succulent. "Stem ‘erect, fistular, leafy. Leaves between succulent and coriaceous, glaucous, finely 
striated, with parallel veins, 5 — 6 inches long and about an inch and a half broad, oblonglanceolate, 
their margins running' down and meeting at a litle more than an inch below the point, where the 
middle part of the leaf separates from the stem. Flowers about three inches long, rose coloured, 
solitary in the axils of the three-four upper leaves. Sepals patent, linear-lanceolate, acute. Petals 
conniving, lanceolate, with a- prominent midrib on their internal surface, rose coloured, but towards 
the tips sanguineous. Labellum free, convolute, oblonglinear, truncate, emarginate. Crest spongy, 
yellowish towards the base, becoming more fleshy and considerably elevated above the disk. At each 
— side of its base, but seated on the disk, there is a small roundish yellow gland. Like the other segments 
of the perianth the labellum is rose coloured except its upper third, which is of the same teler, 
as the tips of the petals. Column clavate, semiterete, white, the upper part of its internal face 
of a papillose nature and yellowish. Stigma infundibuliform, its lateral margins toothed. —Anther 
large, fleshy, terminal, operculiform, subbilobed, purple, suspended by a lobed po of the upper 
part of the back of the column. Germen sessile, fleshy, eylindrical, about 2” long. — - Nearly allied 
to C. rosea Lindl., but is well distinguished by its truncate and emarginate, not acute labellum, and 
by the crest being entire at and below the middle. Marshy places in upland campos near Natividade 
and Arrays, province af Goyaz, Brazil. Flowering from January-March. Gardner! Serra dos Orgaos.
