An annual or biennial, somewhat hirsute, simple or little branched herb, with long-peti- 

 oled ovate cordate crenate leaves, and large white flowers in a terminal leafy-bracted spike. 

 Calyx campanulate-oblong, membranous, deeply 4-cleft, inflated in fruit, faintly aud irregu- 

 larly veined, the lobes narrowly lanceolate, the two upper shorter than the lower. Corolla 

 much longer than the calyx, its tube narrow below, much expanded above, 2-lipped; upper 

 lip concave, entire; lower lip spreading, -3-lobed. Stamens 4, didynamous, ascending under 

 the upper lip of the corolla; filaments villous; anthers glabrous, 2-celled, the sacs divaricate, 

 the contiguous ones of the upper pair of stamens sterile and connate. Ovary deeply 4-lobed; 

 style unequally 2-cleft at the summit. Nutlets ovoid, smooth, sharply angled. [Greek, 

 stamens-together.] 



A monotypic genus of southeastern North America.

 basal ones broadly ovate, or nearly orbicular, pal-

 monly shorter than the petiole; floral leaves ses- 

 sile, ovate or ovate-lanceolate, acute or acuminate, 

 the flowers solitary in their axils, the uppermost 

 leaves very small; calyx hirsute, its lobes about as 

 long as the tube; corolla i'-i)^' long, showy, the 

 lower lip with purple lines.

 sometimes keeled, entire or emarginate; lower lip spreading, 3-cleft. Stamens 4, didyna- 

 mous, ascending under the upper lip of the corolla, the anterior pair the longer and their 

 filaments with hooked appendages at the base; anther-sacs divergent. Ovary deeply 

 4-lobed; style subulate, 2-cleft at the summit, one of the lobes smaller than the other. 

 Nutlets ovoid, glabrous, or pubescent above. [Greek, mullen, in allusion to the thick 

 woolly leaves of some species.]
