`SECTION Pseudopelma J J Verm & Peter O'Byrne 2003

TYPE species = Bulbophyllum longissimum (Ridl.) J.J. Sm. 1912

Epiphytes formerly within Desmosanthes with creeping or straggling rhizomes giving rise to coarsly papillose roots and finely and densely papillose rhizome bracts from which arise single leafed pseudobulbs that have new growths arise from nodes below the pseudobulbs but not fused to them. The persistent leaves have thin inconspicuous veins. The inflorescence arises from nodes beneath the pseudobulb or from nodes scattered along the rhizome as solitary or few fasiculate, 1 to 5 flowered, elongate racemes, peduncle with 2 to 3 bracts, rachis not thickened, carrying resupinate, simultaneously opening if racemose flowers with the basal node of the pedicel below the attachment of the floral bract. The sepals are free, almost equal, elliptic to triangular, acute to acuminate and have entire margins. The petals are 3 veined with entire, glabrous margins. The proximal edge of the stigma is truncated by a transverse ridge or a triangular tooth. The anterior surface of the anther is not concave nor is it drawn out. There are 4 pollina with the inner ones half the size of the outer ones.

These 2 species were within Desmosanthes but were removed as they differ in the coarsly papillose roots and finely and densely papillose rhizome bracts and the proximal edge of the stigma is truncated by a transverse ridge or a triangular tooth

There are 2 species in this section from the lowlands of Sulawesi.

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.
