Identification

B. tokioi has creeping rhizomes (0.5 mm diam.), lacking pseudobulbs. Its fleshy, sessile, glabrous leaves are minute (5–6 mm long by 3-4.5 mm wide), elliptic or elliptic-orbicular, acute or obtuse, some having tiny, membranaceous sheaths at base. It has axillary scapes (1–3 cm long) that are slender and erect, with a few sheaths close by its base. Bracts are elliptic and acute.

B. tokioi has two palely yellowed flowers, sometimes having red spots or striations. Its three-nerved, dorsal sepals are membranaceous and hairless. One of these (2.5-3.8 mm long by 1–2 mm wide) is oblong, while other lateral ones (2.6–4 mm long by 1.5–2 mm wide) are obliquely triangular and elliptic. Its single-nerved petals (1.3-2.4 mm long by 0.6–1 mm wide) are oblong. Its lip is attached to the apex of its thin, un-hornlike column foot (2-2.4 mm long by 1 mm wide) is ovate-triangular and purple-tinged, with a rounded to obtuse apex, and a base decurrent into a long, entire, glabrous, membranaceous, three-nerved claw. The column (0.8–1 mm long), has stubby stylids at its apex, and its foot is 2 mm long. Its triangularly conic anther is white with an area of red, and its two pollinia are ovoid to ellipsoid.
