with two buds. We are at a loss to understand how Achille 
Richard indicated two to three fiowers. 
Rhizome creeping, with membranous, nervose, dense sheaths. 
Roots very numerous, thin, bent and flexed, beautifully green 
when young. Secondary stems with few narrow sheaths, tri- 
gonous, at length with five or three furrows. Leaf cuneate- 
ligulate, with three very sharp teeth at the apex, nearly trigonous ; 
the side teeth of the leaf are sometimes obliterated. Flowers one 
to three, very thickish, bivalvate, bright cinnabar-red. The 
superior sepal oblong-ligulate or ligulate, apiculate, now with 
minute papille on the sides, three-nerved ; side sepals connate, 
very broad, sometimes oblong or nearly quadrangular, bifid at 
the tip or only bidentate, with keels over the middle nerves out- 
side. Tepals much shorter, rhombeo-lanceolate, toothletted 
towards the apex, one-nerved. ip cuneate-oblong, slightly 
acute or obtuse, trifid; the lateral lacinie rhomboid or semi- 
ovate. The lamelle in the disk are sometimes short, sometimes 
so long as to reach nearly to the apex of the lip, but never to the 
base; they are semiovate or semioblong, crenulated, lobed or 
entire. The trigonous column is usually keeled over its back, 
and bears a membranous border around the androclinium, either 
equally toothletted or nearly entire, or trifid with semiovate 
acute lateral parts, and an erose central part. The pollinia are 
coherent by a viscid cellular mass. @

A very free-flowering species of Pleurothallis, with thick rigid 
leaves. It seems to thrive best when grown on a small block of 
wood placed near the light, and, like most of the smaller species 
of this genus, it should not be allowed to become dry at any 
time. I received my plants from Mexico through Mons. Boucard. 
The temperature of the Mexican house suits the plant well.—
