Leaves radical, 8 or 9 inches long, oblong, gradually tapering from the near- 
ly cylindrical base upwards to the mouth of the tube, where it is about 
an inch and a half in its greatest diameter : it is laterally compressed, of 
a green colour, marked with longitudinal nerves and connecting reticu- 
lated veins, which, in the upper part, are of a purple colour. In the 
front of the leaf, there runs a longitudinal waved ala or mingy from the 
mouth to the base of the tube, and which is about one-third of an inch 
deep. The mouth of the tube is ovate, scarcely at all contracted, thicken- 
ed at the margin, the front declined, the back of it surmounted with a 
broadly ovato-lanceolate, acuminate, nearly erect appendage, which is 
slightly convex, the margin alone, near the base, being recurved. This 
is usually of a purphsh colour, marked with veins like the rest of the 
leaf, within covered with very minute reflexed hairs. 
Scape twice the length of the leaves, one foot and a half long, cylindrical, 
erect, green, purplish above, and curved at the extremity, bearing a 
single, drooping, large, richly coloured^wer. 
Calyx double, the outer one of 3 small, ovate, yellow-green leaflets ; the iimer 
of 5, broadly ovate, bright purplish crimson spreading leaflets, the ex- 
tremities pointing downwards, and protecting the rest of the flower. Pe- 
tals 5, broadly ovato-rotundate, remarkably contracted below the middle, 
flaccid, pendent, of a very deep, fine purple colour, greenish at their bases. 
Stamens in a hollow cup-shaped receptacle, formed by the bases of the 
petals, numerous. Filaments rather short, purplish dotted. Anther insert- 
ed by the middle of its back, nearly horizontal, oblong, yellowish, form- 
ed of 2 cells, which open with a large aperture at the extremity. Pollen
