Flowers dark purple; the helmet gives the plant the appearance of a 
snail, Gunn. Very near C. fimbriata, from which it seems to differ in 
having much larger flowers ; perhaps it is only a southern variety.

Perianthium ringens. Sepalum supremum oblongum, fornicatum ; late- 
ralia cum petalis angustissima, subulata. Labellum petaloideum, n 
basi columnam amplectens, bisaccatum ; limbo patente subbilobo intus 
bicalloso. Columna nana, carnosa, stigmate totam faciem occupante.
