gine longe ciliata, superne prope marginem longe gland- 
uloso-hirsuta. Sepalum dorsale anguste lanceolatum, a- 
piculatum, acutum, extus per medium carinatum, intus 
ralde pilosum. Petalaminuta, lanceolata, uninervia,acuta, 
margine fimbriata. Labellum anguste lanceolatum, acu- 
tum, superne dense papillosum, prope basim breviter bi- 
-arinatum, margine dense fimbriato. Columna alata,apice 
irregulariter dentata, rostello trifido permagno instructa. 
Epiphytie herb. Roots coarsely fibrous, whitish, 
glabrous. Secondary stems monophyllous, 14-19 em. 
long, slender, about 2 mm. in diameter when dry, with 
a closely appressed elongated tubular sheath near the 
base and with one or more short tubular scarious sheaths 
near the rhizome, but otherwise the secondary stems are 
naked and smooth. Leaf terminating the stem, 9—-14.5 
em. long, about 2 cm. wide, coriaceous,oblong-lanceolate, 
acuminate, acute. Peduncles one to three, successive, in 
the axil of the leaf, issuing from a short spathe-like bract, 
ascending or strongly arcuate, 5-7 em. long, each pe- 
duncle with a short tubular closely appressed sheath near 
the base. Raceme 5-6.5 cm. long, about 7—flowered, 
more or less curved or drooping. Bracts of the raceme 
tubular at base, acuminate, smooth, exceeding the pedi- 
cels. Flowers 10-12 mm. apart. Pedicel and ovary about 
5 mm. long, obliquely ascending, smooth. Lateral sepals 
12-18 mm. long, coherent throughout their length form- 
ing a strongly convex elliptical lamina 8 mm. wide, and 
conspicuously bicarinate on the outer surface with each 
‘arina decurrent on the ovary forming a conspicuous 
wing; sepaline lamina smooth on the outer surface, con- 
spicuously glandular-hairy near the margin on the inner 
surface. Dorsal sepal up to 17 mm. long, about 3 mm. 
wide, narrowly lanceolate, apiculate-acute,carinate along 
the mid-rib on the outer surface with the carina decurrent 
on the ovary, glandular within and with long @landular
