base, up to 8.8 cm. long and 2 cm. wide (often much 
smaller), coriaceous, rigidly suberect, more or less im- 
bricating in the dried specimen. Inflorescence terminal, 
arcuate-flexuous, about 16 cm. long, paniculate with as- 
cending few- to several-flowered branches; rachis more 
or less fractiflex. Floral bracts spreading, ovate, acumi- 
nate, concave, slightly shorter than the pedicellate ovary. 
Flowers small, rather loose, numerous, fleshy, orange- 
red. Dorsal sepal elliptic-ovate, subobtuse, about 8.2 
mim. long and 5 mm. wide, 3-nerved. Lateral sepals ob- 
liquely and broadly ovate, acute, about 9.5 mm. long 
and 6 mm. wide, 3-nerved. Petals linear or oblanceolate- 
linear, obtuse, 1-nerved, about 7.8 mm. long. Lip adnate 
to the column nearly to its apex, slightly exceeding the 
lateral sepals ; lamina concave-conduplicate and surround- 
ing the apex of the column in natural position, simple, 
broadly ovate-cordate when expanded, deeply cordate at 
base, obtuse at apex, about 6.8 mm. long in the center 
and almost 10 mm. wide if forcibly expanded; dise with 
a pair of small fleshy complanate calli at base. Column 
stout, strongly dilated upward in front, terminating on 
sach side in a very oblique transverse retuse auricle, 
about 5.2 mm. long at the back. 
Epidendrum aquaticoides is very suggestive of the Bra- 
zilian £7. aqguaticum but differs in having a stout subsimple 
stem, numerous leaves, almost twice larger orange-red 
(instead of greenish or yellowish) flowers and the disc of 
the lip bicallose at base.
