APPENDIX D. — BOTANY. 885 



Fendl. p. 16. Malva involucrata^ Torr. and Gr. Fl. 1, p. 226. 

 Upper waters of the Platte. The large tapering root is said to be 

 edible. 



ViciA AMERICANA, Muhl. — Valley of Salt Lake, June 1. 



CiCER ARIETINUM, Lin. — Sandy bottom land in the Valley 

 of Salt Lake ; probably introduced. This plant has also been 

 found by Dr. Pickering on the banks of the Kooskooskee, or Clear 

 Water, in Oregon ; and I have received it from Southern California, 

 where it was doubtless taken by the Spaniards. It is a little 

 remarkable that it should now be found apparently wild in the 

 interior of Oregon and in the valleys of Utah. 



Phaca mollissima, Nutt. in Torr. and Gr. Fl. 1, p. 350. 

 Astragalus pur shii, Dougl. in Hook. Fl. Bor., Amer. 1, p. 152. 



Var. ^ UTAHENSIS ; foliolis. 6-8, jugis, obovatis ; pedunculis folio 

 longioribus. Shores and islands of the Salt Lake. This plant 

 is abundant in the Territory of Utah, and I have not received it 

 from any other region. It differs from the ordinary form of P. 

 mollissima : and if there were not what appear to be intermediate 

 states of it, I should consider it a distinct species. It is less 

 branched, and has more numerous leaflets than the var. 3. The 

 flowers are violet, four to six in number, in a short spiked raceme. 

 The nearly mature legume' is densely clothed with long woolly 

 cream-coloured hairs, and very closely resembles that of P. mol- 

 lissima. Our plant has much the appearance of Astragalus gla- 

 reosuSy Dougl. (^A. argophgllus, Dougl.,) and which, I suspect, is 

 a Phaca, but the leaves and fruit are different. 



Plate II. Phaca mollissima, var. utahensis of the natural size. 

 Fig. 1, a flower. Fig. 2, the wings and heel. Fig. 3, the 

 stamens. Fig. 4, mature fruit of the var. a- Fig. 5, cross 

 section of the same. Fig. 6, immature fruit of var. utahensis. 



Astragalus adsurgens, Pall. ? — West shore of the Salt Lake, 

 in sandy soil. Flowers white, shaded with purple. This plant 

 seems intermediate between A. adsurgens and A. striatus, Nutt. 

 The legumes were not found. May 1. 



OxYTROPis LAMBERTi, Pursh.^— Upper waters of the Platte, &c. ; 

 frequent. 



Hedysarum mackenzii, Richards. App. Frankl. Journ. ed. 2,
