LATER 
Common Name The Comb-Like Bulbophyllum [Refers to the Comb-Like Rim Of the Lip] - In China Chang Zu Shi Dou Lan
Flower Size 2" [5 cm]
Found in southern China, Myanmar, Thailand, Vietnam, Cambodia, Laos, India and Taiwan on wooded slopes at elevations of 1000 to 2500 meters as a mini-miniature sized, hot to cool growing, unifoliate epiphyte with ovoid pseudobulbs carrying a single, apical, elliptic, petiolate below leaf that blooms in the later spring and summer on a stout, 2 3/8" [6 cm] long, single flowered inflorescence that arises at the base of a newly developed pseudobulb and holds the flower at leaf height.
This species grows in hot to cool temperatures, partial shade and ample moisture and can be in a pot, basket or mounted on a slab of tree fern.
Very similar to B transarisanensis and may be conspecific with, but I have left them separate. There are differences in the angle of the lateral lobes of the comb-like lip and in the amount and length of the hairs.
