This miniature sized, hot to warm growing sometimes epiphytic and mostly lithophytic species is found in central Oaxaca state of Mexico in the transition zone between tropical deciduous forests and dry oak forests on limestone boulders or the trees above at elevations of 1600 to 1700 meters and has thickened, compressed, 3 to 8 noded stems enveloped completely by scarious, tubular leafless to leaf-bearing sheaths carrying 3 to 6, articulate to the leaf sheath, elliptic to narrowly ovate, acute, coriaceous to sub-fleshy leaves that blooms in the summer on a medium length to 15" [17.5 cm] long, laxly few to many flowered, racemose inflorescence arising from a newly developing stem carrying nonfragrant flowers.

This species and the similar B whartoniana differ mainly in the fact that this species has the column adpressed to the lip surface.
