sepal oblong-oblanceolate, 1.19 cm. long, about 3.1 mm. 
wide above the middle, acuminate, 5-nerved. Petals elliptic- 
linear, 1.12 cm. long, somewhat oblique, acuminate, 3-nerved 
below the middle. Labellum adherent to the column up 
to its apex; lamina broadly sagittate-triangular, obscurely 
3-lobed, 6 mm. long, about 9.2 mm. wide across the base 
when spread out, the three middle nerves thickened at base; 
lateral lobes retrorsely spreading, obliquely triangular-lan¬

This description was prepared from dried specimens. 
Epidendrum triangulabium appears to belong to Sect. 
Acropleuranthium, as it has lateral as well as terminal in¬ 
florescences. It is without close affinities in Central America.

are specifically inseparable. The Costa Rican form, exempli¬ 
fied by E. baculibulbum, was set apart chiefly because of the 
long slender pseudobulbs, a character which is manifest in 
several specimens—from widely distributed areas—which 
are clearly referable to E. variegatum. 
Polystachya costaricensis Schltr. in Fedde Repert.

(1924) 31. 
A comparison of the type collections and descriptions 
of these species shows that they are inseparable, the only 
notable difference being that the flowers of P. costaricensis
