9. L. polyphyllus, Lindl. Stem nearly simple, very stout, somewhat 

 fleshy, erect, 35 ft. high, pilose-pubescent, equably leafy up to the 

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

 6 12 in. long; leajiets 11 25, lanceolate, acute, hirsute beneath, glabrous 

 above, 36 in. long: raceme short- peduncled, dense, 1 2 ft. long: fl. 

 subverticillate, long pedicelled, % in. long 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, } in. 

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

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

 and decumbent, 23 ft. high, sparsely silky-pubescent: stipules long, 

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

 1 l**jj 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 Kange 

 valleys, and on the plains beyond.

 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

 ciliale on the margins and the midvein beneath, 1 2% in. long: racemes 

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