CENTRAL AMERICAN ORCHIDS 
umnae adnatum, simplex, suborbiculare, basi cordatum. 
Columna brevis. 
Stems about 4 mm. in diameter, branched, rooting. 
Leaves distichous, 8-12 cm. long, up to 2.5 cm. wide, 
narrowly elliptic-oblong, rounded at base, gradually nar¬ 
rowed toward the acute or obtuse tip, rigid, jointed to 
rigid closely oppressed complanate sheaths, the leaves 1-2.5 
cm. apart. Inflorescence terminal. Flowers light viridine- 
yellow (Ridgway) when fresh, distichous in short racemes, 
the subtending bracts exceeding the pedicellate ovary. 
Raceme 2.5 cm. long, about 2 cm. across, few-flowered, sub¬ 
tended by seven or more closely imbricating complanate 
sheathing bracts which are 11-16 mm. long. Floral bracts 
about 12 mm. long, glumaceous. Pedicel with the ovary 
about 7 mm. long, wholly concealed by the subtending floral 
bract. Lateral sepals 1 cm. long, 3 mm. wide, narrowly 
elliptic-oblong, terminating in a blunt thickened tip, the 
three central nerves much thickened in dried specimens. 
Dorsal sepal about 1 cm. long, oblong, obtuse. Petals about 
1 cm. long, 4 mm. wide above the middle, spatulate, obtuse, 
the nerves thickened. Labellum adnate to the column, in¬ 
cluding the adnate base 1 cm. long, up to 8 mm. wide, sub- 
orbicular-cordate, obtuse. Disc tricarinate, the middle keel 
extending to the tip of the labellum. Column 3 mm. long, 
with the clinandrium entire. 
Undoubtedly a close ally of Epidendrum phyllocharis 
Reichb. f., from which it differs in being ecallose at the base 
of the labellum and in having the pedicellate ovary of each 
flower entirely concealed by an ample imbricating bract.
