colours in the petals," and "its loose, but not stracrgly, mode of 

 growth," rather strengthens the supposition. The pods of varii- 

 color are more nearly smooth than are those of the other species. 



Whatever may be the true status of riviilaris^ it certainly 

 belongs to the Arborei and not to the Latifolii where Watson 

 placed it. 



Besides A. lignipcs and L. riviilaris the following names 

 belong to the Arborei: 



'^ LupiNUS ARBOREUS Sims, Bot. Mag.//. 682. 1803. 



The native country of this species was unknown when it 

 was publislied, and for .some time the type was thought to have 

 come from South America. It was no doubt collected at Mon- 

 terey, California, where it is plentiful in sand near the coast. 



LUPINUS EXiMius Davy, Erythea 3: 116. 1895. 



Although the type of this is in the herbarium of the Uni- 

 versity of California, Jepson does not mention it in his Flora of 

 Western Middle California, either as a valid species or as a syn- 

 onym. It is certainly distinct and is a handsome large violet 

 flowered species, originally collected "above Lake Pilarcitos, San 

 Mateo Co., Calif." It is apparently also found on Mt. Tamal- 

 pais north of San Francisco. The only montane species in the 

 group. 



LUPINUS PROPIXQUUS Greene, Erythea 1: 126. 1893. 



Originally collected at Santa Barbara, California, and said 

 to occur as far north as Point Reyes. 



\/ Lupixus VARiicoLOR Steud. Nomen. !<J: 78. 1841. 



Lupinus versicolor Lindl. Bot. Reg. pi. 1970; not Sweet, 



Brit. Fl. Gard. 'Z'. pi. 12. 

 Li(pimis franciscanus Grttnt, Pittonia 1: 64. 1887. 

 Originally collected by Douglas, undoubtedly about Mon- 

 terey, where it is plentiful. Jepson, in the second edition of his 

 Flora says "too near the next" {L. Chamissoms), which does not 

 at all resemble it, being related rather to L. albifrons, which as 

 I see it, does not 1:)elong to the Arborei.
