mountains of California. — Flowers more or less smaller, and calyx- 

 teeth much shorter and less attenuated than in the preceding. 



55. A. Utahensis, Torr. & Gray, Bot. coll. Gunnison & Beckwith, 

 Pacif. R. R. Exped. 2, p. 120. Pliaca moUissima /3. Utahensis, Torr. 

 in Stansbury, Rep. p. 385, t. 2. Lanugiue implexa niveo-tomentosus, 

 humifuso-cajspitans ; foliolis obovatis seu orbiculatis ; floribus violaceis ; 

 legumine oblongo leviter obcompresso modice incurvo, cset. fere praj- 

 cedentis. — Utah, on the shores of Great Salt Lake. — Flowers rather 

 shorter, but otherwise as large as those of A. injiexus ; the calyx-teeth 

 rather as in A. Purshii ; the pubescence, &c. peculiar. On stripping 

 off the wool from the pods, they are seen to be not unlike those of A. 

 injiexus, except that they are less curved, and only a little sulcate at 

 the sutures, which do not meet to divide the cell. 



§ 18. Oocarpi. Legumen chartaceo-coriaceum, ovatum, vesicario-in- 

 fiatum, estipitatuni, glabrum, sutura dorsali obsolete ventrali mani- 

 feste intrusa. — Glabrati, e radice perenni erecti, foliosi ; stipulis 

 discretis liberis ; foliolis oblongis ovalibusque nunc retusis. Flores 

 in racemo spiciformi plures albi seu albidi, semipoUicares ; calyce 

 brevi. Legumina erecta, nee ultrapollicai'ia. 



56. A. CooPERi, Gray, Man. Bot. N. U. S. ed. 2, p. 98. Phaca 

 neglecta, Torr. & Gray, Fl. 1, p. 344. Ultrapedalis, foliosus ; foliolis 

 oblongis ; floribus confertis mox reflexis albis ; calyce nigricanti-pube- 

 scente, dentibus subulatis tube brevioribus ; legumine ovato-globoso 

 sub-obcompresso antice posticeque leviter sulcato, sutura dorsali intus 

 prominula, ventrali satis introflexa. — W. New York to Wisconsin 

 along the Great Lakes. Legume lined with cobwebby hairs which 

 traverse the cell. 



57. A. OOCARPUS. A. CrotalaricE (in tab. crotalcmoides), Torr. 

 Bot. Mex. Bound, p. 56, t. 17, non Phaca Grotalarice, Benth. Elatus 

 (4 - 6-pedalis) ; foliolis ovalibus parvulis crassiusculis ; floribus paten- 

 tibus in racemo sublaxo ; calycis albido-puberuli dentibus brevissimis ; 

 legumine oblongo-ovato acuto antice solum leviter sulcato sectione 

 transversa circulari, sutura dorsali intus vix prominula, ventrali intro- 

 flexa. — Mountains east of San Diego, California, Dr. Parry. — Le- 

 gume rather firmly coriaceous, with a somewhat lateral or oblique 

 contracted insertion, within glabrous. 



§ 19. Inflati. Legumen membranaceum, vesicario-inflatum, globosum, 

 oviforme, vel semi-ovatum, SEepius magnum, tenuiter reticulatum.
