superantes, laxe pluriflori. Bracteae conspicuae, atropur- 
pureae. Flores pro planta magni, glabri, plani. Sepala 
late triangulari-ovata, obtusa vel subacuta, tri- vel quad- 
rinervia. Petala multo minora, suborbiculari-ovata, valde 
carnosa. Labellum petalis minus, ovato-semiorbiculare, 
apice obtusum vel rotundatum, concavum, mediana cum 
carina transversa bilobata. Columna generis. 
Plant small, caespitose, up to 12.3 cm. high to the tip 
of araceme. Rhizome abbreviated. Roots fibrous, fili- 
form, glabrous. Stems very slender, 1-leaved at the apex, 
about 8.6 cm. or less tall, concealed by three close tubu- 
lar sheaths which are imbricating, dark or maculate and 
evanescent. Leaf erect, indistinctly petioled, 3.2-6.1 cm. 
long, 3.5-9 mm. wide; lamina elliptic-oblong or oblan- 
ceolate-oblong, minutely tridenticulate at the subacute 
apex, gradually cuneate below, chartaceous, up to 5.3 
em. long. Racemes axillary, one to nine, more or less 
surpassing the leaf, erect to arcuate or diffuse, loosely 
4- to 13-flowered above, about 10 cm. or less long. Floral 
bracts infundibuliform, acuminate, widely spreading, 
apparently blackish purple. Flowers large for the plant, 
apparently flat, rounded-triangular in outline, pale green- 
ish white, glabrous, with the sepals deeply connate _be- 
low. Dorsal sepal triangular-ovate, obtuse or subacute, 
3- or 4-nerved, about 4.1 mm. long and slightly wider 
near the base of the free portion. Lateral sepals closely 
similar to the dorsal sepal but slightly shorter, suboblique, 
3- or 4-nerved, about 3.5 mm. long and 4.1 mm. wide 
across the free portion, strongly obtuse. Petals much 
smaller than the sepals, suborbicular-ovate, rounded 
above, 8-nerved, lightly cordate at base, with all except 
the basal part fleshy-thickened, about 1.3 mm. long and 
markedly wider below. Lip smaller than the petals, 
ovate-semiorbicular, obtuse to rounded at the apex, con- 
cave, with a prominent fleshy transverse bilobed callus
