Genus ASTRAGALUS Tournefort. 

 L, Gen ed 1, 215 (1737). 



Ann or per herb or sometimes woody 

 at base, with unequally pinnate Ivs, 

 persistant stipules, and rather sm fls 

 arranged in axy spk or racemes: ex 5- 

 toothed: pet with nar blade and slender 

 claw: keel obtuse: sta diadelphous: 

 stig terminal, minute: pod various, 

 coriaceous and turgid, or thin and 

 bladdery-inflated, 1-celled, or becoming 

 2-celled by intrusion of one or both 

 sutures: sds few to many, sm, on slen- 

 der funiculi. Rattle-weed, loco-weed. 

 A. ACUTIBGSTBIS Wat 20:360. 



"Ann, slender, resembling A. Nuttal- 

 lianus: Ifts 5 or 6 pairs, retuse, 2 or 3" 

 Ig: racemes much exceeding the Ivs in 

 fr: ex a line Ig, the slender teeth about 

 equalling the turbinate tube; cor w'ish, 

 2" Ig, the keel with an acute oft as- 

 cending beak: pods (1-5) scattered on 

 the rhachis, like those of A. Nuttalli- 

 anus, but the ventral suture nearly 

 straight, 8" Ig. Near Brown's Ranch, 

 Mohave Desert, by Parish Brothers, 

 May, 1882, and on dry rocks above the 

 Calico Mines, near Fort Mohave, by J. 

 G. Lemmon, May, 1884. Closely allied 

 to A. nothoxys. G but with much sm'er 

 fls and ex." Wat 20:360. 

 A. AZ.BENS Greene, Cal ac b 1:156. 



"W thruout with a sh, appressed, 

 silky pubescence: branches spreading, 

 less than 1 Ig, from a per rt: Ifts in 

 about 4 pairs, obovate, obtuse, 3-5" Ig: 

 raceme few-fld: pedicels very sh: ex- 

 teeth subulate, equaling the tube: cor 

 4" Ig, p: pod oblg, slightly compressed, 

 falcate-incurved, silky pubescent. Mo- 

 have Desert, My, 1882, S. B and W. F 

 Parish, No. 1274. Perhaps nearest A. 

 Cobrensis, but that is a green and glab- 

 rous, considerably sm'er plant with 

 straight pods." Greene, Cal ac b 1:156.
