4 LEGUMINOS^. 



be referred to T'. Americana, on account of its low zigzag stems, short 

 and simple tendrils, subcoriaceous leaflets, and soft-pubescent herbage. 

 It may be the T'. iruncata, var. villosa, Kell. 



* * Few-flowered annuals. 



5. T. exig-ua, Nutt. in T. & G. Fl. i. 272 (18.38). Slender, 1-2 ft. high : 

 leaflets 4 or 6, oblong-linear, obtuse : peduncles filiform, shorter than 

 the leaves, 1 — 2-flowered : calyx-teeth lanceolate from a broad base : 

 corolla white or purplish, 2 lines long : pod glabrous, 4 — 5-seeded. — Hill- 

 sides or plains, preferring stony or sandy soil. Mar. — May. 



6. V. Hassei, Wats. Proc. Am. Acad. xxv. 129 (1890). Taller and less 

 delicate than the last, the leaflets ampler, more numerous, deeply notched 

 at apex : fl. 3 lines long : pod shortly stipitate, 5— Bseeded. — Of more 

 southerly distribution than the preceding, but found at Benicia, Bigelow, 

 and Santa Cruz, Anderson. 



7. V. SATiVA, Linn. Sp. PI. 736 (1753). Stoutish, suberect, 2--3 ft. 

 high : leaflets 8 or 10, obovate-oblong, truncate or refuse, mucronate : fl. 

 1 or 2, subsessile, % in. long, red-purple. — The Vetch or Tare, cultivated 

 from time immemorial as a food and fodder plant, must have been brought 

 to California a century ago by the Missionaries, and is of frequent occur- 

 rence by way-sides and in old fields in most parts of the State. 



3. LA.THYRUS, Theophrastus (Wild Pea). Coarser plants than 

 Vicia, with broader leaves and flowers, the style villous in a line up and 

 down the inside (next the free stamen). 



* Tendril-bearing; the racemes 7nany-flowered. 



1. L. polyphyllus, Nutt. in T. & G. Fl. i. 274 (1838). Glabrous, stout- 

 ish, the stem angular, 2 — 3 ft. high : leaflets 5 — 10 pairs, oblong, obtuse, 

 distinctly petiolulate : tendrils short : stipules as large as the leaflets, 

 triangiilar, acute, with or without sharp triangular teeth at base : pedun- 

 cles shorter than the leaves : calyx-teeth subulate, ciliate, the lower twice 

 as long as the upper : corolla % in. long, purple. — This, common in 

 Oregon, is attributed to Humboldt Co., Bolander, but is otherwise 

 Tinknown within the State ; but the next is very closely related to it. 



2. L. Bolauderi, Wats. Proc. Am. Acad. xx. 363 (1885). Often shrubby 

 below, 3 — 5 ft. high : leaflets 3 — 5 pairs, ovate, obtuse or refuse, mucro- 

 nate, 1 — 11^ in. long, thin, on very short petiolules : tendrils ample : 

 stipules broadly semisagittate, acute, more or less toothed : peduncles 

 equalling the leaves : lower calyx-teeth lanceolate-acuminate, longer 

 than the tube ; upper very short, broadly triangular, all glabrous along 

 the margin, or nearly so : corolla ,^4 in. long, rose-purple, fading yellow- 

 ish. — Frequent on wooded slopes throughout the Bay region and north- 

 ward to Oregon. June.
