obtectus. Folia pauca, filiformia, subteretia. Inflorescen- 
tiae terminales, racemosae, laxe pluriflorae. Flores per- 
parvi, subglobosi, carnosi. Sepalum = dorsale ovatum, 
mucronatum. Sepala lateralia oblique lateque ovata, 
valde acuta et mucronata, dorso carinata. Petala linearia, 
acuta, supra paulo latiora. Labellum colummae valde ad- 
natum ; lamina parva, ovato-cordata, subacuta, conspicue 
bicallosa. Columna pro flore magna et crassa, apice utrin- 
que subquadrato-auriculata. 
Plant small, slender, epiphytic, arcuate. Roots fibrous, 
filitorm, Hexuous, elongate. Stems slender, about 25 em. 
or less long including the raceme, provided with numer- 
ous short branches, wholly concealed (as are the branches) 
by close tubular evanescent sheaths which are leaf-bearing 
on the upper part of the branches, the main stem often 
with short adventitious roots at the junction of the 
branches. Leaves one to four to a branch, distichous, sub- 
terete, filiform, up to 5.8 em. long, abruptly acute or apic- 
ulate, ascending or spreading. Inflorescence a terminal 
raceme about 4.5 cm. or less long, with the peduncle 
more or less concealed by a slender conduplicate scarious 
spathe. Raceme rather short, loose, up to 11-flowered. 
Flowers very small, little open, subglobose-ellipsoid, 
greenish white. Sepals fleshy, concave, 3-nerved. Dorsal 
sepal ovate, about 8.5 mm. long and 2.2 mm. wide, acute 
with a dorsal mucro. Lateral sepals slightly larger than 
the dorsal sepal, obliquely broad-ovate, sharply acute 
and mucronate, dorsally carinate, shortly connate below, 
about 8.8 mm. long and 2.2 mm. wide. Petals linear, 
acute, I-nerved, about 8 mm. long and 0.5 mm. wide 
above the middle, slightly dilated at the base. Lip adnate 
to the column nearly to its apex: lamina small, cordate- 
ovate, fleshy, concave, subacute, about 1.9 mm. long from 
a basal auricle to the apex and nearly as wide across the 
base; disc at base with a pair of relatively large fleshy
