TROPICAL AMERICAN ORCHIDS 
dunculi leviter fractiflexa, plus minusve septemflora. Brac- 
teae racemi infundibuliformes, acutae. Pedicellus cum 
ovario bracteis longior. Sepala oblongo-lanceolata, acuta, 
apicibus incrassata. Petala linearia, plus minusve in- 
crassata. Labellum trilobatum; lobis lateralibus rotun- 
datis; lobo medio lineari. Discus lamella denticulata or- 
natus. Columna brevis, lamellae disci adhaerens. 
Rhizome very slender, copiously rooted. Roots very 
much branched, finely fibrous, spreading, elongated, whitish, 
smooth. Stems 9-15 cm. long, probably decumbent, less 
than 1 mm. in diameter, flexuous. Leaves six to eight, dis¬ 
tichous, 1.5-3 cm. long, hardly .5 mm. wide when dry, su¬ 
bulate, acute, 9-14 mm. apart, obliquely ascending. In¬ 
florescence terminal. Peduncle with the raceme 3.5-5 cm. 
long, slender. Rachis of the raceme slightly zigzag, bearing 
about seven small flowers. Bracts of the raceme 2.5-3.5 
mm. long, infundibuliform below the middle, narrowed 
above into a triangular acute tip. Pedicel with the ovary 
longer than the subtending bract. Lateral sepals 4.25 mm. 
long, 1.5 mm. wide, sharply reflexed, lanceolate, acute, cari- 
nate-thickened near the tip, convex. Dorsal sepal 4 mm. 
long, 1.5 mm. wide, oblong-lanceolate, acute, carinate- 
thickened beneath the tip. Petals 3.5-4 mm. long, .5 mm. 
wide, linear, subacute, triquetrously thickened from about 
the middle to the apex, spreading or obliquely porrect. La¬ 
bellum about 4 mm. long, adherent to the column, 3-lobed, 
fleshy, about 3 mm. wide across the lateral lobes; lateral 
lobes 1.5 mm. long, rounded in front, ascending, together 
forming an orbicular lamina; middle lobe 2 mm. long, .5 mm. 
wide near the base, porrect, linear, gradually narrowed to 
the subacute tip, semiterete. Disc of the labellum smooth, 
but with a conspicuous horizontally placed plate at the base 
which is adherent to the column, and denticulate or crenulate 
in front. Column stout, 1.25 mm. long. 
A close ally oi Epidendrum paranihicum Reichb. f., from 
which it differs in having larger flowers and a very different 
lamella on the disc beneath the apex of the column. From 
E. musicolum Schltr., -— a species which I have not seen and 
know only from the description, — it differs in having nar-
