TROPICAL AMERICAN ORCHIDS 
sale lanceolatum, acuminatum, acutissimum, trinervium 
nervis prominentibus, extus sparse glandulosum. Petala 
lineari-lanceolata, leviter falcata, utrinque attenuala, acuta, 
trinervia. Labellum columnae adnatum, simplex; lamina 
transverse elliptica parte terminali triangulari, acuta. Dis¬ 
cus per medium nervis incrassatis approximatis instructus. 
Golumna carnosa, apice edenticulata. 
Rhizome creeping, rooting, elongated, slender, 1-2 mm. 
in thickness. Stems 2.5-4 cm. long, slenderly fusiform, 
8-11 mm. apart on the rhizome, 2-3 mm. in diameter when 
dry, clothed (when immature) with several loosely oppressed 
sheathing bracts, the uppermost one leaf-like, monophyllous 
or subdiphyllous. Leaf 6-8 cm. long, 2-2.5 mm. wide, linear, 
obtuse, margin more or less revolute in dried specimens. 
Peduncle terminal, including the raceme about 2 cm. long, 
few-flowered. Raceme about 1 cm. long, loosely flowered. 
Pedicel with the ovary about 3 mm. long, densely glandular, 
with the glands abbreviated and rufous. Floral bracts 
shorter than the ovary, linear-lanceolate. Lateral sepals 
5.5 mm. long, about 2 mm. wide, asymmetrically lanceolate 
or lightly falcate, acuminate, acute, prominently nerved, 
sparsely and shortly glandular on the outer surface, es¬ 
pecially on the nerves. Dorsal sepal about 6 mm. long, 
1.25 mm. wide, lanceolate, acuminate, acute, sparsely 
glandular on the outer surface. Petals 5 mm. long, .5-.75 
mm. wide, linear-lanceolate, lightly falcate, acute, 3-nerved. 
Labellum with the base adnate to the column, 5 mm. long; 
lamina 3.5 mm. long, about 3 mm. wide, somewhat concave, 
lower two-thirds transversely elliptic, upper third narrowly 
triangular and acute. Disc prominently 3-nerved along the 
middle with the nerves approximate. Column hardly 3 mm. 
long, stout, with the fleshy clinandrium entire. 
Epidendrum glandulosum is without close allies in the 
Central American flora. It suggests the Cuban E. vestilum 
Ames, but it differs from that species in the normally 
monophyllous stems, glandular ovary and sepals, and in the 
absence of calli at the base of the labellum. [Plate 20: 1,
