10. Lupinus shockleyi S. Wats., Amer. Acad. Arts and Sci. Proc. 22: 



470. 1887. 

 Kingman to Peach Springs, Mohave County (Lemmon in 1884, 

 Eastwood 18443), 3,300 to 5,000 feet. Western Arizona, Nevada, and 

 southeastern California. 



11. Lupinus latifolius Agardh, Syn. Gen. Lupin. 18. 1835. 

 Williams, Coconino County (Tourney 578), Prescott, Yavapai 



County (Rusby 555, Peebles et al. 2702, etc.), 5,000 to 7,000 feet, at 

 Prescott along a stream in partial shade, May to July. Central 

 Arizona and California. 



The Arizona specimens, all of which have whitish or ochroleucous 

 corollas, are referred by Smith to var. parishii C. P. Smith (L. parishii 

 Eastw.). (See footnote 66, p. 434, Smith, p. 139.) 



12. Lupinus huachucanus M. E. Jones, Contrib. West. Bot. 12: 10. 



1908. 



Lupinus platanophilus M. E. Jones, ibid. 17: 29. 1930. 



Chiricahua and Huachuca Mountains (Cochise County) , Santa Rita 

 Mountains (Pima County), 5,000 to 6,000 feet, pine woods, March to 

 May, type of L. huachucanus from the Santa Rita Mountains (Jones 

 in 1903), type of L. platanophilus from the Huachuca Mountains 

 (Jones 26135). Southern Arizona and Chihuahua. 



The plant resembles L. concinnus, but is readily distinguished by its 

 ciliate keel and racemes surpassing the foliage. A specimen from the 

 Chiricahua Mountains (Price in 1894), with exceptionally narrow 

 leaflets, was referred by Smith (see footnote 66, p. 434, Smith, p. 124), 

 to L. chihuahuensis Wats., but that species, although evidently related 

 to L. huachucanus, differs from it in its much more sparsely pubescent 

 herbage, interrupted-verticillate inflorescence, larger flowers, and 

 appressed or subappressed pubescence of the pedicels and calyx. 



13. Lupinus aduncus Greene, Pittonia 4: 132. 1900. 



F Carrizo, Tunitcha, and Lukachukai Mountains (Apache County), 

 Jacobs Lake (Coconino County), 5,500 to 9,000 feet, June to Septem- 

 ber. Wyoming and Utah to New Mexico and northern Arizona. 



14. Lupinus greenei A. Nels. in Coult., New Man. Bot. Rocky Mount. 



274. 1909. 



Lupinus oreophilus Greene, Pittonia 4: 135. 1909. Not 

 Philippi, 1891. 



This species is known definitely only from southern Colorado, but 

 specimens from Navajo Mountain, Coconino County, Ariz. (Darsie 

 in 1933, Peebles and Smith 13954), are referred here tentatively, having 

 the banner sericeous on the back, as described by Greene. They are 

 aberrant, however, in their very narrow, almost linear, acute leaflets, 

 resembling, in this respect, the type of L. marcusianus C. P. Smith, 

 which came from the Grand Canyon (Jones in 1920). (See footnote 

 66, p. 434, Smith, p. 137.) Darsie's specimen is aberrant also in its 

 sparse pubescence. 



15. Lupinus lemmonii C. P. Smith, Sp. Lupin. 127. 1939. 

 Apache Pass and Sulphur Springs, Cochise County (Lemmon in 1881, 



Rothrock 543), Santa Rita Mountains, Pima County (Pringle in 1884),
