lata, trinervia, intus plus minusve glandulosa, extus per 
medium unicarinata, apice breviter apiculata. Sepalum 
dorsale oblongo-lanceolatum, intus sparse glandulosum, 
extus per medium obscure unicarinatum, apice breviter 
apiculatum. Petala flabellata, valde carnosa, supra me- 
dium conspicue incrassata. Labellum linguiforme, valde 
incrassatum, utrinque obscure lobatum. Columna car- 
nosa, petala aequans. 
An herbaceous epiphyte 15-20 cm. tall with elon- 
gated racemes of dull purplish nodding flowers. Second- 
ary stems 5-10 cm. long, slender, densely caespitose, 
concealed by several elongated tubular sheaths, mono- 
phyllous. Leaves including the slender sulcate base 10-13 
em. long, about 1 cm. wide, coriaceous, narrowly oblong, 
tapering at base and narrowed toward the apex, bilobu- 
late with an apicule betwe -n the lobules. Raceme 11-16 
em. long, slightly exceedii.y the leaf. Peduncle sheathed 
at base by a conduplicate, acute sheath which is 12 mm. 
long and about 4 mm. wide when spread out. Bracts of 
the raceme about 2 mm. long, 4 mm. apart, or the lower- 
most ones almost contiguous, obliquely infundibuliform, 
equalling the pedicels of the nodding flowers. Pedicels 
about 4mm. long, smooth. Flowers twenty-five to fifty, 
vinous-purple when dry. Lateral sepals about 4.5 mm. 
long, 2 mm. wide below the middle, ovate-lanceolate, 
apiculate, sparsely glandulose on the inner surface, 3- 
nerved, on the outer surface distinctly carinate along the 
mid-nerve. Dorsal sepal 6 mm. long, 2 mm. wide, oblong- 
lanceolate, apiculate, 3-nerved with the middle nerve 
lightly if at all carinate. Petals scarcely 1 mm. long, 1 
mm. wide, flabellate, much thickened above the middle, 
1-nerved. Labellum 1 mm. long, about 0.5 mm. wide, 
linguiform with an obscure acute lobule on each side near 
the middle, 3-nerved, quadrate-thickened below the mid- 
dle, minutely glandulose near the base, lightly concave
