1921] Smiley: Flora of the Sierra Nevada of California 253 



Jeffrey Pine belt, Purpus 1794; near Mineral King, V. Bailey (Death 

 Valley 1550, 1654) ; rocky slopes on Old Mt. Whitney, 12-13,000 feet, 

 Purpus 1676 ; North Fork of Kern River, 12,000 feet, Rothrock 391 ; 

 Kaweah meadows, dry woods, 10-11,000 feet, Purpus 5340; Mt. 

 Olancha in Pinus Balfouriana belt, 10,500 feet, Hall and Babcock 

 5247 ; Mt. Pinos, Rothrock 270. 



Although all of the collections above cited do not agree in detail 

 and some of the forms from the highest altitudes present an aspect 

 quite different from the lower mountain and typical form, yet exam- 

 ination failed to disclose characters which would appear to justify 

 taxonomic differentiation.

 L. Lyallii var. Danaus Wats., Proc. Am. Acad., vol. 8, p. 534. 1873. 



Type locality. " Mount Dana, alt. about 12,500 feet, Bolander," 



Range. Central Sierra (Mt. Dana) to the Mt. Whitney region. 



Zone. Arctic-alpine. 



Specimens examined. Mt. Dana, 12,000 feet, Congdon, August 

 11, 1898; same locality, Bolander 5087 (type); foot of Mt. Dana, 

 10,000 feet, Congdon, August 10, 1898 ; Mt. Dana, 11,400 feet, Smiley 

 722; between Mts. Dana and Gibbs, 10,400 feet, Hall and Babcock 

 3623 ; Mt. Gibbs to Walker Lake, Congdon, August 16-17, 1894 ; Silver 

 Mountain, Hooker and Gray in 1877 ; Mt. Lyell, 9,500 feet, Hall and 

 Babcock 3556; Mt. Whitney, flats near Langley's Camp, Hall and 

 Babcock 5542. 



Perhaps the range of this species extends further north than 

 usually believed; Dr. Merriam reports 53 that a plant collected along 

 timber line on Mt. Shasta has been determined by Leiberg as belong- 

 ing to L. danaus, but I suspect that the identification should be with 

 L. Lyallii Gray (I.e., p. 334), an arctic-alpine of the Cascades of Wash- 

 ington and Oregon, distinguished by peduncles more hairy and the 

 larger flowers purple, not nearly white as in our species. 



6. Lupinus longipes Greene, Fl. Fran., p. 41. 1891. 



L. procerus Greene, Muhl., vol. 6, p. 10. 1910. 



Type locality. "Along streams at middle or higher elevations in 

 the Sierra, northward to Oregon." 



Range. Southern Oregon southward through the Sierra to the 

 San Bernardino Mountains of southern California. 

 - Zone.- Transition and Canadian, rarely higher.
