Root composed of many large, much branched, yellowish, anastomosing 
and fleshy fibres, similar to that of our European C. innata. Stem about 
a foot high, of a reddish-purple colour, terete, jointed, leafless : in Keu 
of leaves it is furnished with large, cylindrical, somewhat inflated, 
sheathing, pale brownish scales, which, at the top, are cut down a little 
way on one side. 
Flowers arranged in a rather loose terminal spike, about 20, erect, each 
subtended by a small scale or bractea, which is bifid or trifid at the 
point. The three outer segments of the perianth are moderately spread- 
ing, linear-lanceolate, dingy yellow, brown at the lips, united together 
below,' the two lateral lower ones of these unite at the base in front, and 
form a yellow sac or short spur, the back of which is adnate with the top 
of the germen : Two inner segments lanceolate-obtuse, yellowish-brown, 
spmewhat connivent over the column. Lip about equal in length with 
the other segments of the perianth, pure white, of a nearly oval form, 
reflexed at the extremity, 3-lobed ; the two lateral lobes or teeth small, 
and sometimes denticulate, the intermediate one large, with two ele- 
vated longitudinal ridges near the base, the margin crisped, and extre- 
mity notched ; the whole is more or less sprinkled with purple dots, 
especially at the base. 
Column of fruclifcaiion semicylindrical, slightly curved forward, terminated 
by the hemispherical, deciduous, operculiform anther. This Anther in- 
closes 4 ovate, deep yellow pollen-masses, which are united by their 
base to a pellucid oblong gland. Stigma subquadrate. Germen clavate^ 
reddish-purple, erect, twisted at the base.
