 flowered : pedicels very short, spreading : calyx-teeth slender-subulate, a little 

 shorter than the campanulate tube: corolla "yellow" (apparently cream-color), 

 narrow, half an inch long : pod half an inch or so in length, 2 lines wide, dorsally 

 convex and ventrally almost straight, nearly erect upon an ascending pedicel ; the

 section broadly obcordately '2-lobed, coriaceous, glabrous: leajiets 1 to 12 pairs. 



33. A. arrectUS, Gray. A foot or more high, minutely pubescent or glabrate : 

 stipules distinct : leaflets from linear to oblong, retuse (a third to two thirds of an

 Exp. 69.

 very near the borders of California, but to be expected. Flowers two thirds of an uich long. Pod 

 from that to an inch in length. 



34. A. Bolanderi, Gray. A span or two high : stipules scarious and united 

 on the side of the stem opposite the petiole : leaflets oblong-linear or narrowly ob- 

 long, grayish with soft pubescence (a third to half an inch long) : peduncles not 

 exceeding the leaf, almost capitately 6- 12-flowered : calyx-teetli slender-subulate, 

 a little shorter than the tube : corolla white with a tinge of purple : pod ovate, in- 

 curved, transversely veiny, less than an inch long, abruptly recurved or reflexed on 

 the conspicuous ascending stipe. — Proc. Am. Acad. vii. 337.

 &c.), to Sierra Co., Lemmoii. Flowers half an inch long. 



* * Pod sessile in the ccdyx {or sometimes on a shor't included stipe) and in size much 

 exceeding it, except in the last species. 



-i- Stems elongated, at least a sjmn or tivo in length. 



-^-}- Flowers about an inch long, few and loose. 



35. A. nudus, Watson. A foot or two high, cinereous with minute appressed 

 pubescence or glabrate : stems branching and flexuous, slender : petioles and angled 

 or flattish rhachis rigid, elongated, bearing a few scattered linear leaflets (varying 

 from 4 to 8 lines long) : peduncles elongated, 5 - 8-flowered : calyx cylindracoous,
