extus dense pubescentibus et labelli basi cum lobulis 
parvis dentiformibus a specie differt. 
Plant epiphytic, medium-sized to large, apparently 
with a creeping rhizome. Stems unifoliate, 6-27 cm. 
long, with two or three close, tubular, evanescent sheaths 
near the base. Leaf erect, oblong-elliptic, subacute, cu- 
neate at the sessile base, 9-14 cm. long, up to 3.5 cm. 
wide. Inflorescences one or two (perhaps more), abbre- 
viated, nodding, densely few-flowered. Flowers small, 
finely short-pubescent without, bilabiate, brownish yel- 
low somewhat ‘“‘striped with darker brown-yellow.”’ 
Dorsal sepal narrowly oblong-lanceolate, acute and mu- 
cronate, up to 9.4 mm. long and 2.2 mm. wide, 3- to 
5-nerved. Lateral sepals connate into an elliptic-lanceo- 
late, sharply bidentate lamina which is about as long as 
the dorsal sepal but nearly twice as wide. Petals much 
smaller than the sepals, elliptic-lanceolate, short-acumi- 
nate, serrate above, about 4 mm. long and 1.2 mm. wide 
near the middle. Lip smaller than the petals, lightly 
arcuate below, ovate-oblong, rounded at the apex, tri- 
lobulate above the cuneate base with a pair of small, 
erect, dentiform, obtuse lateral lobes, bicarinate through 
the middle, about 2.2 mm. long. Column about as long 
as the lip, abruptly dilated above. 
This variety of a widespread species is commonly dis- 
tinctly larger than the type and has very short inflores- 
cences. Moreover, the flowers are densely pubescent 
without, and the lip has short but distinct lateral lobules.
