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 hyaliine 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 W^yoming 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 Pulsiferae 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, ioiclined to be a little s ilcate 

 ventrally ?long the middle, red stijipled 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 

 circle and filling the whole banner above; blrde 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 

 cm. 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 bnse and scarcely at all flattened, at tip very flat 

 and with the deltoid beak about 3 mm. long and with declined tip,
