Stem, in our plants about four feet in height, slender, weak, flexuGse, sulFru- 
ticose, rough with minute pubescence, cylindrical, green, slightly branch- 
ed. Leaves distant, scattered, broadly lanceolate, attenuated at the base, 
denticulato-serrate at the margin, acute, nerved, glabrous above, minute- 
ly pubescent beneath. 
Flowers in terminal racemes, at first drooping. Peduncle very short, with a 
small, narrow, foliaceous bractea at the base. Calyx superior, tubular at 
the base ; the limb of four linear segments, but adhering for the greater part 
of their length, opening only on one side entirely, to admit the expansion 
of the corolla, and standing out nearly horizontally. Petals four, placed 
, upon the summit of the tube of the calyx, very large, obversely cordate, 
spreading, waved, pure white, yellow at the base, and sending upwards 
several yellowish-green, slightly diverging nerves, becoming rose-colored 
previous to decay. Stamens eight, inserted just within the tube of the 
calyx. Filathents nearly equal in length to the corolla, erect, alternately 
shorter. Stamens long, linear, placed transversely, with their centre on 
the top of the filament. Pollen yellow, cohering together, and hanging 
attached to the stamens stigmas and style, in great abundance, after the 
bursting of the cells. Germen inferior, subclavate, but slightly attenuated 
at both ends and quadrangular, pubescent. Style filiform, longer than 
the stamens. Stigmas four, spreading cross-wise, linear, afterwards pen- 
dent.
