 Plants almost stemlesa. Flowers mostly white. ISl Purshii. 



151 Astragalus Wcbberi Grny Eot. Cal. 1 154 (1876). Pods uith 

 holh sutures raised externally and the ventral much thickened when 

 dry, narrowly-oblong but a little narrowed at both ends, smooth, 5-7 

 la.n. high, lU-12 mm. wide, generally sulcate to the middle but not at 

 liie ends, tips broadly triangular and a little laterally flattened, cross- 

 section reniform to oblately obovate. Flowers white, 1.5 cm. long, 

 Sj)! eading. Banner elongated and almost erect, narrow, 8-9 mm. long. 

 Wings narrowly oblong, arched to 45 degrees, rounded, about 4 mm. 

 shorter than banner and as much longer then keel or less. Keel about 

 4 m;n. high, straight the end abruptly erect and forming nearly a rigb.t 

 angle, purple. Calyx tube about 7 mm. long, attached in line with the 

 ba-e, the upper side a little arched, the lo.ver side straight, the teeth 

 .■=ubulate and nearly half as long as the tube. Bracts as long as to a 

 haif longer than the short pedicels, lanceolate to ovate. Peduncles 

 longer than the leaves. Heads rather denselj' 9-20 flowered. Pro;;er 

 petioles rarely as long as the lowest leaflet. Leaflets 5-10 pairs, nar- 

 rowly oblong-oblanceolate, with cuneate and long-petiolula te ba.<^e, 

 not over 2 cm. long, not retuse. variabb' silvery-pubescent. This oc- 

 curs sparingly on hillsides in the Sierras near Sierra Valley Ca:ii'ornia 

 ill the -Middle Temperate life zone. It is probably only a marked form 

 of -\. cibarius. 



152 Astragalus cibarius Sheldon Minn, Bot. Stud. 9 149 (1894). A. 

 ioianthus Waison in part, as to Utah material. Pods puberuient to 

 almost smooth, rather abruptly narrowed and substipitate at bas^e the 

 stipe from barely longer than wide to 2 mm. long and not jointed to 

 the calyx, pods I'rom nearly straight to arched almost to a half circle, 

 2.5-4 cm. lorg. 7-10 mm. wide, 5-8 mm. high, oblong to broadly h'ncar, 

 fir.e^y corrug ited, rot mottled, tip from a little to much flattened, tri- 

 angular, walL^ about 3 mm. thick when fresh the inner one woody, 

 cross section from nearh' round to almost didymous by being much 

 obc.nivipressed. tl'.e normal cross-section is nearly co-shaped but the 

 sutures not touching, and the ventral suture raised externally and not 

 intruded and only slightly thickened, dorsal suture raised externally 

 as a thin line when dry and intruded as high as wide in forms with 

 deltoid cross-.'^ection, pods often much sulcate along the middle. The 

 flov. ers purple, bluith when dry with lighter claws, albino forms rai e, 

 1.5 2 cni. long, almost sessile, with conspicuous lanceolate bracts near- 

 ly half - s 'ong as calyx. Banner ovate, about 1 cm. long, rather deep- 

 ly notched, with sid-es much reflexed below so that the banner seems 

 oblong, arched beyond the calyx tips to nearly and r.'ither sharply e- 

 recl, v.hite spot deep-purple- veined and conspicuous, blade deep- 

 purple below and ^hading to white above or purple throughout, a litt'e 

 sulcate. Wings from nearly as long as banner to 4-6 mm. shorter but 

 much longer and narrower than keel, nearly linear, very rounded, a 

 trifle narrow-ed in the middle and a little enlarged above, mostly about 

 straight, but .'on-elinc.'; arched to 30 degrees, variably purple at brse. 

 white above, rarely purple throughout, flaring at tip and the ends 

 turned to horizontal, obscurely erose or notched. Keel about 5 mm. 

 long and 4 mm. high, the base straight and then abruptly arched to 

 erect and with tip very obtuse, rounded, and deep-purple. Calyx ni- 

 grescent, with tube about 4-5 mm. long and nearly half as high, cleft 

 deejier above, and triangular teeth about one fourth as long. Pedun- 

 cle<= normally shorter than the leaves, rarely longer, stout, with the 

 pods shortly rncemo<se. Leaves with pe'^ioles mostly twice as long as 

 the lov.er leaflets. Leaflets about 9-12 pairs, from oval-ovate or ob- 

 ovate to cuneatc-oblong. mostly notched, about 1 cm. long, rarely 2 

 cm. long when over developed, slendcr-petioled, green above, not
