 " blue " ? ) : wings lanceolate or obovate : leaves without conspicuous glands. 



P. puberula, Gkav. Puberuleut, branched from the base: lowest leaves sometimes oval 

 or often like tlie others linear, lance-linear, or linear-oblong : wings obovate, obtuse, siiorter 

 than the keel : ca])sule suborbicular, emarginate, 4 lines in diameter, glabrous or puberulous 

 upon the surfaces, pubescent upon the very narrow margin ; seeds obovate-oblanceolate in

P. ovatifolia, Gray. Moderately branched from a lignescent base, soft tomentose-pubes- 

 cent : leaves ovate, obtuse or acutish, shortly petiolate, pubescent upon both surfaces, 8 to 

 10 lines long, two thirds as broad ; the uppermost somewhat narrower, ovate-lanceolate : 

 wings lanceolate, acute or acutish, shorter than the keel : capsule large (at maturity 5 lines 

 iu diameter), orbicular, smooth on the surfaces but strongly ciliated upon the rather broad 

 and distinctly marked border ; seeds ovate, finely silky-villous and with hood-shaped puber-

ace. to Chodat; P. ovalifolia, DC. Prodr. i. 331), of Mexico differs in its shorter puberuleut 



rather than pubescent indumentum, obtuser leaves, and longer obtuser wings, which fully 



equal or somewhat exceed the keel. 



§ 2. Hebeclada, Chodat, 1. c. 43. Lower pair of sepals connate ; entire 

 calyx persisting in fruit : keel without crest or beak : a single species of the

S. America. 



P. grandiflora, Walt. Root lignescent : stems usually several, erect or somewhat flexu- 

 ous and spreading, slender subsimple or somewhat branched, covered with short appressed 

 puberulence : leaves ovate-lanceolate to lance-linear or narrowly linear-oldong, mostly ap- 

 pre.ssed-puberulent : racemes terminal and lateral, loose and secund ; pedicels a line or two 

 long : flowers violet-purple turning greenish in age : wings obovate-cuneate or flabelliform, 

 veiny, 3 lines long, nearly as broad : capsule elliptic-oblong, glabrous, mostly shorter than tlie 

 wings; seeds oblong, scarcely compressed, appressed-hairy. — Car. 179; Torr. & Gray, Fl.

Var. canescens, Shuttl. Stem and leaves canescent-tomentulose, the latter lance- 

 oblong, obtuse : flowers essentially as in the type. — Shuttl. in distr. pi. Rugel, no. 39, & in 

 Gray, PI. Wright, i. 41. P. grandiflora, var. puhescens, Chodat, 1. c. 57 (as to pi. descr.), is 

 probably the same, but P. puhescens rosea, Muhl., was more likely nearer the typical form. —
