Common Name The Thick Leaved Bulbophyllum

Flower Size 1" [2.5 cm]

Found in Ppaua New Guinea in shrubs at elevations of 2500 to 4000 meters as a miniature sized, cold growing epiphyte with a creeping rhizome giving rise to distinct, ovoid-cylindrical, hardly angular pseudobulbs carrying a single, apical, erect, thick, obovate-oblong, c. 6.4 by 0.7 cm, index 9.19.2; apex subacute, petiolate base leaf that blooms in the winter on a single or few together, c. 9.6" [24 cm] long, 1-flowered; peduncle c. 6.8" [17 cm] long, single flowered inflorescence with much shorter than the ovary floral bracts and 'pale' colored flowers.

"Most similar to Bulbophyllum dologlossum, differs by the acute sepals, the 4-veined (versus 1-veined) petals, the ovate-oblong lip, gradually tapering without narrowed parts towards the apex, with only 2 (versus 4) ridges on the adaxial side, and the straight stelidia."
