leaflets, usually smooth above, and its short bracts. Dr. Kellogg's L. cervinus appears to be a 

 stout form, with large leaves and short pedicels. 



30. L. nanus, Dougl. Slender, £ to 1 foot high, often blanching from the base, 

 villous cr finely pubescent: leaflets linear to oblauceolate, half to an inch long, 

 usually acute, pubescent on both sides, the petioles 1 to 3 times longer : racemes 

 loose ; bracts exceeding the calyx ; pedicels slender : upper calyx-lip 2-cleft : petals 

 usually 5 or 6 lines long, very broad, bluish-purple or at hrst nearly white ; the 

 standard shorter and usually marked with dark-purple lines : ovules U to S : pod i 

 to 1} inches long. — Benth. in Hort. Trans, n. ser. i. 409, t. 14 ; Watson, 1. c. 



From Sacramento Valley to Southern California, frequent. Flowering in early spring and 

 rather variable. 



31. L. micranthus, Tloiigl. .Slender, 3 to 12 inches high, villous: leaflets 

 linear, ^ to 1 inch long : racemes short, often rather dense ; bracts shorter than tin- 

 calyx ; pedicels a line long or less : calyx-lips broad, the upper with short triangu- 

 lar lobes : petals 2 or 3 lines long ; the wings and standard very narrow. — Lindl. 

 Bot. Beg. t. 1251 ; Watson, 1. c. 



Var. microphyllus, Watson, 1. c. The lower and more hirsute form, with the 

 leaflets but 3 to (j lines long. 



Var. bicolor, Watson, 1. c. Flowers a little larger, with the petals somewhat 

 broader, and pedicels 1 or 2 lines long. — L. bicolor, Lindl. Bot. Beg. t. 110U. 



Var. trifidus, Watson, 1. c. Very hairy; lower lip of the calyx 3-parted. 



From Paget Sound to Southern California, very frequent ; the var. trifidus near San Francisco, 

 remarkable for the division of the calyx. The var. bicolor approaches forms of L. nanus, and 

 tends to unite the two species. 



■*- 4- Flowers scattered: bracts more or less persistent, except in L. lejitophyllus and 

 L. Sliveri : ovules 4 to 6, or 8 in L. truncatus. 



32. L. leptophyUus, Benth. Slender, rarely branched, 1 or 2 feet high, vil- 

 lous : stipules linear-setaceous: leaflets 8 to 10, narrowly linear. 1 to 1.', inches 

 long, glabrous above; the very slender petioles 2 or 3 times longer: racemes" 3 to 10 

 inches long; bracts setaceous, much exceeding the calyx: upper calyx -lip narrow, 

 deeply cleft: petals 5 or 6 lines long, bluish-lilac, with a deep-crimson spot upon 

 the standard. — Hort. Trans, n. ser. i. 40'J ; Watson, 1. e. 536. 



Sacramento Valley and southward, on hills and in rocky places. A form occurs with rather 

 broader leaves. 



33. L. sparsiflorus, Benth. Very slender, sparingly branched, 1 to U feel 



high, villous with spreading hairs : upper leaves much reduced : leaflets 5 I" 9, 

 linear, \ to 1 inch long; the narrow petioles 2 to I lines longer: bracts linear 



setaceous, shnrter Mi. ill the calyx, subpersistent ; pedicels diorl : upper Calyx-lip 

 2-parted : petals violet, 5 lines long; the standard shorter: pod a half to an inch 

 long. — PL Hartweg. 303; Watson, 1. c. 

 From the Sacramento Valley to Southern California. 



34. L. truncatus, Xutt. Rather stout, sparingly branched, 1 to 2 feel high; 

 finely pubescent, becoming nearly glabrous: stipules short, subulate; leaflets 5 to 7. 

 linear, narrowed from the truncate or somewhat 3-toothed apex to the base, smooth 

 above, : , ! to 1 1 inches lung, nearly equalling the peti,.|e : bracts short, subpersistent : 

 pedicels \ in 2 lines long: upper calyx-lip 2-clefl : pel I deep-purple, I or 5 lines 

 long ; the standard shorter : pod 1 ', inches long. — Hook. & Am. Bot. Beechey, 336;
