 Description

Plant c. 7–16–(25) cm. tall at fl. Stem us. erect, smooth, internodes < lvs. Lvs mostly 2–4, the shape changing from below upwards; lamina c. 3–9 × 1–2 cm., broad- to narrow-elliptic; the lowest, and those on non-flowering rosettes, sts obovate, obtuse to subacute, narrowing to broadly winged petiole; uppermost us. somewhat shorter, acute to acuminate, almost or quite sessile, often reaching but rarely overtopping fl. Fl. solitary, ovary us. erect. Dorsal sepal c. 3 cm. tall, ± erect then horizontal to down-turned, very shortly acuminate; lateral sepals diverging at a narrow angle, tips acuminate to shortly caudate, not greatly exceeding galea and often turned outwards and backwards. Petals a little shorter than dorsal sepal, very broad almost to acute tip, the exposed lateral strip often rather wide and ± flaring outwards. Labellum elliptic, only slightly arched, tip narrowly obtuse. Column as tall as or often taller than labellum; stigma elongate, us. truncate and prominent at the top.
