Root perennial, composed of thick fleshy fibres. Stem eight to ten inches

nerved, somewhat pubescent underneath, sessile, sheathing at base. Flow- 
ers generally solitary. Exterior segments of the perianth three, ovate lan- 
ceolate, expanding, two interior narrower, longer, tortuous, bearded on the 
inner surface near the base, all of an obscure green colour with brown lines 
externally pubescent. Lobe of the style triangular, somewhat sagittate. 
Labellum yellow, with obscure spots, shorter than the petals, smooth on the 
outsides, bearded within at base.

Petals green, dotted with red. Labellum yellow, contracted at the 
mouth. From the preceding which it resembles very much, it differs by a 
flower twice as large and by the different figure of the lobe. Stem one to 
two flowered. All of the American species have their leaves pubescent, 
but the hairs in this are more evident. Willd. 
The leaves, too, in my specimens are larger, more distinctly nerved, and 
the narrow segments of the perianth longer; but the plant not as pubescent 
as C. Spectabile.
