long) corolla; pod narrowly linear, glabrous, about 1 in. long, -5 to 

 7-seeded; seeds oblong, smooth, dark colored. — (Hosackia Purshiana 

 Benth.) 



Banks of streams, dry hillsides, or on the level lands of the valleys 

 and plains; very common and widely distributed, conspicuous in the 

 late summer and fall months. 



11. L. humistratgs Greene. Herbage soft-villous, branches from 

 the base decumbent, or ascending, or more often prostrate and 

 forming mats 5 to 9 in. broad; leaflets 4, narrowly oblong or cuneate- 

 obovate, 3 to 5 lines long, the rachis over J line broad; flowers 

 sessile, or nearly so, yellow, 3 or 4 lines long; calyx-teeth linear, 

 much longer than the tube; wings at base of blade joined above ovary 

 as in the next; pod oblong, pilose, 4 lines long, 2 or 3-seeded.^ 

 (Hosackia brachycarpa Benth.) 



Abrupt sunny hillsides in clayey soil; Coast Ranges and Sierras. 

 Less common than the next. 



12. L. subpinnatus Lag. var. Wrangelianus. Annual, low, 

 diflFusely branched, 4 to 7 in. high; herbage sparsely pubescent with 

 short hairs, canescently villous, or nearly glabrous, especially on the 

 upper surface of the leaflets; foliage similar to the preceding; flowers 

 distinctly pediceled, bright yellow, 4 to 4 J lines long; calyx-teeth 

 broadly subulate, as long as the tube; wings joined on the upper side 

 of the ovary by the lobes or processes at the base of the blade, their 

 tips meeting above the keel, but not enfolding it; pod pubescent, 

 linear, 7 to 9 lines long, 5 to 7-seeded. — (L. Wrangelianus V. & M.) 



Common in the hill country from the outer (or seaward) to the 

 inner Coast Ranges. Apr.-May. Probably ours is not even 

 varietally distinct from the type, which is Chilian and exhibits 

 variations similar to the plant of California. 



13. L. Heermanni (Dur. & Hilg.) Greene. Very near the next, 

 less pubescent, the pubescence whitish, the herbage of a light green; 

 stems prostrate, several from the root, 2 to 3 ft. long, with long 

 branches throughout their length; leaflets somewhat broader and more 

 acute; flowers one-half as large; calyx hirsute with whitish hairs; 

 corolla yellow turning to deep red. -^(Hosackia Heermanni Dur. & 

 Hilg.)
