16 LEGUMINOS.E. 



5. P. GLANDULOSA, Linn. Sp. PI. ed. 2. 1075 (1762). Shrubby or arbo- 

 rescent, with loose elong'ated branches ; glabrous, but roughish with 

 elevated glands : leaflets ovate-lanceolate, acuminate, 2 or 3 in. long ; 

 stipules subulate-setaceous, deciduous : racemes longer than the leaves, 

 the bluish flowers more or less verticillate. — Native of Chile ; frequent in 

 cultivation, occasionally spontaneous. 



6. P. Califoriiica, Wats, in Gray, Proc. Am. Acad. xii. 251 (1877). Low, 

 tufted ; pubescence short, silky, appressed : leaves palmately 5-foliolate ; 

 stipules scarious, lanceolate, deciduous ; leaflets broadly oblanceolate, 

 acutish, ''}^ — 114: in- long : racemes shorter than the leaves, short- 

 peduncled, rather loose ; pedicels slender : calyx silky-villous, % in. 

 long, the linear acuminate lobes a little exceeding the petals : pod thin, 

 villoixs, oblong with a lanceolate beak : seed compressed, 2 lines long or 

 more. — Head waters of the Salinas, San Luis Obispo Co., Falmer. 



9. LOTUS, Touruefort (Lotus. Hosackia). Herbaceoxis or suffru- 

 tescent, with pinnately 3 — co - foliolate (in the first species often 1 -f oliolate) 

 leaves ; leaflets sometimes of even number but unequally distributed 

 on the two sides of the rachis ; stipules foliaceous, scarious, or more 

 commonly reduced to dark glands. Flowers solitary, or in umbels or 

 heads which are naked or subtended by a 1 — 5-foliolate bract. Calyx 

 5-toothed or -cleft. Corolla whitish, yellowish or purplish, changing to 

 orange or red ; petals free from the stamens ; banner ovate or rounded : 

 wings commonly meeting imperfectly and (by a twist in the claw) obliquely 

 m front of the obtuse or acute, sometimes rostrate keel. Stamens dia- 

 delphous ; the alternate filaments dilated or thickened under the anthers. 

 Pod linear, compressed or terete, straight or arcuate, promptly or tardily 

 dehiscent, or indehiscent, 1 — x- seeded. Seeds variously rounded or 

 elongated, sometimes quadrate, smooth, tuberculate or rugose.— A large 

 genus, related to the clovers and of some value as forage plants. The 

 American species, quite numeroiis, are mostly Californian, and have been 

 without sixfficient reason treated as constituting one or more genera 

 distinct from Lotus. 



* Annuals with gland-like traces of stipules ; leaflets 1 — 3, on a linear 

 rachis ; pods straight, readily dehiscent. — Genus Acmispon, Raf. 



1. L. Americanus, Bisch. Hort. Heidelb. (1839) ; Nutt. Gen. ii. 120 

 (1818), under Trigonella : L. sericeris, Pursh (1814), not of DC. (1813). 

 Hosackia Purshiana, Benth. Erect or decumbent, 1—2 ft. high, more or 

 less villous : leaflets (rarely 5) ovate or oblong, acutish, ^£ in. long : 

 peduncles slender, exceeding the leaves, the solitary salmon-colored or 

 whitish flower subtended by a bract 3—6 lines long : calyx-tube very 

 short, the linear teeth equalling the corolla : pod 1 m in. long : seeds 

 oblong, smooth, dark-colored. On sunny banks, or in the dry gravelly 

 beds of streams, or even in moist meadow lands ; very widely dispersed.
