LEGUMINOSE. (PEA FAMILY.) 41 
7. albicaulis, Dougl. Distinguished by its flowers; which are light-blue to white, 
the standard strongly reflexed, the margins cohering near the apex, naked, acute; the 
narrow keel very strongly falcate. 
8. L. affinis, Agardh. Stem a foot high; leaflets broadly wedge-obovate, emargin- 
ate or obtuse, an inch long or more; the petioles twice longer; petals 5 lines long; the 
keel usually naked; bracts short. 
9, L. nanus, Dougl. Slender stem 6 inches to a foot high, villous, often branching 
from the base; leaflets linear to oblanceolate, half to an inch long, the petioles 1 to 3 
times longer; bracts exceeding the calyx; petals very broad, 5 to 6 lines long, bluish- 
purple, or at first nearly white; the standard shorter and usually marked with purple 
lines. 
10. L. micranthus, Dougl. Similar to the last, but the flowers smaller, in usually 
shorter more dense racemes; bracts shorter than the calyx; petals 2 to 3 lines long, 
narrow. 
Var. microphyllus, Wat. The lower and more hirsute form, with leaflets but 3 to 
6 lines long. 
Var. bicolor, Wat. Flowers larger, more like L. Nanus. 
Var. trifidus, Wat. Very hairy; lower lip of the calyx 3-parted. 
1l. L. leptophyllus, Benth. Rarely branched, 1 or 2 ft. high, villous; leaflets 
narrowly linear on slender petioles; smooth above; bracts setaceous, much exceeding the 
calyx; petals 5 or 6 lines long, bluish-lilac, with a deep crimson spot upon the standard. 
12. I. sparsiflorus, Benth. Very slender, sparingly branched, 1 to 14 ft. high, vil- 
lous, with spreading hairs; upper leaves very small; leaflets 5 to 9, linear, } to 1 inch 
long; petals violet, 5 lines long, the standard shorter; pod half an inch long. 
13. L. truncatus, Nutt. Stout, branched, 1 to 2ft. high; leaflets linear, narrowed 
from the truncate or somewhat 3-toothed apex to the base, smooth above, 2 to 14 inches 
long, nearly equaling the petiole; petals deep-purple, 4 or 5 lines long, the standard 
shorter; pod about an inch long. 
Here belongs L, Stivent, Kellogg. A beautiful species of the Sierra Nevada, with yellow standard 
and rose-colored wings. 
14, L. hirsutissimus, Benth. A foot high or more, very hispid, with spreading 
straight and viscid stinging hairs; leaflets broadly cuneate-obovate, obtuse or retuse, 
rarely acute, mucronulate; flowers in loose racemes, reddish-purple, large. 
15. L. microcarpus, Sims. Villous, with long hairs, 6 to 18 inches high; leaves 
approximate on long petioles; leaflets usually 9, cuneate-oblong, obtuse or emarginate, 
smooth above, 1 to 2 inches long; calyx densely villous, large; petals purple to white, 
6 or 7 lines long; the hairy 1-2-seeded pods 8 lines long. 
16. I. densiflorus, Benth. Much resembling the last; calyx smooth or finely 
pubescent; petals yellow or ochroleucous, rarely white or pink, 
L. luteolus, Kellogg, may be found, distinguished by its more slender habit, smaller 
and fewer leaflets, and bracts exceeding the calyx.
