rachls with a few filiform leaflets. Stipe sometimes twice the calyx. 

 Otherwise as in the var. magnus. More common. 



55. Astragalus vestitus (Benth.) \Yatsou Bib. Index 202 (1878). 

 Phaca vestita Benth. Bot. Suljih. 13 (1811). This antedates A. ves- 

 titus Boissier A. Heldr. Diag. PI. 1 pt. 9 98 (18h9). Tra?:acantha 

 Kuntze, A. anemophilus Greene. Pods fror- "^-rly oval tT h-xlfoval, 

 rather angled than pointed at both ends, iIih tip be ng deltoid and 

 very short in the type, variously spreading with dorsal suture barely 

 sulcate and ventral decidedly so, often to one-third the depth, hoary to 

 minutely pubescent. Flowers nearly in heads in the type, about 1 

 cm. long, wide and stubby, white or rarely purpled tipped, soon re- 

 flexed. Banner fleshy below and with thick claw, the tip oval and 

 vei-y phort, arched remote from the calyx to nearly erect and with 

 sides reflexed a trifle as a mere rim around the edge, the blade 5-7 

 mm. long, scarcely longer than the wings and keel. Wings oblong, 

 nearly straight, rounded, little arched, veiny, abo it 1 mm. or leas 

 longer than keel. Keel with straight base and then abruptly erect, 

 the til) bi-oad iuid \cr:' obtuse, about H mm. high, purple. Calyx tube 

 siiort-campanulate, about 4 mm. long and 3 mm. high, oblique at base 

 and rather truncate, inserted near the middle, cleft deeper above, 

 hoary, the triangular teeth about half the tube. Pedicels in the 

 type almost none. Petioles absent or 3 cm. Inns;. Leaflets 10-14 pairs, 

 oval to elliptical, truncate to acutish, 1-2 cm. long. Stipules connate. 

 Pubescence white-woolly in the tyiie. A very variable species. Mag- 

 daiena Bay I.,ower California. 



Astragalus vestifs var. Mp-^^i-^s'' (Orny Proc. Am. Af^d. R 217 

 (18G4) as species). Phaca densifolia Smith, A. densifolius (Sm.) Torr. 

 Phaca Nuttallii T. & G. Pods papery and rather translucent. 3-5 cm. 

 long, 2-3 cm. wid^^ and high, obliquely ovate to oval, pubfrulent, keeled 

 ventrally and rather sulcate. reflexed. short-racemose. Flowers cream- 

 colored, thick, about 1.2 cm. long, reflexed. Calyx tube shortly-cylin- 

 dric-campanulate, about 4 mm. long and nearly as high, cleft deeper 

 above, slightly nubescent; teeth about half as long as tube and subu- 

 late from a deltoid base. Pedicels slender, 3-4 mm. long, equaled or 

 a little surpassed by the the very thin and hvaline and narrow 

 bracts. Peduncles 1-1.5 dm. long, mostly longer than the leaves and 

 lon.-^er than the floral rachis. Leaves sessile or the lower only short- 

 petioled, about 1 dm. lone. Leaflets 15-19 pairs, elliptical with a cu- 

 neate base, rounded to notched, 1-2 cm. long. Stipules connate ex- 

 cept at the uppermost nodes, papery and conspicuous. Stems erect 

 to decumbent, from a wnody base, rather stout. 2-3 feet long. Pubes- 

 cence thinlv woolly and soft throughout except on the calyx. Common 

 nn open hill sides and plains from San Francisco southward along 

 the coast. 



Astragalus vestitus var. Franciscanus (Sheldon Minn. Bot. Stud. 

 9 133 (1894) as species). A. Franciscanus var. longulus Sheldon. A. 

 Crotalarise var. virgatus Gray. Phaca Frauciscana (Sheldon) Heller. 

 Stipules connate only near the base of the stems. Pods many an'' 

 often erect. Pubescence ashy or minute but evidently the rudiments 

 of woolly hairs. Calyx lobes rather subulate and as long as tube. 

 Same range as the var. Menziesii and freely intergrading. Thi? 

 variety is more strict and less inclined to be decumbent. 



56. Astragalus Porrcnensis .Tones Cont. 10 59 (1902). Pods abou' 

 5 cm. long and nearly 3 cm. high and wide, about half oval, conspic- 

 uously oblique, very blunt with a very short and deltoid tip not longe- 

 than wide, smooth when mature, ascending in dense swabs at th- 

 ends of stout peduncles which are about 1 dm. long and much shorte ■ 

 than the leaves. Flowers and calyx as in A. Menziesii in she-' 

 spikes shorter than the peduncles. Leaves about 2 dm. long, sessil-^ 

 Leaflets about 2 cm. long, oblong, a trifle wider below, truncate ;- ' 

 tip and cuneate and long-petiolulate at base. Stems many and tuftel.
