Lateral sepals wider than hood, shallowly concave, glabrous, margins strongly incurved, suddenly tapered into free points; free points tapered, 4– long, curved forwards, widely divergent. Petals with relatively small basal flanges, 11–14 x 3.5–5mm. Labellum broadly obovate, 4.5–6 x 2.5–3.5mm, dark brown, blunt, fleshy, shallowly channelled; marginal bristles 6–10, 1–3. long, basal pair most prominent; basal lobe thick, sloping backwards, with few small bristles.
