lateralia profunde connata, quam sepalum dorsale brevi- 
ora et latiora, suborbiculari-ovata. Petala multo minora, 
transverse ovalia, apice leviter incrassata et late rotun- 
data. Labellum petalis subaequale, late triangulari- 
ovatum, incrassatum. Columna generis. 
Plant medium-sized, slender. Roots fibrous, filiform, 
glabrous, long. Rhizome ascending, slender, concealed 
by tubular evanescent sheaths, bearing remote scattered 
roots throughout. Stems strongly ascending, subapprox- 
imate to 1.5 cm. apart, slender, about 7.6-9 cm. long, 
with three rather loose tubular sheaths of which the 
uppermost is largest and separated from the others. Leaf 
solitary, petioled, up to 9.4 cm. long; lamina narrowly 
elliptic-oblong (rarely oblong), 6-8 em. long, 9-13 mm. 
wide, acute with a minutely tridenticulate apex, cuneate 
below, chartaceous, with the mid-nerve rather promi- 
nently exserted beneath. Racemes solitary or rarely two, 
much surpassing the leaf, subdensely many-flowered 
(looser below), suberect to flexuous, with the flowers 
secund in anthesis, about 18-17 cm. long. Floral bracts 
small, infundibuliform, spreading, acute or apiculate. 
Flowers small, membranaceous, bilabiate, glabrous. Se- 
pals 3-nerved, connate at base. Dorsal sepal elliptic-ovate, 
subacute, concave, about 3.5 mm. long and 2.25 mm. 
wide when expanded. Lateral sepals connate to the mid- 
dle or above, deeply concave, suborbicular-ovate, slightly 
oblique, subacute to obtuse, about 2.75 mm. long and 
2.5 mm. wide when expanded. Petals much smaller 
than the sepals, transversely oval, 3-nerved, broadly 
rounded and somewhat fleshy-thickened above, about 
0.6 mm. long and 1 mm. or more wide. Lip subequaling 
the petals, broadly triangular-ovate, concave, subacute 
or obtuse, truncate-subcordate at base, about 0.75 mm. 
long and 1 mm. wide; dise mostly occupied by a fleshy 
thickening which is highest and convex (in profile) in the
