Epichile convex, when flattened circular to elliptic, 0.5-0.75 by 0.35-0.9 cm, with a broad, short claw 0.015-0.02 cm thick; base broadly attached over 0.3-0.75 cm; apex acute, slightly raised, with an obtuse apex; margin slightly elevated, recurved; sides pronounced as lateral lobes, without warts, centre 0.015-0.02 cm thick, margin 0.01-0.03 cm thick; keels 3, ending 0.31-0.55 cm from the apex of the epichile, on the claw identical with the ornamentations on the hypochile, on the blade sometimes changing into a row of tightly packed irregularly rounded warts c. 0.1 cm high, with papillae but without hairs.

(After Gravendeel and De Vogel, 1999).
