40 LEGUMINOS^. 



wings lightly joined, forming an obliquely obovate inflated sac ; falcate 

 keel with a long slightly ciliate beak. — Common on plains, especially in 

 sandy soil ; the most beautiful species of the group, and by no means a 

 dwarf, except in very dry seasons. 



15. L. carnosulus, Greene, Bull. Calif. Acad. ii. 144 (1886j. Erect, 

 1 — 2 ft. high, usually simple, stout and succulent ; pubescence minute, 

 appressed : leaflets oblanceolate, 1 in. long, obtuse, but with a small 

 recurved mucronation : raceme loose, distinctly verticillate : upper calyx- 

 lip deeply cleft ; lower entire : corolla deep blue ; keel villous in the 

 middle.—Near Olema, Marin Co., Greene, and perhaps frequent north- 

 ward ; for we have it from Oregon, Hovell. Readily distingiaished from 

 the last by its succulent herbage. 



16. L. atlinis, Agardh, Syn. 20 (1835). Very stout and succulent, 

 irregularly branching above (not from the base), 1 — 2 ft. high, Tisually 

 almost glabrous, the pubescence very sparse and short ; stipules small, 

 setaceous : leaflets 7, cuneate-obovate, obtuse or emarginate, 1 — l^o in- 

 long, on stout petioles twice or thrice as long : racemes rather short- 

 peduncled ; whorls 3 — 7 ; bracts equalling the calyx ; upper calyx-lip 

 bifid ; lower entire or 3-toothed : corolla 5 —6 lines long, deep bluish 

 purple ; keel broad, not strongly falcate, naked : ovary densely velvety ; 

 pod glabrate, 1 — 2 in. long, 5— 9-seeded.- -Common in low, clayey soils, 

 mostly near the sea ; but also in the interior, where it is more pubescent. 

 Although authors who have seen the types say that this plant is the real 

 L. affinis, Agardh's description does not well apply to it. Doubtless 

 No. 15, which no field botanist could confuse with the present species, 

 has been mixed with it by various authors ; possibly by Agardh himself. 



17. L. cervinus, KeUogg, Proc. Calif. Acad. ii. 229, fig. 72 (1868). 

 Stout, pale green, appressed-pubescent, 1 ft. high : stipules STibulate, 

 short ; leaflets 7, cuneate-obovate, obtuse, mucronulate, 1 — 2 in. long : 

 raceme greatly elongated ; whorls distinct, many-flowered ; flowers on 

 very short pedicels : upper calyx-lip cleft ; lower 3-toothed, the middle 

 tooth slightly longer : corolla pale blue ; banner orbicular, pubescent 

 exteriorly ; keel ciliate along the margin, and pubescent on the lower 

 edge : ovary villous, 7-ovuled. — Pine woods of the Santa Lucia Mts., 

 Lohh. Evidently a good species, but perhaps not of this group ; very 

 possibly perennial.

18. L. polypliyllus, Lindl. Bot. Reg. t. 1096 (1827). Stem solitary, 

 nearly simple, very stout, somewhat fleshy, erect, 3—5 ft. high, pilose- 

 pubescent, equably leafy up to the inflorescence : stipules adnate for half 

 their length or more ; petioles 6-12 in. long ; leaflets 11—15, lanceolate,
