omnino obtecti. Folium ellipticum, subacutum vel ob- 
tusum, basi in petiolum perbrevem angustatum. Inflores- 
centiae unicae vel duae, folia valde superantes. Racemi 
laxe pluriflori. Pedicelli longi, arcuati vel patentes. Flores 
parvi. Sepalum dorsale lanceolatum, longe acuminatum, 
concavum, trinervium, dorso carinatum. Sepala lateralia 
fere libera, triangulari-linearia, uninervia, dorso carinata. 
Petala multo minora, oblique elliptico-lanceolata, acuta 
vel acuminata, uninervia. Labellum lanceolatum, infra 
medium obscure trilobatum, antice in apicem obtusum 
angustatum; discus basi incrassatus. Columna gracilis, 
pedata. 
Plant small, caespitose, about 6 cm. tall. Roots fi- 
brous, glabrous, long for the plant. Stems short and slen- 
der, simple, spreading, monophyllous, entirely clothed 
with sheaths, up to 8 cm. long, often with a decumbent 
base. Cauline sheaths five or less, lepanthiform, minutely 
scabrous along the longitudinal nerves, infundibuliform 
above with a flaring marginate hispidulous mouth. Leaf 
elliptic, subacute to rounded above with a minutely tri- 
denticulate apex, in the dried specimen shortly petioled 
at the broadly cuneate base, up to 2.7 cm. long and 9 
mm. wide, thickly coriaceous. Inflorescences one or two, 
arising just below the joint of the leaf, capillary, much 
surpassing the leaf, arcuate, up to 5 cm. long (including 
the flowers), loosely few- (up to 10-) flowered. Pedicels 
arcuate or spreading, much exceeding the minute infun- 
dibuliform floral bracts. Flowers small but large for the 
plant; segments little spreading. Dorsal sepal lanceolate, 
concave below, rather abruptly long-acuminate above, 
about 7 mm. long and 2.8 mm. wide near the base, 8- 
nerved, dorsally carinate especially through the lower 
part with the keel produced onto the ovary. Lateral se- 
pals triangular-linear or lanceolate-linear, free nearly to 
the base, about 7.2 mm. long and 1 mm. wide at the
