6 LEGUMINOS^. 



8. L. Nevadeiisis, Wats. Proc. Am. Acad. xi. 133 (1876). Erect, slender, 

 8 — 10 in. high, nearly glabrous : leaflets 2—8 pairs, ovate or oblong, 

 obtnse, 1 in. long, thin : stipules narrow, acuminate at both ends : 

 peduncles slender, at least equalling the leaves, about 2-flowered : fl. 

 nearly 1 in. long, ochroleucous : calyx-teeth triangular, short, not very 

 unequal, except the lowest one, which is lanceolate and much longer. — At 

 middle elevations of the Sierra Nevada ; also in the Trinity Mts., MarsJiaU, 

 in open woods ; strictly erect, the leaf-rachis ending in a slender recurved 

 point. 



9. L. Torreyi, Gray, Proc. Am. Acad. vii. 837 (1868) ; L. viHosvs, Torr. 

 Pac. E. Rep. xii. 58 (1860), not of Frivalds. Erect, slender, 1—2 ft. high, the 

 herbage thin, light green, fragrant : leaflets 4 — 6 pairs, with or without a 

 reduced terminal odd one, round-ovate or oblong, % in. long, mucronate : 

 stipules narrow, acuminate, the lower lobe short or almost obsolete : fl. 1 

 or 2, short-peduncled, white or pinkish : calyx-teeth narrowly subulate, 

 the upper a little shorter : pod 1 in. long, pubescent, 3 — 6-seeded. — From 

 Santa Clara Co., Charles PaJache, to Napa and northward, in dry woods. 

 Remarkable among plants of this genus as exhaling the fragrance of 

 Aspervla odorata. It forms a link between Latliyrus and the Central 

 American genus Cracca. May. 



■* * * Eachis dilated, ending in a ruditneittary odd leaflet ; peduncle 4 — S- 

 flowered. — Genus Astkophia, Nutt. 



10. L. littoralis, Endl. in Walp. Rep. i. 722 (1812) ; Nutt. in T. & G. 

 Fl. i. 278 (1838), under Astrophia ; Gray, Pac. R. Rep. xii. 58, t. 6 (1860), 

 under Orobns. Stout and low, decumbent, densely silky-villous : stipules 

 large, ovate or semihastate ; leaflets 1 — 3 pairs, cuneate-oblong, ^2 ^^• 

 long or more : peduncles exceeding the leaves ; calyx-teeth nearly 

 equal, about as long as the tube : corolla % — 94 i^^- long, banner bright 

 purple, wings and keel white : pod large, oblong, obtuse, villous, 

 8 — 5-seeded. — Strictly maritime, in sandy or clayey soil within reach of 

 the sea-spray ; Santa Cruz, Anderson, San Francisco, Andrews, Greene, and 

 far northward. The plant has as much the aspect of a Lotus as of a 

 Lathi/rns, and perhaps ought to be regarded as forming a genus ; a view 

 held by Nuttall, its discoverer. 



4. ASTRAGALUS, Dioscorides (Rattle- Weed, Loco- Weed). Herbs 

 either erect or decumbent, with unequally pinnate leaves, no tendrils, 

 persistent stipules, and axillary spikes or racemes of flowfers which are 

 usually small for the size of the plant, and rather narrow. Calyx 5-toothed. 

 Petals with slender claws, the keel obtuse. Stamens diadelphous, (9 and 

 1) ; anthers uniform. Stigma terminal, minute. Pod various, seldom or 

 never promptly dehiscent, often coriaceous and turgid, or thin and blad- 

 dery-inflated, or thin and flat ; 1-celled, or partly 2-celled by intrusion of
