Found in the Philippines on Mindanao Island on mossy branches at elevations around 1200 meters as a mini-miniature sized, cool growing epiphyte with erect, clustered, globose pseudobulbs carrying a single, lanceolate, flattened, apex emarginate, adaxially and abaxially glabrous, margins entire, cuneate below into the glabrous, grooved, petiolate base leaf that blooms in the late winter and early spring on an axillary, erect, peduncle acicular, .76" [1.9 cm] long, racemose, up to 1" [2.5] long, rachis erect, to 6 flowered inflorescence with triangular, persistent, glabrous, green, shorter than the ovary floral bracts and carrying resupinate, non fragrant flowers.

"Bulbophyllum puberulosum is most similar to Bulb. crassiusculum Cabactulan, Cootes, M.D. De Leon and Pimentel, but differs in the size of the flowers, .24" [6 mm] across the lateral sepals in Bulb. crassiusculum versus .172" [4.3 mm] across the lateral sepals in Bulb. puberulosum; the shape of the leaves in Bulb. crassiusculum are semi-terete, whereas the leaves of Bulb. puberulosum are flat."
