Annual, 2-12 dm. tall from a taproot, hispidulous or scabrous throughout, the leaves ap- 

 pressed-hirsute, the inflorescence densely short-pubescent and hispid ; stems ascending, prostrate, 

 or erect, branching or simple. Basal leaves oblong-oval to broadly ovate, 4-12 cm. long, 2.5-9 cm. 

 broad, 1-2-pinnate, the oblong or lanceolate divisions toothed, incised, or pinnatifid, the petiole 

 usually much shorter than the blade ; cauline leaves like the basal, but short-petiolate or sessile ; 

 flowers numerous, short-pedicellate, in scattered, simple or few-branched cymes, the cymes 

 2-12 cm. long, erect in fruit; calyx-lobes narrowly lanceolate or oblanceolate to obovate, fre- 

 quently unequal, 4-6 mm. long, 0.5-3 mm. broad, densely pubescent and hispid, a little enlarged 

 in fruit ; corolla cream, bluish white, or purplish blue, broadly campanulate, deciduous, 6-12 mm. 

 long and broad, the lobes obovate, 3-5 mm. long, the whole exceeding the calyx ; stamens a little 

 longer than the corolla or sometimes included, 8-13 mm. long, the filaments glabrous, the anthers 

 oblong-oval, about 0.8 mm. long; scales semi-ovate, free at apex; style a little longer than the 

 corolla, 7-12 mm. long, glabrous, cleft three-fourths; capsule globose, 2-3 mm. long, hispid; 

 seeds 2-4, oblong-oval, 2-3 mm. long, brown, coarsely foveolate.

 crenate divisions or leaflets, at least the lower petiolulate; cymes dense but slender and elongate; calyx-lobes linear, 

 hispid, unequal; corolla pale bluish lilac or violet to white, tubular-campanulate, 3-6 mm. long, not exceeding the

 ous, 4-5 mm. long and broad, the lobes oval, 1.5-2 mm. long, the whole a little longer than the
