Common Name The Stake Shaped Pseudobulb Bulbophyllum
Flower Size .16” [4 mm]
Found in Borneo in tall mossy forests, ridge top forests on tree trunks in shade at elevations of 1500 to 2100 meters as a small sized, cool to cold growing epiphyte with an erect to patent [creeping in juvenile plants] rhizome with [.4 to 3.3 cm] between each minute, discoid, not laterally flattened pseudobulb carrying a single, apical, elliptic to ovate lamina becoming conduplicate below or terete, obtuse to acute, narrowing below into the petiolate base leaf that blooms in the fall on a suberect to erect, peduncle 1.4 to 4.4” [3.5 to 11 cm] long, rachis porrect to arching, 1.6 to 6.2” [4 to 5,5 cm] long, 3.2 to 10.8” [8 to 27 cm] long overall, dense, 13 to 40 flowered inflorescence carrying mostly simultaneously opening flowers.
Vermuellen states that the only specimen that he has seen with caudate sepals is the type which is the drawing provided so most plants have much shorter sepals and that both the terete leaved form and the elliptic to ovate form are fairly common. Peter O’Byrne [Pers Comm] states that the only part of the drawing above that is helpful for identification is “F” the side view of the column and lip.
