ORNITHOCEPHALUS POLYODON 
Ornithocephalus polyodon Reichenbach filius in 
Linnaea 41 (1876) 33. 
Since this species, originally found in Ecuador, was 
described from two inflorescences only, it seems wise to 
append a more detailed description as afforded by a recent 
Peruvian collection consisting of three complete plants. 
Plant rather large and stout for the genus, epiphytic, 
about 11-19 cm. tall. Stems abbreviated as in the genus, 
entirely concealed by a circle of nine to eleven crowded 
imbricating sheaths of the leaves. Leaf-sheaths condu- 
plicate with a scarious band on the upper margin. Leaves 
elliptic-lanceolate to linear-lanceolate, more or less acu- 
minate, usually lightly oblique above, somewhat nar- 
rowed to an obliquely articulated base, about 3 (outer 
blade) -16 cm. long, 0.85—-1.4 cm. wide. Scapes lateral 
in the axils of leaf-sheaths, usually two to each plant, 
suberect or flexuous to arcuate, about 9.5-19.5 cm. long, 
entirely glandular-setulose (slightly so below), racemose 
above; peduncle short, 4 em. or more long, with three 
or more remote, spreading, semiamplexicaul sheaths; 
raceme up to 14.5 cm. long, loose or subdense, several- (8) 
to many-flowered. Floral bracts spreading, suborbicular- 
ovate, semiamplexicaul, glandular-ciliolate. Flowers 
rather large for the genus, with membranaceous wide- 
spreading segments. Dorsal sepal deeply concave, sub- 
orbicular-obovate, broadly rounded at the apex, irregu- 
larly glandular-ciliate (especially on the lateral margins), 
rather densely glandular-setose on the outer surface, 1- 
nerved, about 6 mm. long and 4mm. wide. Lateral sepals 
oblong-obovate, broadly rounded above, lightly concave, 
somewhat oblique, sparingly serrate, rather densely 
glandular-setose without, 1-nerved and dorsally keeled,
