sepals 21-24 mm. long, about 11 mm. wide, ovate-lanceolate, 
carinate-acute, the carina minutely serrate. Dorsal sepal 
about 22 mm. long, 6 mm. wide, strongly concave, cucullate 
near the tip below the rostriform apex. Petals about 17 mm. 
long, 2 mm. wide, linear-oblong, obtuse, 3-nerved, with the 
middle nerve prominent. Labellum adnate to the column, 
22 mm. long, 20 mm. wide, cordate-reniform, retuse. Disc 
traversed longitudinally by a fleshy prominence which termi¬ 
nates near the retuse apex of the lip in a carunculate callus. 
Column very fleshy, 13 mm. long. 
Allied with Epidendmm coriifolium Lindl., from which 
it differs in having broader leaves, and a carunculate callus 
near the apex of the labellum.
