Plant c. 3–10 cm. tall at fl. Stem short, erect, smooth, us. half hidden by lvs until part below ovary elongates at fr. Lvs us. 2–3, all much alike, often equalling and sts overtopping fl.; lamina c. 3–6 × (1)–1.5–2.5 cm., orbicular to broad-oval, tip obtuse to broadly subacute, base narrowing to broadly winged, sheathing petiole. Fl. solitary; ovary us. erect. Dorsal sepal c. 1.5 cm. tall, erect then horizontal, acute to very shortly acuminate; lateral sepals diverging at a narrow angle, tips acuminate to shortly caudate, not greatly overtopping galea. Petals almost as long as dorsal sepal, broad almost to tip. Labellum narrow-triangular, arched and protruding, apex subacute, inner surface quite covered with short retrorse hairs giving an unusually furry appearance. Column us. shorter than labellum; stigma narrow-elliptic.
