Drawing by J J Vermeulen

Part shade Cool Spring

Common Name The Horned Bulbophyllum [refers to the horns on the lateral sides of the lip]

Flower Size .2" [5 mm]

Found in Papua New Guinea in montane forests at elevations around 1100 meters as a small sized, cool growing epiphyte with a creeping rhizome giving rise to distinct, .2 to .4" [.5 to 1 cm] between each, ovoid, hardly angular pseudobulbs carrying a single, apical, elliptic to obovate, with acuminate apex, petiolate base leaf that blooms in the spring on few to many together, peduncle .032 to .076" [.08 to .19 cm] long, provided with c. 3 sheaths, 1.4 to 1.8" [3.5 to 4.5 cm] long overall, single flowered inflorescence with a much shorter than the ovary floral bract.

Bulbophyllum cerastes J.J.Verm., Schuit. & de Vogel is unique in SECTION Polymeres Verm & O'Byrne 2008 by the retrorse horns formed by the lateral lobes of the lip.

"Bulbophyllum cerastes is similar in this character to Bulbophyllum trutiniferum J.J.Verm., Schuit. & de Vogel, a species intermediate between and SECTION Polymeres Verm & O'Byrne 2008 , but it differs in the free sepals (versus sepals connate at the base), the wide, obovate petals with index c..6" (versus petals narrowly ligulate with index 4 to 5) papillose at the apex (versus apex glabrous), and the straight stelidia (versus stelidia curved downwards)."
