Common Name The Downward Pushed Bulbophyllum [refers to the prostrate pseudobulbs and leaf]- In China Ji Chun Shi Dou Lan

Flower Size 1/8" [3 mm]

Found in India, China, Thailand, Malaysia, Borneo, Sumatra and Java at elevations of 600 to 2000 meters in hill and lower montane forests usually on trunks and large branches without moss as a miniature sized, warm to cool growing epiphyte with close set [not always], ovoid to ellipsoid, slightly flattened and canted to the side pseudobulbs carrying a single, apical, rather thick, ovate, medium to dark green, shortly petiolate leaf that blooms in the summer and fall on a basal, lateral to arching, 3/4" [1.2 cm] long, single flowered inflorescence arising from the rhizome and carrying tubular floral bracts and a flower that does not open well. I am going with Kew here although I have not seen King & Pantlings drawings to see if it is so but all other references give the name B acutum..

Very similar to B acutilobum but B depressum differs in having acute to acuminate petals and the rounded lateral lobes of the lip.

Synonyms Bulbophyllum acutum J.J.Sm. 1905; Bulbophyllum hastatum Tang & F.T.Wang 1974
