both extremities; all are opposite, sessile, quite entire, and strongly 
marked with three parallel nerves. Corymb terminal, bearing 
several large, handsome, richly coloured flowers, on moderately 
long slender peduncles. _ Calyz large, somewhat inflated, deeply 
cut into five lanceolato-subulate segments ; a wing appears down 
the middle of each segment, which, from being broad on the tube, 
gradually loses itself on the lobe. Corolla rotate, of five large, 
broad, ovate, spreading, deep purple segments, rather oblique. 
Stamens five. Filaments short; anther large, yellow, linear-su- 
bulate, approximating into a cone, each opening by two pores at 
the extremity. Ovary oval, glabrous. Style filiform, declined.
