Hypochile when flattened triangular or elliptic in outline, median somewhat swollen and there with fine papillose warts; lateral lobes large, far projecting in front, mostly pointing forward, sometimes outward, projecting part rounded, 0.3-0.6 cm long, top sometimes ciliolate. Epichile subquadrate to elliptic, 0.8-1.1 by 0.5-0.9 cm, centrally swollen and there with irregular warts, sometimes with cross-bands; base not constricted; margins undulate, sometimes ciliolate; top usually acuminate. Column about lanceolate when flattened, 1.3-2.0 by 0.15-0.25 cm, sometimes dorsally with a strong median rib; seams 0.08-0.15 cm wide, to the top narrowing; top hood-like, 0.15-0.2 cm high; rostellum triangular, about as big as the anther.
