Found in Penninsular Malaysia in lower montane forests on tree trunks and branches at elevations of 1500 to 1800 meters as a small sized, cool growing epiphyte with close to distant, depressed conical pseudobulb carrying a single, apical, elliptic to ovate to obovate, acute to slightly acuminate, petiolate base leaf that blooms in the winter and spring on a basal, peduncle patent, 8.8 to 15.6" [22 to 39 cm] long, provided with 5 to 6 bracts, rachis slightly to nodding, spindle-shaped, flattened or not, [11 to 41 cm] long, glabrous, without blackish dots, elongated, lax, simutaneously single to few, 22 to 68 flowered inflorescence with triangular, acute longer than the ovary floral bracts and carrying flowers that do not open well.
B aithorhachis is the most similar species but it differs in having a much more slender rachis, narrower sepals, and in the distribution of the hairs on the margins of the lip. In B aithorhachis the adaxial side is distincly hirsute towards the apex while B setuliferum is glaborus except for a finely hisute patch near the base, also the hairs along the lip margin are somewhat club shaped but in B aithorhachis they are not.
