Plant c. 10–25 cm. tall at fl. Stem us. erect, smooth, internodes < lvs. Lvs mostly 4–5, the shape changing from below upwards; lamina c. 4–15 × 1–1.6 cm., the lowest, and those on non-flowering plants, elliptic, occ. broadly, subacute, subsessile or with winged petiole; middle lvs longer, relatively narrower, sts long and almost grasslike, 1, 2 or none of the lvs overtopping fl. Fl. solitary, ovary us. erect. Dorsal sepal c. 2.5–3.5–(4.5) cm. tall, often rather smoothly arcuate but sts erect below then horizontal above, acuminate to shortly caudate; lateral sepals diverging at a narrow angle, tips long-acuminate to caudate, sts considerably overtopping galea, or bent strongly backwards. Petals shorter than dorsal sepal, acute or acuminate. Labellum lanceolate-oblong, little arched, broad almost to middle then narrowing above to obtuse tip, the margins there ± deflexed and inclined to be pinched in. Column about as tall as labellum; stigma long-oval, often as broad as column, sts overlapped by wings from above.
