protruding. The stelida are 1/2 or shorter than the length of the column and often have a tooth along the lower margin. The anterior suface of the anther is not concave, the anterior margin is drawn out to a beak or not and there are 2 pollina.
There are 17 species in this section from forests up to 3300 meters in New Guinea and the western Pacific Islands.
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.
