Part shade Hot

Common Name The Subbullate Bulbophyllum [refers to the somewhat bullate abaxial surface of the sepals]

Flower Size .12" [3 mm]

Found in Sarawak Borneo in primary forests at elevations around 50 meters as a mini-miniature sized, hot growing epiphyte with a creeping rhizome giving rise to distinct, .16 to .8" [.4 to 2 cm] between each, ovoid, not flattened pseudobulb carrying a single, apical, ovate, obtuse, petiolate base leaf that blooms on an erect to patent, peduncle to .28 to .36" [.7 to .9 cm] long, provided with 4 obtuse bracts, rachis .24" [.6 cm] long, single flowered inflorescence with tubular, acute, shorter than the ovary floral bracts and carrying dark purplish red flowers.

"Vegetatively, this species is difficult to distinguish from B. acuminatum Ridl. . The flowers are similar to those of B. auratum (Lindl.) Rchb. f. in most details, but the lateral sepals differ from any other species of *SECTION Ephippium Schlechter 1913 in being only slightly longer than the median sepal, and in having erose margins. Besides, the lateral sepals lack the twisting in the basal part, which brings their upper margins together; this character occurs in most species of the section." J J Vermeulen 1996
