Leaflets 8-10 pairs, narrowly oblong, obt ise to notched, cuneate below 

 and long-petiolulate, 5-15 mm. long, net folded, thin, smooth. Stems 

 ascending, about a foot high, very many, almost simple. Stipules 

 triangular, small, hyaline, thin, the upper reflexed. Growing along 

 irrigation ditches and moist bare bottoms and among willows in gravel 

 and clay, from Richfield Utah to the head of the Sevier. My material 

 from Willow Spring south of Lee's Ferry is probably this species, 

 blooming in summer. 



52. Astragalus serpens Jones Cont. 7 641. 644 (1895) Phaca Ryd- 

 berg. Pods oval-ovate, 2-2.5 cm. long and about 1 cm. wide and high, 

 round in cross section, barely sulcate ventrally. papery and much 

 mottled but not translucent, conical beaked, the beak not longer 

 than high and minutely apiculate, rounded at bnse, the stipe hardly as 

 long as calyx tube. Flowers greenish-purple, about 7 mm. long, rarely 

 half a dozen and pods mostly single to a peduncle, the raceme about 

 1 cm. long and the stout peduncle only a little longer. Banner nearly 

 round, about 3 mm. long, j\ist equaling the wings .in.d keel, abruptly 

 arched to 110 degrees. Wings obovate-oval, ver>' oblique, about 3 mm. 

 wide and 4 mm. long, just the shape of the keel. Keel blunt, the 

 base a trifle arched, the tip incurved to erect and vv-ith a minute boss, 

 about 3 mm. high. Calyx narrowly campanulate, the tube 3 mm. long, 

 teeth subulate, 2 mm. long. Bracts hyaline, about 2 mm. long, ovate. 

 Pedicc^ls, 2.-4 mm. long, reflexed or spreading. Peduncles axillary. 

 Leaves 3-4 cm. long, narrow, thick and stiff, many (the internodes 

 rarely 2 cm. Iqng), the relatively stout petiole about half the whole. 

 Leaflets about 6 pairs, elliptical to oval, folded, thick, rounded and 

 very obtuse, about 5 mm. long, contiguous. Stems csespitos^" and 

 many from a thick and woody root, prostrate, freely branched, relative- 

 ly ctcnit, rarely 2 dm. long. Stipulps brown and thin, deltoid, con- 

 spicuous, not connate, 3-4 mm. long. Whole plant ashy with short 

 loosely appressed and rather tangled hairs, the calyx black-hairy. 

 Lea Pass and Belknap Mt. Utah on hie'h rocky ridges. Apparently 

 in the Elk Mts. Utah. The r^rterial of A. triflorus from the San 

 Rafael Swell Utah much resembles this but the pods are sessile and 

 leaflets narrow. Middle Temperate life zone. Blooming in July. 



53. Astragalus nutans n. so. .Pods as in A. serpens but trans- 

 lucent and only a little blotched, n°arlv pi^bose. Flowers nurpl^ 

 with claws about 1 cm. long, few and shortly racemose, horizontal 

 to reflexed. Banner about 5 mm. lone, oval, abriptly arched at end of 

 calyx to 45 degrees, with sides reflexed about 1 mm. wide below, 

 white spot purple striked. Wines obliquely nbovate, rounded. 2 mm. 

 shorter than banner and 1 mm. longer than keel. Keel with straight base 

 and then rounded to a little more th'in erect, the tip nearly square 

 at the corner, about 3 mm. high. C'-.lyx tube campanulate, about 

 3 mm. long and 2 mm. high, the base straight, the upper side arched, 

 inserted a little below the middle at the fleshy base, cleft deeper 

 above and oblique at tip. the teeth triangular and about one-half t" 

 one-third the tube, pubescent with white and blank hairs intermixed 

 and closely aPT^ressed. Pedicels stout, 2-4 mm. long in fruit, rathe' 

 longer than the ovate bracts. Peduncles 3-4 cm. long but shorter 

 than the leaves, the floral rachis about half as long, in the uppe'- 

 axils. Leaves 4-5 cm. long, only the lower petioles as long as lea' 

 rachis, many (the internodes 1-3 cm. long). Leaflets 3-6 pairs, el- 

 liptical, cuneate below, obtuse, 1-1.5 cm. long, often folded, not very 

 thick. Stems 1-3 dm. long, rather slender, branched throughout 

 several from the tip of a slender erect not woody root, blooming the 

 second year. Stipules "mail, triangular, rather hyaline, about 3 mm. 

 long. Whole plant minutely ashy with closely appressea stralgb" 

 halrs. Growing in sand and blooming in May. Tropical. Providencp 

 Mountain eastern California. This has the habit of A. triflorus var.
