TROPICAL AMERICAN ORCHIDS 
Epidendrum adnatum A. & S. sp. nov. Planta Epi- 
dendrum Lankesteri valde revocans. Caulis in parte basali 
nudus, complanatus, vaginis distichis omnino inclusus. Fo¬ 
lia pauca, lineari-lanceolata, longe acuminata. Pedunculus 
bialatus. Inflorescentiae breves, interdum trifurcatae. Se- 
pala lateralia oblique oblanceolata. Sepalum dorsale oblan- 
ceolatum. Petala fdiformia. Labellum apici columnae gra¬ 
cilis affixum, ovatum. 
Plant 36 cm. or less tall, the stem apparently rising from 
a creeping rhizome. Roots few, scattered, fibrous, flexuous, 
glabrous, longitudinally sulcate when dry. Stem, com- 
planate, leafless below, entirely invested with imbricating 
sheaths of which the middle and upper ones are longitudi¬ 
nally striate in the dried specimen. Leaves few, distichous, 
linear-lanceolate or linear-elliptic, 11-21.5 cm. long, 9.5-14 
mm. wide (the lowermost and uppermost blades have the 
smaller dimensions), very long-acuminate above, gradually 
cuneate-narrowed below, many-nerved, chartaceous, up to 
3.7 cm. apart in the middle of the stem (closer above), 
ascending. Peduncle below the inflorescence reaching 9.3 
cm. long, strongly complanate, bialate especially below, 
2- 3 mm. wide across the lower portion. Inflorescences 4 cm. 
or less long, consisting at maturity of a short very strict 
3- branched panicle at the summit of a long naked peduncle 
or of a long-peduncled panicle supplemented by an abbre¬ 
viated short-peduncled 2-branched panicle—the two ter¬ 
minal, but enclosed at base by the sheath of the uppermost 
leaf. Bracts approximate or imbricate, conduplicate, sca- 
rious and striate-nervose when dry; the lowermost bract 
of the long-peduncled inflorescence narrow and elongated 
(1.75-2.15 cm. long). Flowers medium-sized. Lateral sepals 
narrowly oblanceolate, very oblique, 1.22 cm. long, about 
2.85 mm. wide above the middle, acute, mucronate on ac¬ 
count of an apical keel, 5-nerved. Dorsal sepal oblanceolate, 
1.2 cm. long, about 3 mm. wide above the middle, acute, 
5-nerved. Petals fdiform, 1.22 cm. long, 1-nerved. Labellum 
simple, base adnate up to the apex of the column; lamina 
relatively small, ovate, about 5.4 mm. long, about 4.2 mm. 
wide below the middle, abruptly apiculate. Disc with a pair
