Descr. Root a large, somewhat globose, depressed 
tuber. Stem erect, four to five feet high, rounded, purple, 
hairy, below marked with darker streaks; branches oppo- 
site, short, not bearing flowers. Leaves opposite, ovato- 
oblong, obtuse, wrinkled, crenate, downy and somewhat 
scabrous : petiole varying in length in the lower part of the 
plant, nearly half as long as the leaf, channelled above. 
The upper part of the stem becomes suddenly bare of 
leaves, and bears numerous pseudo-verticils of flowers, 
thus constituting a raceme, one or two feet in length. 
Peduncles, generally in threes, from three lines to an inch 
in length. Calyx inflated, five-angled, deeply cut into 
five, acute, triangular segments, scabrous. Corolla bright 
scarlet: tube slightly curved and a little inflated near the 
middle, remarkably dilated and inflated at the base. The 
limb oblique, five-lobed, within spotted with yellow, upper 
lobe much broader than the rest, emarginate. Stamens 
four: Anthers meeting in a cross-shaped manner. Germen 
oblong, with five yellow glands, of which two larger ones 
are combined. Style rather longer than the flower.
