Common Name The Folded Stigma Bulbophyllum

Flower Size .16" [4 mm]

Found in Papua New Guinea in high primary forests at elevations around 450 meters as a miniature sized, hot growing epiphyte with a short creeping rhizome giving rise to close set, obliquely erect, ovoid pseudobulbs carrying a single, apical, elliptic to obovate, acute, petiolate base leaf that blooms on an erect, 2 bracted, 1.2" [3 cm] long, single flowered inflorescence with an tubular, acuminate floral bract.

According to J J Vermuellen - "Bulbophyllum ptychostigma is most similar to B. dichilus Schltr. and B. eciliatum Schltr. B. ptychostigma differs in having a floral bract much longer than the pedicel-withovary together. It also differs from B. dichilus in not having a distinct callus at the base of the lip, and from B. eciliatum in having a lip which is not constricted in the distal half."
