267 Leptocarpi. 
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. j 
Pods single or few. 240 Nuttallianus. 
3A2B. Pods equally but not greatly arched, breadly 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 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 subuiate 
teeth half as long as tube. Bracts triangular, 2 mm. long, hyaline. . 
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 em. long, 
about 7 mm. wide. Stipules 4 mm. long, reflexed, green. Stems 
many, filiform, delicate and long, rather fiexuous, nearly prostrate, 
with internodes 4-7 em. long. San Francisquito Lower California 
Brandegee. i 
. 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, narrowly elliptical, 4 mm. long, 2 mm. wide, - 
rounded at both ends and shortly petiolulate. Internodes about 2.5 — 
cm. long. Sierra de Laguna, Lower California, blooming in January.
