Common Name The Varicose Veined Bulbophyllum [refers to the thickened veins on the adaxial surface of the lip]

Flower Size .44" [1.1 cm]

Found in western New Guinea in dense primary ridge-top forests at elevations around 600 meters as a creeping medium sized, hot to warm growing epiphyte with close set, obliquely erect, ovoid pseudobulbs carrying a single,, apical, erect, obovate, acuminate, gradually narrowing below into the .8 to 1" [2 to 2.5 cm] long, petiolate base leaf that blooms in the later spring on a basal, erect to patent, to 1.6" [4 cm] long, single flowered inflorescence with a tubular, apiculate floral bract.

J J Vermeullen states that "Bulbophyllum variculosum shares an ovate lip with protruding nerves and two ridges converging over the adaxial surface with B. samoanum Schltr. (Wickison 139, K, seen from the Solomon Islands), but it differs in having triangular stelidia with a distinct wing along the lower margin. Bulbophyllum cerinum Schltr. has a similar lip, but without thickened nerves. It also lacks the wings along the lower margins of the stelidia."

B brachygnomon differs in the deltoid stellida of the column with a rounded to minutely acuminate apex.
