32. Astragalus miser Dougl. in Hook. Bor, Am. 1 153 (1834). A 
microcystis Gray, A. debilis Walp., A. amphidoxus Blankenship. Tra- 
gacantha Kuntze. Pods about 6-8 mm. long, nearly globose rarely 
oval, mostly very obtuse but apiculate, a little oblique and with ven- 
tral suture about straight, conspicuously inflated, ashy with soft 
spreading hairs, apparently minutely stipitate but the stipe not longer 
than thick, with very thin and wrinkling walls. Flowers about 5 mm, 
long, pinkish or white, 6-10. Banner oval, about 4 mm. long, abruptly 
erect at end of calyx, rather hooded, and deeply notched, with many 
twin veins of purple coming from near the base, the sides only slightly 
reflexed, about 1 mm. longer than wings. Wings half-oval, rounded at 
tip about 1 mm. longer than keel, white, appearing very oblique. Keel 
blade deltoid wholly, except for a short and narrow base, about 
2 mm. high, very obtuse. Calyx tube almost hemispherical, acutish at 
base, about 1 mm. long, the subulate teeth as long. Pedicels about 1 | 
mm. long, half as long as the lanceolate and ciliate hyaline bracts. 
Peduncles 1-3 cm. long, and the rachis nearly as long. Racemes loose 
5-12 flowered. Leaves 3-5 cm. long, with petiole rarely as long as 
lowest leaflets. Leaflets mostly obtuse, 4-6 pairs elliptical, rarely 
some are oval. Stipules narrowly triangular, about 5 mm. long. Inter- 
nodes 1-2 cm. long. Whole plant even to pods and calyx softly ashy 
with rather short and wavy white hairs partly appressed. Base of ~- 
stems decidedly woody. Along sandy bottoms from the eastern base 
of the Rockies to central Wyoming and northwestward through Mon- 
tana to the eastern part of the Columbia Basin proper as far as Ft. 
Colville and northward into British America. Middle Temperate life 
zone. A. miser x pauciflorus is a hybrid form and about intermediate 
between the two species, 
33. Astragalus Pulsiferze Gray Proc. Am. Acad. 10 69 (1874). A. 
Suksdorfii Howell. Pods oblately half-round, about 1 cm. long and 
nearly as wide and high, with ventral suture about straight in the mid- 
dle and then abruptly arched up at both ends, at base into a corner 
where it is sessile at right angles to the suture, and at tip into a 
flat and sharp upcurved deltoid beak 1-2 mm. long, translucent and tis- - 
sue-like and wrinkled, greatly inflated, inclined to be a little sulcate 
ventrally elong the middle, red stippled all over or green; cross section 
a little obcompressed, oval to oblate-oval, seed-bearing only in the 
middle. Flowers white, with waterlined banner a little shaded with 
purple, the banner about 3 mm. long, round, bent abruptly to about 
110 degrees just beyond tube, with sides reflexed 1 mm. wide at base 
only and blade becoming rather fiddle-shaped; groove almost a half 
eirele and filling the whole banner above; blade about 2 mm. longer 
than wings. Wings oblong, arched 30 degrees, 2 mm. wide, obtuse 
and with oblique tip, the right hand one incurved over keel and the 
other flaring, but the tips of both connivent over keel tip, fully 2 mm. 
longer than keel. Keel as in A. miser. Calyx about hemispherical, the 
tube hardly 2 mm. long, cleft deeper above, a little oblique at base, the 
subulate teeth lax, curved and as long to twice as long as tube. Ped- 
icels filiform, 1-2 mm. long, about as long as the subulate bracts. Ped- 
uncles and leaf rachis filiform and very short. Stems stout for the 
plant, about 2 mm, thick. Root woody and thick at crown. Pubescence 
of whole plant white-shaggy with long and spreading rather kinked, soft 
hairs. Growing in poor gravelly soil from Chat and Plumas Co, Cali- 
fornia nearly to the British line. Middle Temperate life zone, 
34. Astragalus diurnus Watson Proc. Am. Acad. 21 450 (1886). 
Pods obliquely ovate, or oblately half-ovate, about 2 cm. long and 1 
em. high, somewhat laterally flattened, with the ventral suture con- 
= vex a little at tip and base and concave in the middle or straight, 
nearly square at the base and scarcely at all flattened, at tip very flat
