Plant small, when growing in shade reaching a height of c. 25 cm, generally much less. Tubers on long axes, to 8 cm from parent plant. Inflorescence for the most part less than 3 cm long, flowers few, usually 2—10, often widely spaced. Dorsal sepal c. 2.5 mm long, its margin evenly rounded and lacking recurved tip; laterals deflexed, usually lying parallel to ovary. Labellum also sharply deflexed; tip squarely truncate to slightly emarginate, not apiculate; margins shallowly crenate, sometimes thickened but rarely undulate; anterior callus wartlike, variously developed, often low and broad; two basal calli smoother, squarish, flat rather than convex, together occupying most of the width of the labellum.

Planta parva, 3-15 cm alta, rarissime altitudinem 25 cm attingens. Inflorescentia c. 2-10-flora, plerumque <3 cm longa. Sepalum dorsale subacutum vel obtusum, haud recurvatum; sepala lateralia dependentia, raro circinata. Labellum abrupte deflexum, apice truncatum sine apiculo, marginibus leviter crenatis; callus anterior verrucosus, magnitudine variabilis; calli basales quadrati, complanati, labelli totam latitudinem fere occupantes.

Plant at fl. mostly c. 3–15 cm. tall, occ. to 25 cm or more. Stem erect, fleshy. Lf overtopping raceme if undamaged but very commonly cropped short. Raceme rarely > 3 cm. long; fls 1–10, often widely spaced, especially on taller plants. Per. green. Dorsal sepal c. 2.5 mm. long, its margin evenly rounded and lacking recurved tip; lateral shorter, ± acute, deflexed, us. straight. Petals ± under dorsal sepal. Labellum oblong, only rarely narrowed at mid-length; tip us. squarely truncate, sts slightly emarginate, not apiculate; margin papillose, shallowly crenate, sts thickened but rarely undulate; anterior callus variously developed, verrucose; large basal calli squarish, flat rather than convex, us. continuous at the sides with narrow band of callus behind slit-like transverse furrow; labellum rather sharply deflexed to hang ± parallel to ovary. Base of column often broader than stigma.
