CENTRAL AMERICAN ORCHIDS 
7-nerved, the mid-nerve prominent in dried material. La- 
bellum about 1.5 cm. long, 3-lobed; lateral lobes much 
shorter than the middle lobe, 3 mm. long on the inner margin, 
2 mm. wide, lanceolate, obtuse; middle lobe including the 
isthmus 11 mm. long, about 8 mm. wide, rotundate, emar- 
ginate, heavily veined. Callus fleshy, very prominent (in 
dried specimens 2 mm. thick), shallowly excavated, oblong, 
extending beyond the base of the middle lobe, rounded in 
front, abruptly decurrent at the apex into three raised 
carinate nerves. Column 8 mm. long, very fleshy, produced 
on each side into a broad triangular acute wing, but not 
auriculate.

The prominent callus and large middle lobe, in com¬ 
bination with conspicuously smaller lateral lobes, give to 
the flowers of Epidendrum trachycarpum an aspect which is 
unusual in the genus. I only know this species through the 
material in Lindley’s herbarium at Kew. For the oppor¬ 
tunity to amplify Lindley’s brief description I am indebted 
to Captain Arthur W. Hill, Director of the Royal Gardens, 
Kew, who kindly submitted a flower of the type for ex¬ 
amination.

Reichenbach described two species under the name 
Epidendrum Porpax, one from Nicaragua in 1855 the other 
from Cuba in 1865. The Cuban species is without a valid 
name. The new name here proposed alludes to the ample 
sheaths which conceal the stems.
