TROPICAL AMERICAN ORCHIDS 
14-20 cm. long, 3-4 cm. wide, oblong or elliptic-oblong, 
coriaceous, bilobed at the rounded apex, obliquely ascend¬ 
ing. Inflorescence terminal, up to 13-tlowered. Peduncle 
with the raceme 23 cm. long, complanate, winged by the 
decurrent keels of the bracts, subtended at base by a con¬ 
spicuous conduplicate spathe. Bracts of the raceme about 
2-2.5 cm. long, strongly conduplicate, obliquely ascending, 
distichous, carinate along the middle with the keels decur¬ 
rent on the rachis. Pedicel with the ovary up to 2.5 cm. 
long, stout, hardly exceeding the floral bracts. Lateral 
sepals circinate, 1.4-1.5 cm. long, about 9 mm. wide, ovate- 
oblong, acute, with a short keel beneath at the tip, nerves 
somewhat prominent. Dorsal sepal 1.5 cm. long, about 
7 mm. wide, oblong-lanceolate, ecarinate beneath at the 
acute tip. Petals 1.4 cm. long, about 4 mm. wide, circinate, 
oblong, subobtuse, more membranaceous than the sepals. 
Labellum 3.1 cm. long to the base of the adherent column, 
1.7-2 cm. wide above the middle, free portion 2-2.5 cm. long, 
obovate, emarginate, with a central keel which is sometimes 
grooved along the upper surface. Column stout, about 
1 cm. long, produced on each side in front into a conical 
callus which is adherent to the disc of the labellum. 
Epidendrum circinatum is closely allied to E. palmense 
Ames and E. coriifolium Lindk, but is clearly separable from 
them by the strongly revolute or circinate sepals and 
petals, and by the very different labellum.
