densissimus. Bracteae racemi scariosae, ovatae, conspicue 
nervosae. Flores extus valde glandulosi. Sepalum dor- 
sale ovato-oblongum, basi valde concavum. Sepala lat- 
eralia oblongo-lanceolata. Petala elliptico-linearia, sepalo 
dorsali valde adhaerentia. Labellum ovatum, apice ro- 
tundatum, basi late rotundata lateribus prope medium 
inflexis. Anthera magna, orbiculari-cordata. 
Plant terrestrial, tall, sigmoid-flexed in our specimen. 
Roots fasciculate, fleshy-thickened, about five in number, 
slender-fusiform, finely tomentose. Stem (including the 
raceme) about 105 em. in length, entirely concealed be- 
low by long very loose tubular scarious leaf-sheaths and 
above by short loose scarious imbricating sheaths. Leaves 
distant, confined to the lower and middle portions of the 
plant, merely withered remains at flowering time, imper- 
fect but apparently elliptic-lanceolate in our specimen. 
Raceme very dense, arcuate, 11.5 em. long but very im- 
mature above, about 2-8 cm. in diameter. Floral bracts 
scarious, ovate, sharply acuminate, with five prominent 
brownish nerves. Ovary and outer surface of sepals dense- 
ly glandular-pubescent. Flowers small for the plant. Dor- 
sal sepal strongly concave at the base, ovate-oblong, about 
11 mm. long, 4 mm. wide below the middle, acuminate, 
1-nerved or indistinctly 8-nerved. Lateral sepals connate 
with the dorsal sepal at the base, oblong-lanceolate, acu- 
minate, acute, about 10.2 mm. long, 2.7 mm. wide be- 
low the middle, slightly asymmetric at base and apex, 
indistinctly 8-nerved. Petals strongly adnate to the dor- 
sal sepal, elliptic-linear, little shorter than the dorsal se- 
pal, hghtly ineurved, acute, 1-nerved, about 1.5 mm. 
wide. Lip simple, ovate, subsessile, strongly involute on 
each side just above the middle, slightly undulate on the 
anterior margins, about 9 mm. long, 6.6 mm. wide near 
the base, rounded at the apex with an inconspicuous api- 
cule, broadly rounded and obscurely bicallose at the base;
