•)— -t- Perennials; ft. 6 — 7 lines long.

 fleshy, erect, 3—5 ft. high, pilose-pubescent, equably leafy up to the 

 inflorescence: stipules adnate for half their length or more; petioles 

 6 — 12 in. long; leaflets 11 — 15, lanceolate, acute, hirsute beneath, glabrous 

 above, S — 6 in. long: raceme short-peduncled, dense, 1 — 2 ft. long: fl. 

 subverticillate, long pediceljed, K i n - l° n g and as broad: calyx-lips of 



, about equal length, the upper broader, both entire: wings bluish, banner 

 red-purple: keel falcate, acuminate, naked: pod 1 — 1% in. long, J£ in. 

 broad, 7— 9-seeded. — In open marshy ground from near Point Bonita 

 northward. May. 



10. L. formosus, Greene. Stoutish and suberect, or more slender 

 and decumbent, 2 — 3 ft. high, sparsely silky-pubescent: stipules long, 

 linear-setaceous, persistent: leaflets 7 — 9, linear -lanceolate, very acute, 

 ] — X% in. long, equalling the petiole: raceme subsessile, more or less 

 whorled, but rather dense: fl. 6 — 7 lines long, rich violet, the banner and 

 wings equalling, the latter entirely enfolding, the less elongated naked 

 keel. Var. Bridgesii, Greene. Stipules narrowly lanceolate, the whole 

 plant silvery-canescent, and even villous; raceme distinctly pedunculate, ► 

 the verticils more remote and distinct. — This, in various forms, is the 

 common perennial lupine of fields and orchards among the Coast Bange 

 valleys, and on the plains beyond. 



11. L. sericatus, Kell. Stoutish, decumbent, % — 1 ft. high, very 

 leafy, canesceni with a minute closely appressed silky pubescence: stipules 

 setaceously acuminate from an adnate base; leaflets 7, spatulate-oblong, 

 obtusish, 13^ — 2 in. long, on petioles as long: raceme short-peduncled: 

 fl. large, in about 5 whorls, deep purple: calyx-lips large, the upper 

 cleft, lower obscurely 3-toothed; keel slender-pointed, lightly ciliolate. — 

 An elegant species apparently confined to a limited area in the mountains 

 of Lake, Napa and Sonoma counties. 



12. L. latifolius, Agardh. Stoutish, erect, branching, 2—4 ft. high, 

 minutely appressed-pubescent, the stem not striate, dark green and 

 shining, equably leafy, the basal leaves not long-stalked: stipules linear- 

 setaceous; leaflets 5—7, broadly oblanceolate, thin, mucronulale, pilose- 

 ciliate on the margins and the midvein beneath, 1 — 2J^ in. long: racemes 

 slender-peduncled, loose, the verticils often distinct; pedicels slender: 

 calyx-teeth elongated, the upper notched slightly at the narrow apex;
