LiUpinus purpurascens 



Perennial, stout, about 7 dm. high, the stems herbaceous, 

 leafy and with some short sterile secondary branches not exceed- 

 ing the leaves, whitened with short, mostly appressed hairs: 

 stipules setaceous, 5 mm. long: petioles rather stouj:, 5 cm. long, 

 pubescent like the stems; leaflets, thick, commonly 7, oblanceo- 

 late, 6 cm. long or less, 1.5-2 cm. wide, the apex acute or acut- 

 ish, the upper side light green, sparsely and shortly appressed 

 pubescent, the under side more densely so, whitened: peduncle 

 short, about 4 cm. long: inflorescence 2 dm. long, dense: flowers 

 violet, large, whorled, 1.5 cm. long, i cm. across: pedicels stout, 

 7 mm. long, densely short hairy, as is the calyx, the lobes of 

 which are entire, the lower one i cm. long, the upper 8 mm.; 

 banner with the edges turned back and parallel, the apex end- 

 ing in a short cusp, the face darker than the other parts, of a 

 deep rich purple; wings obliquely obovate, exposing the keel; 

 this strongly curved, pale, densely bearded on the lower half,

The type is no. 7847, collected May 25, 1905, on banks 

 near the railroad just above Redding, Shasta county, California. 

 It occurs at intervals along the upper Sacramento, perhaps as 

 far north as Castella. It is a relative of L. albicaiUis. 



LuPiNUS ALBICAUUS Dougl.; Hook. Fl. Bor. Am. 1: 165. 1833. 

 No. 8 10 1, collected July 14, near Nevada City, Nevada 

 county, along the electric railroad in a field. This is apparently 

 the plant which passes in California under the above name, but 

 the writer did not see it in the northern part of the State, where 

 it should be found. Watson, in the Botany of California ,came 

 nearer to an accurate description of the flower than any other 

 writer when he says: "the standard naked, acute with the mar- 

 gins coherent near the apex." In our specimens they are more 

 nearly coherent at the base, above that parallel, the pointed 

 apex curved back. When fresh the flowers are pale violet-pur- 

 ple with a darker spot on the face of the banner, but turn tawny 

 in drving-.
