132 Astragalus Parryi Gray Am. Jour. Sci. Ser 2 33410 (1862). 
Pods broadly sulcate ventrally, and narrowly and deeply so dorsally, 
much obcompressed and with dorsal suture a little produced, falcate 
to a half circle often, with cross-section about reniform or obcom- 
pressd to that of the figure ©, finely longitudinally- and cross-lined, 
with walls 1-2 mm. thick when fresh, densely short-hoary when young 
and long-shaggy when old. Flowers 6-10, 1.5 cm. long, wide. Ban- 
ner about reniform and deeply notched, about 1 em. long, with very 
short claw, abruptly arcuate at end of calyx tube to nearly erect, the 
sides much reflexed below to 3-4 mm. wide, finely and faintly purple- 
lined with branching veins. Wings oblanceolate and much rounded, 
about 3 mm. wide at tips, sometimes arched to nearly erect, often 
tinged with purple, a little longer than the keel, 2-6 mm. shorter than 
banner. Keel about 7 mm. long and 3'mm. high, abruptly arcuate to 
‘erect and with rounded tip which is 3 mm. wide and with a purple spot 
at the very end. Calyx tube 7-8 mm. long, 4-7 mm. wide, a little infla- 
ted, inciined to be alittle spurred above at the end and quite oblique 
but attached near the middle of the fleshy end, papery, long shaggy- 
hairy, mostly whitish but sometimes nigrescent, with subulate teeth 
about as long as tube and rather lax. Pedicels stout in fruit, 3-4 mm. 
long, ascending. Eracts green and hyaline, 4-10 mm. long, triangular. 
Peduncles shorter than the leaves, rarely 1 dm. long. Leaves 5 cm. to 
2 din. long, the lowest very much reduced, and with very small round 
and often notchcd leaflets, the uppermost leaves with elliptical leaf- 
lets 1-1.5 cm. long and apiculate to retu:e. Petio'es rarely a third the 
whole, tapering as wellas the long rachis. Leaflets rather distant, 
10-12 pairs, nearly smooth above, lonz-shazzy-hairy below, but pubes- 
cence sparse except on young parts or on plants growing in speciaily 
dry places. Upper stipules triangular and about 1 cm. long, green or 
hyaline below, the lower ones short and wide. Stems rather thick and 
succulent, often a foot long and with slender internodes, spreading 
from a rather much branched and woody crown. This grows among 
rocks in rather moist canons and blooms in late May and June. Mid- 
dle Temperate life zone. From southern Wyoming on the headwaters 
of the Platte to central Colorado and the Sangre de Christo range on 
the Atlantic slope only, a species of very limited extent. 
183 Astragalus Feensis Jones Cont. 8 20 (1898). Pods. about 3 
mm. wide, and high, minutely puberulent, with cross-section triangu- 
lar-cordate, with dorsal suture sulcate and intruded fully to the veniral 
as a white partition. Flowers unknown. Calyx tube about 4-5 mm. 
long, teeth shortly pubescent, triangular, much shorter than the tube. 
Bracts minute. Pedicels very short. Peduncles slender, about 7 cm. 
long and about as iong as the leaves or more. Leaves about 5 cm. 
long, many, with petioles fully as long as the rachis. Leaflets 7-8 
pairs, oval, 5-7 mm. long, rounded to notched, densely appressed- 
hairy. Old leaf-petioles persistent. Stems tufted, very short. Whole 
_ plant densely appressed-hairy. This was collected only by Fendler, 
No. 151. on gravelly hills at Santa Fe Nov M skito, May 28 1847. 
Lower Temperate life zone. 
184 Astragalus ensiformis Jones Cont. 7 658 (1895).P ods abcut 6 
mm. high, and 3 mm. wide when fresh, but much laterally flattened 
when dry, fresh walls 1 mm. thick and soft and a little sulcate on the 
ventral but not on the dorsal side, when dry both sutures are raised 
and thick making the reflexed pods appear vetch-like. Pods arched 
to one third circle, abruptly contracted but obtsue at both ends, the 
Stout mucro at tip an extension of the ventral suture, dorsal suture 
produced as a thin partition and reaching almost to the ventral, fresh 
= cross-section ee e adi filled by the seeds. Flowers like 
cles abou 
l erg 
‚dm. long, rather shorter than the leaves. Leaves 
stems, ab Qu oma SU ER pairs, grein 
pus Pow of A. cibarius. Pedicels short. Bracts ovate, about 3 mm. long.  — :
