Rhizome 5-8 mm diam., sections between pseudobulbs 3-12.5 cm long, bract fibres rather thick, persistent. Pseudobulbs ovoid, 1-4 by 0.8-1.5 cm. Petiole 1-4.5 cm. Leaf blade elliptic to obovate, 10-26 by 2.8-7 cm, index (length/width) 2.4-5.5; obtuse. Flowers moderately to widely opening. Median sepal recurved to spreading, often with incurved top part, ovate to triangular, 20-38 by 5-10 mm, index 2.2-4.8; acute to shortly acuminate, base rather widely attached. Lateral sepals free, recurved but somewhat converging towards the tip, top part somewhat curved inwards, 17-32 by 6.5-12 mm, index 1.9-3.2; base widely attached; otherwise as the median sepal. Petals recurved to reflexed, sometimes with incurved top part, elliptic to (ob-)ovate, 18-30 by 4-9.6 mm, index 2-6; acute to shortly acuminate, base rather narrowly attached. Lip recurved in the proximal half, triangular with a drawn-out, linguiform and slightly widened top part, 9-16.5 by 2.5-5 mm, index 2.6-6 (all without artificial spreading); truncate to obtuse, margins folded into two retrorse, thick, + straight, horn-shaped projections above the base when the lip is observed in lateral view; thick; adaxially concave in between the horns, convex towards the tip; abaxially with a rounded ridge up to about 1/2 of the length of the lip, top part often slightly concave. Column 4-6.5 mm long, c. straight in profile, stigma without teeth at the base; column foot without ridges in the proximal half. Stelidia porrect, triangular, 1-1.8 mm long, rounded to obtuse, without tooth along the lower margin. (After Vermeulen, ms.)
