11. Baptisia elliptica Small. Foliage glabrous or minutely pubescent. Stems 3-9 

 dm. tall, sometimes zigzag, branching : leaflets 3, variable, the blades of the lower ones ob- 

 lanceolate, those of the upper leaves elliptic or sometimes broadened slightly above the 

 middle, or below it, rounded or notched at the apex, rarely acute, lustrous above, mostly 

 tapering to both ends, especially to the base, reticulated : flowers solitary in the upper 

 axils or approximate at the ends of the branches, sometimes in terminal racemes : pedicels 

 5-10 mm. long : calyx campanulate, 6-8 mm. high ; lower lobes triangular, shorter than 

 the tube : corolla yellow, about 2 cm. long ; standard with a nearly reniform blade notched 

 at the apex, truncate or cordate at the base : pods firm, the body 1.5-2 cm. long, slender- 

 beaked, strigillose, long-stipitate. 



In dry pine lands, Florida. Spring. 



12. Baptisia sphaerocarpa Nutt. Foliage glabrous or parts of it sparingly pubes- 

 cent when young. Stems 3-10 dm. tall, solitary or several together, branching : leaflets 3, 

 firm, the blades elliptic to elliptic-oblanceolate, obtuse or retuse at the apex : racemes 

 opposite the leaves, elongated, 1-4 dm. long, loosely flowered : pedicels 3-8 mm. long, sub- 

 tended by minute bracts : calyx campanulate, 6-8 mm. high ; lower lobes lanceolate- 

 acuminate : corolla deep yellow ; keel-petals 15-18 mm. long ; standard with an orbicular, 

 reniform blade fully 1 cm. broad : pods woody, the body broadly oval or subglobose, 1.5-2 

 cm. long, glabrous, stipitate, abruptly short-beaked. 



In dry soil, Arkansas and Texas. Spring and summer. 



13. Baptisia villpsa (Walt.) Ell. Foliage minutely pubescent or glabrate in age, 

 turning black in drying. Stems stout, 5-8 dm. tall, branching: leaflets 3, firm, the
