ovate, squarrose. Flowers small, subfleshy, mignonette 
and flesh-red, with spreading segments. Sepals acute, 
d-nerved. Dorsal sepal obovate-elliptic, up to 7.6 mm. 
long and 3.8 mm. wide. Lateral sepals obliquely elliptic- 
obovate, about 8 mm. long and 4 
mm. wide. Petals oblanceolate- 
linear, subacute to retuse, lightly 
falcate, up to 7 mm. long and 1.3 
mm. wide, 1- or obscurely 3- 
nerved. Lip adnate to the column 
nearly to its apex; lamina fleshy, 
transversely oval in outline, ab- 
ruptly bilobulate in the middle 
with two semiorbicular lobules, 
Epidendrum rectopedun- 
broadly rounded on each side, — culatum, flower, expanded, 
three times natural size. 
subtruncate-cuneate at the base, 
up to 7 mm. long on either side of the center and 12.8 
mm. wide; disc with a pair of subglobose calli at the base 
and three to five more or less distinct fleshy ridges in 
front. Column short and stout, gently dilated upward in 
front, up to 4 mm. long, truncate at the irregular apex. 
Ovary with a semiellipsoid vesicle. 
Lpidendrum rectopedunculatum is closely allied to the 
Central American 7. pachyrachis Ames, but differs in 
having larger leaves, in having an erect long-peduncled 
inflorescence which is provided with several remote short 
branches, in its dissimilar petals and in the absence of a 
sharp apicule in the center of the lip. This concept ap- 
pears to be so similar to #7. pachyrachis, however, that, 
with the aid of more material of either species, it may be 
found specifically inseparable.
