Inflati 113 



pubescence very variable. Stipules rather scarious, with deltoid base 

 and subulate tip, rarely 5 mm. long. Stems rather prostrate and with 

 ascending tips, many from a thick and fleshy root, flexuous, 2-3 ft. long, 

 growing on flats where it is rather alkaline. Being the first green 

 things in the spring this species has the reputation of being a loco 

 weed. From the southern San .Joaquin valley to southern California, 

 and San Pedro Martir, Lower California, Lower Temperate life zone, 

 in the interior, mostly. 



Astragalus Douglasti var. Parishii (Gray) Jones Cont. 8 6 (1898). 

 A. Parishii Gray Proc. Am. Acad. 19 75 (1883). Pods oval to oblong, 

 oblique, usually apiculate, often 5 cm. long, smooth to minutely pubes- 

 cent, nearly round in cross section. Flowers white. Banner 2 mm 

 longer than keel, 1 mm. longer than wings. Wings oblanceolate, nar- 

 rower than keel. Keel about 4 mm. high. Calyx teeth from half as 

 long as tube to very short. Leaflets 7-10 pairs, elliptical, obtuse, 2-3 

 cm. long, silvery-pubescent below. Stems about 2 ft high. From 

 Antelope Valley southward along the mountains. 



Astragalus Douglasii var. glaberrimus Jones Cont. 7 645 (1895). 

 Pods hall-oval, shortly and triangular flat-beaked, 2.5-4 cm. long, round 

 in cross section, refiexed. Flowers 6-10. Racemes very lax. Pe- 

 duncles 1-1.5 dm. long including the rachis which is two-thirds the 

 whole. Leaflets about 7 pairs, linear-lanceolate, very sharp-pointed, 

 1-2 cm. long, 2 mm. wide, distant. All but the very uppermost leaves 

 petioled. Plants rarely a foot and half high, rather bushy branched at 

 base. San Fernando and Los Huevelos Lower California, Brandegee. 



Astragalus Douglasii var. piscinus Jones Cont. 7 645 (1895) and 

 Cont. 10 61 (1902). Pods obliquely ovate-oblong, 2 cm. long, 1.2 cm. 

 wide, rounded at base, papery, sulcate ventrally, shortly acute, round 

 in cross section, nearly smooth, ascending. Flowers purple, 1 cm. 

 long, loosely spicate-racemose, almost sessile. Banner ascending 

 sharply to 45 degrees remote from calyx tips, with sides reflexed. 

 Wings about 7 mm. long, lanceolate, arched 30 degrees, a trifle longer 

 than keel. Keel 1 mm. shorter than banner, 7 mm. long, large, arched 

 to erect. Calyx broadly campanulate, 2 mm. long and wide, twice as 

 long as the triangular teeth. Pedicels very short and a half shorter 

 than the ovate bracts. Peduncles floriferous on the upper third, the 

 racemes 5-10 cm. long, stiff. Leaves sessile. Stems erect. Stipules 

 minute, not connate. Whole plant almost smooth. Lagoon Head Lower 

 California, Palmer. 



Astragalus Douglasii var. Tejonensis Jones Cont. 7 644 (1895) and 

 Cont. 10 61 (1902). Pods mostly ascending, half-oval-ovate, 2.5-4 cm. 

 long, 2-3 cm. wide, nearly round in cross section, variously reticulated, 

 nearly smooth when ripe. Flowers like the var. Parishii but banner 

 not elongated. Keel tip but little incurved and broader. Calyx lobes 

 subulate and half as long as tube. Flowers racemose, usually ascend- 

 ing, often distant. Floral rachis in flower 5-7 cm. long, in fruit 10-15 cm. 

 long. Peduncles and rachis 1-2 dm. long, finely §jilcate as are the 

 stems. Leaves and leaflets as in Parishii but leaves 7-13 cm. long and 

 ascending. Leaflets 10 pairs, not over 2 cm. long, elliptical to oblong- 

 lanceolate, rounded at tip, 4-5 mm. wide. Proper petioles present. 

 Plants green throughout seemingly but really with the same minute 

 pubescence but less evident. It is readily separable from Parishii by 

 the small-cream-colored flowers, long calyx lobes, broad leaflets and 

 Tre^^n appearance. This is the common form along the mountains north 

 •^f the San Bernardinos. A. Douglasii can be separated from A. macro- 

 don only by the pubescence. 



63. Astragalus allochrous Gray Proc. Am. Acad. 13 366 (1878) A. 

 Wootoni Sheldon. Pods half-oval, thin-chartacfous, slightly if at all 

 sulcate, apiculate and barely acute, faintly and rather closely reticu- 

 lated, apparently smooth when ripe but really minutely puberulent, 

 about 1.5 cm. high and 3 cm. long, with ventral suture convex only
