Plant probably always epiphytic, up to 39 cm. tall, 
much branched, often fruticose. Primary stem often con¬ 
spicuously thickened and reaching 3.5 mm. in diameter in 
the lower part. Branches short or elongate and commonly 
much branched; the internodes mostly concealed by the 
densely verruculose, closely oppressed leaf-sheaths. Leaves 
linear or more rarely lanceolate-linear, very variable in size, 
about 1.2-6.2 cm. long, 2-6 mm. wide, abruptly and often 
obliquely bilobed at the apex, distichous, coriaceous. Ra¬ 
cemes terminal on the branches, loosely 2- to 7-flowered; 
rachis commonly fractiflex, smooth, up to 3 cm. long. Floral 
bracts concave, ovate, acute, up to 7 mm. long, generally 
equaling the pedicellate ovary, scarious in the dried spec¬ 
imens. Perianth parts rigidly spreading. Lateral sepals 
obliquely oblong-lanceolate or elliptic-lanceolate, acuminate, 
b-8 mm. long, 2-3.2 mm. wide, apex carinate-thickened, 
5- to 7-nerved. Dorsal sepal lanceolate-oblong, 5-8 mm.

Epidendrum Sanchoi is a member of a closely allied group 
'Which includes E. microcardium Schltr., E. microdendron 
Peichb. f., E. rugosum Ames and E. trachythece Schltr. E. 
microcardium and E. trachythece differ markedly from this 
species in their smaller flowers and dissimilar lip. E. micro-
