a quarter as long as tube. Bracts small and subulate. Peduncles at 
least as long as the leaves. Leaves 3-5 cm. long. Leaflets 6-8 pairs, 
linear-oblong and obtuse, long-petiolulate, 1-1.5 cm. long, ashy when 
young. Stipules linear-lanceolate, about 4 mm. long. Stems short 
and flexuous. Zacatecas Mexico. From the description there is little 
to separate this from A. Antoninus or gracilentus forms. 
157 Astragalus Antoninus \Vatson Proc. Am. Acad. 17 343 (1882). 
This differs in no particular from A. coriaceus except the stipitate 
pods being slightly sulcate dorsally. The flowers are about 2 cm. long. 
banner elliptical, about 7 mm. long, arched abruptly to 45 degrees at 
end of calyx teeth, about 4 mm. longer than keel and a little longer 
than wings. Wings and keel as in A. gracilentus. Calyx tube 
short-cylindric, about 5 mm. long, inserted on the lower corner, and 
the minute teeth triangular and hardly a quarter as long as calyx tube. 
The rather pubescent pods seem to be ascending or spreading. Saltillo 
Mexico, probably Socorro Co. New Mexico, Metcalf. 
158 Astragalus pinonis Jones Cont. 8 14 (1898). Pods straight or 
slightly arcuate below, short-stipitate, oblanceolate, shortly acute at 
both ends, 2 cm. long, 4-5 mm, wide and high, corrugated, coriaceous, 
somewhat inflated, with both sutures narrowed and rounded exter- 
nally, the ventral suture a little raised, neither suture at all intruded, 
pods reflexed, with ventral side nearly straight, the dorsal side convex. 
Flowers apparently purple. Banner oval and about as long as keel. 
Keel purple-tipped, about 5 mm. long, erect tip, straight, acute, pro- 
duced and nearly 3 mm. high, 2 mm. wide at base, as long as the ob- 
long wings. Calyx campanulate-cylindric, narrowed below, the tube 
a little over 2 mm. long, the subulate teeth 1 mm. long. Bracts trian- 
gular, 1 mm.long. Pedicels slender, reflexed, 4 mm. long. Pedun- 
cles 2.5-5 cm. long, shorter than the leaves, racemosely few-flowered. 
with rachis from half to as long as peduncles. Leaves 5-7 cm. long, 
short-petioled. Leaflets ‚linear, rounded at both ends, barely peti- 
olulate, 4-10 pairs, 1-1.2 cm. long, 2 mm. wide, not contiguous. Inter- 
nodes 1.5-2 cm. long. Stipules triangular, small, not over 2mm. long, 
distinct, not membranaceous. Stems rather slender. ashy-puberulent 
throughout, nearly erect. branched below, rounded, about 2 dm. long, 
wiry, green (as is the whole plant), but pubescence ashy and tangled. 
It has the habit of A, atratus and growing in similar places on gravel- 
ly benches at Frisco Utah. Lower Temperate life zone. It is pos- 
. Sible that when better known this may belong to the Lonchocarpi. 
. 139 Astragalus Neomexicanus Wootton & Standley Cont. Nat. 
Herb. 16 136 (1913). Pods thick-walled, round in cross-section, dense- 
-ly pubescent wheu young ‘only very immature pods known). Flowers 
purple, about 2 cm. long, several to many, in racemes which with the 
peduncles are 15-25 cm. long: Banner and wings longer than the 
rounded keel. Bracts linear, 4-6 mm. long. Pedicels 2-3 mm. long. 
Calyx campanulate, gibbous above, 7-9 mm. long, sparsely pubescent 
- with short black and white hairs, with subulate teeth about a third as 
‘long as tube. Leaves 10-18 cm. long. Leaflets about 20 pairs, villous 
with weak and spreading hairs, elliptical to ovate-lanceolate, acute, 
. 10-12 mm. long, smooth above. Stipules triangular-lanceolate, about 
lcm. long. connate. Stems a. foot long. ascending, branched from 
se, perennial. No. 690254 Nat. Herb.. from James's Canon Sacra- 
mento Mts. New Mexico, 7000.ft. alt., July 20 1899, Wooton. This 
seems to be A. gracilentns, but the poor material makes it doubtful. 
_ 160 Astragalus Sileranus Jones Cont. 2 242 (1891). Pods in the 
type almost leathery, but varying to almost papery in some forms, ^ 
. oblong-oval to globose, normally (in the type) rounded ^t both ends, | 
‚straight, horizontal, 1.5-2 cm. long, about 1 cm. wide and nearly as 
‚high, a little obcompressed, and slightly oblique, with flat and up- 
turned beak very short, and with dorsal suture a trifle intruded, and 
. pods about round cross-section, except for the shallow groove along 
the ventral suture, mottled and very finely cross-nerved, evidently in-
