Root small, composed of a few simple fibres. Plant gutted, about 6 inches 
in height. Stem rounded, erect, monophyllous, furnished with brown 
and dry sheaths, of which the upper one is carinated, and the longest. 
Leaves oblongo-lanceolate, nearly flat, almost nerveless, emarginate, fang 
_ er than the stem. 
Raceme four times longer than the leaf, slender, with the peduncle inter- 
ruptedly sheathed, equal in length with the leaf, furnished at.the base 
with the rudiment of a leaf. Flowers pale green, rather large, variously 
turned, but generally with the lip forward. Pedicels slender, articulate 
with the germen, furnished with a cylindrical, subtruncated, closely 
folded bractea. Perianth of 4 leaflets, patent, the leaflets quite glabrous, 
ovato-lanceolate, the lower one 2-nerved. Lip anterior, thrice as small 
as the perianth, with the claw winged, appressed to the base of the co- 
lumn, and slightly articulated with it; border oblong, plane, and as it 
were hastate, obsoletely 3-nerved. Column standing forward, shorter 
than the lip, attenuated upwards, on each side incrassated at the mar- 
gins, which are confluent at the base. Stigma small, quadrate, concave. 
Rostellum (a process above the stigma) protruded. Receptacle of the An- 
ther (Clinandrium, Lindl.) subcucullate, winged. Anther globose, oper- 
cular, terminal, deciduous, inserted within the margin of its receptacle, 
internally 1-celled. Pollen-masses 2, roundish-ovate, cereaceous, having 
at the extremity a common, short, pulverulent point of attachment.—.
