Plant medium-sized, about 29 em. tall. Roots fibrous, 
glabrous, whitish, few. Stem stout, erect from a decum- 
bent base, entirely enveloped by loose scarious tubular 
sheaths which are imbricating and leaf-bearing except at 
the base, about 14 em. high (not including the decum- 
bent base). Leaves distichous, deciduous below, persis- 
tent near the apex of the stem, oblong-ovate or shortly 
oblong, ascending, subacute, up to 5 cm. long and 1.8 
em. wide, with a broad clasping base. Inflorescence much 
surpassing the leaves, suberect, loosely paniculate with 
few short ascending lateral branches, about 13.7 cm. 
long. Floral bracts lanceolate or linear-lanceolate, long- 
acuminate, spreading, up to 11 mm. long below, much 
shorter than the slender pedicellate ovary. Flowers small, 
numerous, loose, blackened in drying, with spreading 
perianth parts. Sepals fleshy, with strongly revolute 
sides. Dorsal sepal when expanded oblanceolate to nar- 
rowly obovate, acute with a dorsal mucro, prominently 
3-nerved or indistinctly 5-nerved, up to about 8.1 mm. 
long and 38.9 mm. wide when expanded. Lateral sepals 
obliquely oblong-oblanceolate or oblong-obovate, with 
the mucronate apex somewhat recurved, 3- to 5-nerved, 
up to 9 mm. long and 8.7 mm. wide. Petals linear- 
oblanceolate, acute, lightly oblique, 1-nerved, up to 7.8 
mm. long and 2 mm. wide. Lip adnate to the column 
up to its apex, convex, more or less deeply 3-lobed, 
broader than long, cordate at base, up to 4.4 mm. long 
from the center of the base to the middle of the mid-lobe 
and 6.6 mm. wide; lateral lobes ovate-semiorbicular with 
more or less lobulate margins; mid-lobe transversely sub- 
quadrate to irregularly semiorbicular, subtruncate to 
lightly retuse in front; dise bicallose at base. Column 
short, strongly dilated above in front, up to 5.5 mm. 
high at the back. 
Apparently this species lacks any close allies.
