Labellum carnosum, spathulatum, obtusum, margine supra 
medium inaequaliter dentatum, infra medium labelli utrin- 
que unidentatum vel unilobulatum; lobulis triangularibus, 
acutis, erectis, porrectis, apice lobulorum medium labelli 
excedentibus. Discus glaber, supra medium utrinque 
breviter bicarinatus, trinervius. Columna carnosa, apice 
paucidenticulata. 
Secondary stems 4-20 cm. long, with elongated brown¬ 
ish sheaths at the base, triangular with a groove between 
each angle, monophyllous, somewhat dilated above. Leaf 
8-10 cm. long, 1.5-2 cm. wide, narrowly elliptic-lanceolate, 
very coriaceous, bidenticulate at the tip with a short apicule 
between the teeth, narrowed below and passing imper¬ 
ceptibly into the dilated summit of the secondary stem. 
Peduncles congested in the axil of the leaf, clothed with 
several infundibuliform bracts, with the 4-flowered raceme 
about 1 cm. long, stout, sheathed at base by an ample 
spathaceous bract. Pedicel with the ovary 2.5-3 mm. long, 
stout, subtended by infundibuliform bracts. Lateral sepals 
at first coherent nearly to the tip, becoming free to the base, 
6 mm. long, 2 mm. wide, oblong-lanceolate, acute, very 
fleshy, traversed longitudinally — along the middle of the 
outer surface — by a minutely scabridulous keel, margin 
obscurely glandulose. Dorsal sepal 6.5 mm. long, 2.5 mm. 
wide, oblong, subacute, very fleshy, minutely glandulose on 
the margin and outer surface, carinate. Petals 3 mm. long, 
1 mm. wide, oblong, terminating in a slender acumen, 
3-nerved, the margin of the upper half minutely and ir¬ 
regularly denticulate. Labellum very fleshy, 4 mm. long, 
1.5 mm. wide above the middle, spatulate, with a triangular 
acute lobe on each side 1.5 mm. above the base, margin of 
the upper half conspicuously dentate, the lower teeth larger 
than the upper ones and curved sharply forward; lobules 
1 mm. long. Disc smooth, 3-nerved, with a short keel on 
each lateral nerve near the middle. Column 4 mm. long, 
produced into an abbreviated foot at base, apex minutely 
and unequally denticulate or tridentate. 
This species is very closely allied to Pleurothallis sicaria 
Lindl., a native of Trinidad. At first glance I mistook the
