slender, straight, subterete, entirely concealed by close 
tubular imbricating sheaths, about 9-11 cm. long, join- 
ing at an obtuse angle beneath the pseudobulb where the 
rhizome is more or less branching. Pseudobulbs situated 
at the angles formed by the segments of the rhizome, 
complanate-ovoid, unifoliate at the apex, up to 2 cm. 
high, rugose-striate in the dried specimen, clothed at 
base by two pairs of imbricating conduplicate sheaths, 
the upper ones leaf-bearing. Leaves variable in size and 
shape, ovate-elliptic, lanceolate or elliptic-oblong, sharply 
acute or acuminate, sessile at the complicate base, up to 
8.4 cm. long and 3.4 cm. wide. Flowers small, solitary 
in the axils of bracts surrounding the pseudobulbs, sub- 
sessile, reddish with a cream-colored lip. Sepals and 
petals subparallel, rather fleshy. Dorsal sepal lanceolate 
or oblong-lanceolate, acuminate, concave, about 10 mm. 
long and 8 mm. wide. Lateral sepals obliquely and nar- 
rowly triangular-lanceolate, shortly acuminate, about 
10 mm. long on the posterior margin, forming with the 
column-foot a mentum about 4 mm. long. Petals ob- 
lanceolate-linear, acute, lightly concave above, about 8.9 
mm. long and 1.8 mm. wide. Lip slightly shorter than 
the sepals, lightly recurved in natural position, sharply 
3-lobed with the lateral lobes incurved to form a tubular- 
involute basal portion, oblong-spatulate when forcibly 
expanded, lightly retuse in front, about 9.5 mm. long 
in the middle and 6.1 mm. wide above; lateral lobes 
small, linear-oblong, with the short free apex porrect, 
ovate-oblong, obliquely rounded and obscurely denticu- 
late at the apex and about 1.6 mm. long; mid-lobe much 
larger than the lateral lobes, round-obovate, cuneate be- 
low, broadly rounded above, retuse, with crenulate-erose 
margins, fleshy-thickened above in the middle, about 6.8 
mm. long; dise thickened below, with the thickening 
terminating in a subquadrate retuse callus between the
