11. Lupinus calcaratus Kellogg, Proc. Calif. Acad., vol. 2, p. 195. 



1863. 



Type locality. — -None given. 



Range. — Northern and central Sierra Nevada and east on the 

 mountains of Nevada. Inner slope of the North Coast Range (Tehama 

 County). 



Zone. — Transition and Canadian. 



Specimens ex'amined. — Mt. Rose, 9-10,000 feet, Kennedy 1187; 

 Carson Spur, Alpine County, 8,500 feet, Hansen 364; trail to Castle 

 Peak, 8,400 feet. Smiley 488 ; hills around Marlette Lake, east of Lake 

 Tahoe, 8,200 feet, Hall and Chandler 4589 ; above Glen Alpine, Tahoe, 

 7,200 feet, Smiley 205 ; ridges bordering Lake Lucile, Tahoe, Dudley, 

 June 26, 1900; Glen Alpine trail to Mt. Tallac, 9,000 feet, Abrams 

 4845; Long Lake, Plumas County, 6,700 feet. Hall 9328; Little 

 Truckee River, 6,300 feet, Hall and Babcock 4532 ; near Frog Lake 

 on Mt. Stanford (Castle Peak), C. F. Sonne, July 31, 1897; Indepen- 

 dence Lake, Nevada County, 7,200 feet, Hall and Babcock 4532. 



The four collections last cited present a form with smaller flowers 

 grouped in an inflorescence less dense than usual in this species and 

 this variant has been proposed as specifically distinct — L. silvicola 

 Heller (Muhl., vol. 6, p. 81. 1910) — a conclusion which to me appears 

 unwarranted both by the vagueness of the characters assigned and 

 the inconstancy with which they appear. 



12. Lupinus laxiflorus Dougl. Bot. Reg., vol. 14, pi. 1140. 1828. 

 Type locality. — "In dry, open gravelly plains, about the great 



rapids of the River Columbia." 



Range.- — Washington to northern Sierra Nevada. 



Zone. — Transition mainh% rarely above. 



Specimens examined. — Long Lake, Plumas County, 6,700 feet. Hall 

 9328 (referred on floral and vegetative characters only, the pods im- 

 mature) ; Summit, in dry meadow, 7,000 feet. Smiley 442a. 



Both of these collections differ from good L. laxiflorus of the 

 Northwest and approach L. ccdcaratus of the Sierra: the short spur 

 of the calyx and the blue flowers in a loose elongated raceme ally 

 them with L. laxiflorus; the pointed leaflets and fine silkj^ appressed 

 pubescence are characters of L. calcaratus. 



Other lupines may reach our lower borders or locally ascend above 

 them, i.e., L. Andersoni Wats. (Ebbett's Pass, Bolander 2012) ; L. 

 Grayi Wats. (Tenaya Canon, 7,000 feet, Smiley 667), but are not to 

 be considered as components of the boreal flora of the Sierra.
