267 Lcptvcarpi. 



3A. Flowers few and inclined to be racemose, with sharp keel (keel 



sometimes obtuse in A. Nuttallianus) and wings inclined to be 



lobed. Pods linear. 



3AB. Pods arched most near base, the tip mostly erect. Flowers 



single to few^ at or near the tip of the peduncle and inclined 



to be clustered, spreading. 



Pods single or few. 240 Nuttallianus. 



3A2B. Pods equally but not greatly arched, broadly linear, 1.5-2 

 cm. long, mostly inverted on a twisted pedicel, taper-pointed, 

 laterally flattened, somewhat narrowed below, racemose and 

 rather distant, ventral suture a fine rib, cross section narrowly 

 triangular-cordate. Peduncles conspicuously longer than the 

 short leaves. Leaflets broad and notched. Keel abruptly 

 narrowed to a subulate beak at the upper corner. Wings 

 lobed or broader above. Plants about as well placed in 

 Oxytropis as in Astragalus. 



Internodes few and long. 241 acutirostris. 



Internodes not few, short. 242 nothoxys. 



234. Astragalus Francisquitensis Jones Cont. 7 666 (1895). 

 Pods linear-oblong, nearly straight, about 12 mm. long, 2-3 mm. 

 wide, obtuse, laterally flattened, chartaceous, with only a dorsal 

 groove. Flowers 10-15 or less, in short raceme-like head or cluster, 

 ascending, about 1 cm. long, narrow. Banner 5 mm. long, oblong, 

 narrow, ascending 45° beyond calyx tips, with sides reflexed about 

 1 mm. wide. Wings linear, straight, 1 mm. wide, as long as banner 

 and 3 mm. longer than keel. Keel short, very obtuse and rounded. 

 Calyx tube hyaline, nigrescent, narrowly campanulate, about 3 mm. 

 long, rather obliquely attached, hardly 2 mm. high, the subulate 

 teeth half as long as lube. Bracts triangular, 2 mm. long, hyalme. 

 Pedicels slender, 1 mm. long, as long as bracts in fruit. Peduncles 

 nearly 1.5 dm. long, strict. Leaves about 1 dm. long, with petioles 

 1.5-2 cm. long, but very short on the upper leaves. Leaflets 8-12 

 pairs, oblong-obovate to elliptical, finely petiolulate, 1-1.2 cm. long,, 

 about 7 mm. wide. Stipules 4 mm. long, reflexed, green. Stems 

 many, filiiorm, delicate and long, rather flexuous, nearly prostrate, 

 with internodes 4-7 cm. long. San Francisquito Lower California 

 Brandegee. 



Astragalus Francisquitensis var. Lagunensis Jones Cont. 8 11 

 (1898) and Cont. 10 61 (1902). ' Like the type but pods deeply sul- 

 cate, with cross section triangular-cordate and tip pungently acute 

 with point 1 mm. long. Flowers the same. Leaves 2-5 cm. long. 

 Leaflets 7-8 pairs, naiTowly elliptical, 4 mm. long, 2 mm. wide, 

 rounded at both ends and shortly petiolulate. Internodes about 2.5 

 cm. long. Sieri'a de Laguna, Lower California, blooming in January. 



235. Astragalus Lindheimeri Gray PL Wright 1 52 (1852). 

 A recticarpus Wood. Hamosa Rydberg. Tragacantha Kuntze. Pods 

 much like those of A. succumbens, 2.5-4 cm. long, about 5 mm. high, 

 1 mm. wide, contracted at base into a pseudo-stipe or nearly sessile, 

 the triangular tip about in the middle of the end and ventral suture 

 convex below it and then concave to the base, 2-celled at least to 

 the middle, narrowly sulcate dorsally, ventral suture raised and 

 forming a strong rib, with cross section Y-shaped, nearly erect at 

 tip but pedicel horizontal or reflexed. Flowers 4-12, congested, 

 about 12 mm. long. Banner nearly round, about 1 cm. long, pur- 

 ple-edged for 2 mm. in width, arched in gentle curve to 10-20° be- 

 yond calyx. Wings oblong, a little arched, rounded and blunt, 

 2-3 mm. wide, 2 mm. longer than keel and about 1-2 mm. shorter 

 than banner. Keel purple-tipped, about 8 mm. long, then abruptly 

 erect and tip deltoid and 4 mm. high. Calyx tube nearly hemispheri- 

 cal, about 2 mm. long, rounded at base and about equally inserted, 

 a little oblique at tip, with thread-like teeth very lax and about twic^-
