344 LEGUMINOS^. Phaca. 



oblong, obtuse, slightly petiolulate ; stipules minute, triangular ; racemes ob- 

 long, spicate, many-flowered ; peduncles much longer than the leaves ; calyx 

 pubescent with blackish hairs, with very short subulate teeth, at length with- 

 ering ; legumes eliiptical-ovoid, obtuse at each end, not flattened, glabrous, 

 raised on a long fililbrra stipe. 



" Borders of woods near tlie sea, St. Barbara, California. April. — A robust 

 plant, about 3 feet high, nearly glabrous when old. Flowers rather small, 

 ochroleucous. Stipe almost as long as the pod. — Allied to P. alpina, but 

 with more conspicuous teeth to the calyx, a different pod, &c." Nuttall. 



7. P. canescens (Nutt. ! mss.) : "tomentose-canescent ; leaflets 10-15 

 pairs, small, oval or oblong, obtuse, scarcely petiolulate ; stipules membrana- 

 ceous, very small, triangular-subulate ; raceme many-flowered, rather loose, 

 on peduncles twice the length of the leaves ; the flowers nodding; teeth of 

 the calyx subulate, rather shorter than the tube ; vexillum elongated ; legumes 

 large, inflated, obtuse, slightly puberulent, raised on a slender stipe. 



" With the preceding, but on dry plains. — Scarcely a foot high, with small- 

 er and less crowded leaflets than P. trichopoda, which it resembles in most 

 respects: the flowers are larger, the peduncles longer, &c. The flliform 

 stipe is about twice the length of the calyx." Nuttall. 



8. P. frigida (Linn.): erect, nearly glabrous, a little branched; leaflets 

 4-5 pairs, oblong-ovate, somewhat hairy beneath and on the margins ; sti- 

 pules large, foliaceous, ovate-oblong, ciliate ; calyx pubescent on the margin; 

 legumes stipitate, oblong, inflated, membranaceous. Hook. ft. Bor.-Am. 1. p.

 14-16 pairs, oblong-oval, emarginate,villous-tomentose (as well astherachis) 

 beneath; peduncles and calyx villous; raceme compact, many-flowered;

California, Menzies, Beechey.— Flowers nodding, reddish. Peduncles 

 the length of the leaf. Leaflets obovate. DC— We have never seen this 

 species. 



10. P. neglecta: nearly glabrous; stem erect, branching; leaflets ,5-8 

 pairs, elliptical, petiolulate, minutely puberulent with appressed hairs beneath ; 

 stipules triangular-ovate, minute ; peduncles about the length of the leaves; 

 racemes oblong, many-flowered, at length rather loose ; the flowers (white) 

 reflexed ; calvx tubular-campanulate, pubescent (as well as the pedicels) with 

 black hairs, the subulate teeth much shorter than the tube; legume sessile, 

 glabrous, coriaceo-membranaceous, globose-ovate, pointed, very turgid, flat- 

 tened on the upper side and deeply grooved by the introflexion of the placent- 

 al suture.
