]^5Q LEGUMINOS^. Astragalus. 



Hills and plains, from around San Francisco Bay to Santa Barbara Co. ; the variety about San 

 Francisco Hny, iiiulijcs, Kcllixjij or JJuldr.r. If J'/uuut CroOdaritc, i. e. tiio H)>C(inieu of roullor, 

 was really collected '' ii.-ar Monterey," it is most pmhuhly a |iuli(isi'cnl and icwer-llowerod form 

 of this, with broad and less numerous leaflets. But .several ol Coulter's [liauta said to come fmm 

 Monterey nmst have been gathered on llio way thither in the southeastciu part of the Stole, or in 

 Arizona. 



20. A. Menziesii, I uay, 1. o. Villous witli whitish hair.s, or soon green and 

 almost glabrous : steins erect or decumbent, 1 to 4 feet high : stipules broader and 

 less pointed, all but the uppermost united on the side ot" the stem away from the 

 leaf: leaflets and dense spicate raceme as well as flowers nearly as in the preceding: 

 pod similar, but larger (an inch and a half or more long) ami more bladdery, the 

 walls thin-membranaceous. — Phaca densifolia, Smith; Hook. Ic. PI. t. 282, excl. 

 syn. Nutt. P. Nuttallii, Torr. c"t CJray, Fl. 



Meadows and sandy tields, San Francisco Bay to Santa Barbara near the coast. 



== = == Stipules scarious or thin-membranaceous, mostly suhuhite : peduncles shoiier 

 thxin the leaves and rather few-Jloiuered : corolla hardly twice the length of the calyx 

 (about 4 lines long), yellowish-ivhite or cream-color. 



21. A. macrodon, Oray, 1. c. Villous-canescent, at least when young: stems 

 a foot or two high : U'alluts in numerous pairs and mostly crowded, obloug-lineur 

 (from a third to an ini.li long) : llowers crowiled, soon rellexed ; calyx-teeth slonder- 

 Kubulate, as long a.i the campanulate tube, little shorter than the corolhi : niatun^ 

 poll not seen. — Phaca macrodon, Hook. <k Arn. 



Near San Franscisco or more probably Monterey, Douglas. More specimens are needed. 



22. A. Douglasii, Clroy, 1. c. Cinereous-puberulent, almost glabrous in age : 

 stems ascending, a foot or so in height : leaflets in rather numerous pairs, linear or 

 linear-oblong (a third to three quarters of an inch long) : spike (half an inch to an 

 inch long) 10 - 20-flowf,red : (udyx-teeth subulate, from half to three fourths the 

 length of the campanulate tube: ])od thin-])laddery, gibbous-ovoid, H to 2 inclu.'s 

 long. — Phaca Douglasii, Torr. & Uray, V\. 3iG. 



Gravelly beds of streams near the coast, San Francisco to San Luis Obispo. 



-h+ ++ Smaller pods {((boat half an inch long), fetv - several-seeded : stems low or spread- 

 iitg : jlower only a quarter of an inch long. 



23. A. Hornii, Gray. Glabrous or minutely pubescent : stems slender, ascend- 

 ing : leaflets about 21, narrowly oblong (4 to 7 lines long): peduncle surpassing 

 the leaves : flowers numerous in a dense head or short sj)ike, which is equally dense 

 in fruit : calyx-teeth subulate, about the length of the canq)anulate tulie : corolla 

 yellowish-white, slraigiitish : pods ovate from a broad base and gradually acumi- 

 iiate, straight, villous-pubescent, 10 - 15-see(led. — Proc. Am. Acad. vii. 398. 



Eastern side of the Sierra Nevada, in Owen's Valley {Dr. Horn), and at Bakerbtield, to S. 

 Utah. Said to be one of the sheep-poisons. 



24. A. Pulsiferee, Gray. Whitish-villous : stems numerous in a tuft and })ro- 

 cumbent, slender, branching: stipules slender-subulate: leaflets 5 to ll,obovate- 

 cuneate, mostly retuse, 3 or 4 lines long : peduncles not longer than the leaf, rather 

 loosely 3 - 5-flowered : flowers pedicelled : calyx-teeth linear-filiform, twice the 

 length of the campanulate tube, about the length of the keel of the incurved white 

 and purple-tinged corolla : the narrow wings and especially the standanl (notched 

 at the apex) much longer: pod ovate-inflated and incurved, villous-pubescent, 3-8- 

 seeded. — Proc. Am. Acad. x. 69. 



Gravelly hills and hanks. Sierra and Plumas counties, ^frs. Pulsifc.r Aracs, Lemmon. The pods, 

 although small (barely half an inch long), as in the inflated-fmited section ; but otherwise, in 

 aspect, mode of growth and size, wholly dilfoent. 



A. PUBiCNTissiMUS, Gray, Proc. Am. Acad. vi. 209, is nearly related to the preceding, and is 

 probably perennial ; but it has short stems, much broader stipules, leaflets hardly narrowed
