122 Astragalus terminalis Watson Proc. Am. Acad. 17 370 (1882). 
Pods erect and appressed. about 4 mm. wide and 3 mm. high, some- 
what aıched, broadly sulcate and with septum partly intruded; tip de- 
clined a little but nearly in line with the ventral suture, about deltoid, 
flattened, ending abruptly in-a subulate long mucro. Flowers purple 
and about 1.2 to 1.5 cm. long, nearly sessile but rather slender-pedi- 
celed in fruit. Banner oblong, arched to erect beyond calyx tips, with 
with sides reflexed 1 mm. wide in the middle, and about 7-8 mm. long. 
Wings oblong, 2-3 mm. longer than keel. Keel arched a little, short, 
purple, sharply rounded toa little more than erect, the erect part about 
as long as base and 3 mm. high. Calyx about 3 mm. long, the nigres- 
cent teeth very short and wide. Fruiting pedicels 3-4 min. long. The 
bracts ovate to subulate, hyaline, 1-2 mm. long. Pedunclles subter- 
minal and about as long as stems, strict, 1-2 dm. long, the floral rachis 
half as long. Leaves 5-15 cm. long, but root leaves shorter, with ob- 
ovate folded leaflets, and petiole nearly half the whole, Upper leaves 
with shorter petiole, the leaflets linear-oblong to oblong-ovate and 
-12mm. long. Leaflets 5-10 pairs, obtuse to retuse. distant, short- 
petiolulate, ashy below, rather thick. Stipules small, triangular and 
wide, about 4mm. long, Stems tufted, spreading, rather zigzag, a 
foot long or less, slender, with the two upper internodes 2-5 cm. long, 
the rest short, from a woody root. Headwaters of the Snake river in 
the vicinity of St. Anthony and Spencer Idahoto Yellowstone Park 
and over on the headwaters of the Gallatin river on sagebrush plains. 
It has the general appearance of the broad-leaved form of A. arrectus 
but the pod is strictly sessile and thicker walled, while the peculiar 
pubescence puts it in this group. Middle Temperate life zone. 
Astragalus terminalis var. reventoides (Jones Cont. 7 661 1895 as 
sqecies). Flowers ochroleucous. Pods about 12 mm. long, almost 
truncate at both ends, about 6 mm. wide and4 mm. high, with parti- 
tion intruded one third the way across. Leaflets oval to elliptical and 
hoary, inclined to be notched, otherwise as in the type. On the head- 
waters of the Gallatin river Montana on sagebrush plains. Lima and 
Grasshopper Creek. A poor variety. 
123 Astragalus Oreganus Nutt. in T. & G. Fl. 1335 (1838) A. 
ventorum Gray. Pods horizontal, lanceolate-oblong, with triangular 
beak which is decidedly declined and flattish. Flowers ochroleucous. 
Banner ovate, a little longer than wings. Wings 2 mm. longer than 
keel, and 2 mm. wide. Keel straight and with tip rounded and erect. 
Calyx inserted on the lower corner, a little wider below: tube about 5 
mm. long; teeth subulate and about 2 mm. long. Pedicels very short, 
bracts longer than pedicels. Peduncles shorter than the leaves, sub- 
terminal. about 7 cm. long. Leaves 7-12 cm. long, of 6-8 pairs of oval 
to obcordate leaflets which are thick, hoary on both sides and less than 
2.5cm.long. Stipules large. Stem hardly half a foot long, simple, 
erect, zigzag slender and from slender underground rootstocks, with 
few internodes which are rarely 2.5 cm. long. Pubescence ashy and ra- 
ther long. In the upper Snake river valley [daho and Wind river re- 
gion Wyoming on sagebrush plains. These two species are but little 
known and may not be distinct. 
Astragalus Canadensis Tourn in L. 757. (I take up this name in 
preference to Carolinianus which has only priority by position, and 
shonld not displace Tournefort's name on a technicality, in addition 
the latter is only a local variation of the other widespread species). 
Pods oblong, about 1.5 cm. long, little inflated, about 5 mm. wide and 
high, a little obcompressed, rarely noticeably sulcate, densely ap- 
pressed-spicate, smooth, with short mucro. Flowers yellowish- or 
greenish-white, very many, densely spicate, nearly sessile. Banner 
rather fleshy, arched far back, seemingly triangular because of the 
sides reflexed most at tip, nearly round, 5-8 mm. long. The groove | 
V-shaped except at base. Wings linear, slightly wider at the blunt — 
tip, ascending, about 2 mm. wide and 2 mm. longer than keel. Keel —
