Found in Irian Jaya New Guinea in montane riverine forest at elevations of 1900 to 2100 meters as a small sized, cool growing epiphyte with a creeping, pendulous rhizome giving rise to porrect, distant, cylindrical or slightly obovoid, the new shoot arising from the top of the pseudobulb carrying a single, apical, erect, ovate, acute-acuminate, sessile leaf that blooms in the late spring on a .28" [.7 cm] long overall, peduncle 0.3 cm long, provided with 2 porrect, non-floriferous bracts, the longest ca .14" [3.5 mm] long, single flowered inflorescence and a tubular, acute, longer than the ovary floral bract

According to Vermuellen "Bulbophyllum stemonochilum is most similar to B. bisepalum Schltr. and B. stenochilum Schltr. in having a narrow, linear lip. It differs, however, in having ciliolate (not glabrous) sepals, truncate to emarginate, apiculate (not acuminate) petals, and a lip with ciliate margins only in the middle third."
