Found in Sulawesi in montane forest at elevations of 1200 to 1500 meters as a mini-miniature sized, cool growing epiphyte with a down hanging rhizome with non-persistent bracts giving rise to ovoid-cylindrical, prostrate on and fused to the rhizome, so that the new pseudobulbs arise from half-way the length of the old pseudobulb carrying a single, apical, erect, ovate, acute, narrowing below into the petiolate base leaf that blooms in the spring and summer on a porrect, peduncle ca .06 to .08" a [.15 to .2 cm], provided with bracts, raceme .32" [.8 cm] long overall, single flowered inflorescence with a tubular, acute, shorter than the ovary floral bract and carrying flowers do not fully open with the median sepal pinkish purple, whitish towards the base, with slighty darker veins, the lateral sepals pinkish purple, with a white patch near the base, petals translucent white. Lip pinkish purple, but white along the midvein and a white column.

"B. oncopus shares the general shape of the lip, with recurved margins in the top half, with B. oligochaete Schltr., from New Guinea. It differs in having ciliate sepals, the lateral sepals obtuse rather than broadly round, triangular, obtuse petals and stelidia without a tooth along the lower margin. B. loxophyllum Schltr., also from New Guinea is even more similar in the shape of the flower parts, but has eciliate lateral sepals and the margins of the lip not recurved."
