Astragalus adsurgens all. Astrag. 10, t. 31 (1800); Astragalus larmanni Pall. (*%), 
Nutt. & authors, not Jacq. Lately the name .f. larmanni Jacq.,' has been adopted 
for our American plant... Although there is nothing in the original description that 
really disagrees with our plant, yet the plate accompanying it shows that Jacquin’s 
A. laxmanni was of a different habit. The stem is very slender and decumbent, the 
leaflets narrower and smaller, the heads, or rather spikes, much longer and narrower. 
The pods seem to be like those of ut. adsurgens, but are more.truncate at the apex and 
have the style abruptly turned dorsally, making a right angle with the pod. In 
A, adsurgens the pod acuminates into a nearly central style, which issomewhat twisted 
and curved dorsally, but does not make a right angle. In the Columbia College 
Herbarium there is a specimen of 4. larmanni collected by A. Regel in Turkestan, 
which perfectly agrees with the figure in Hortus Vindobonensis. The flowers of this, 
although of about the length of those of 4. adsurgens, are much narrower, the calyx 
less than one-half the length of the claws of the petals, or with the teeth about two- 
thirds their length, while in 4. adsurgens the calyx with the teeth nearly equals the 
claws. 
Common in the region. Some specimens trom Hot Springs have a more decumbent 
stem and brighter blue tlowers. Hot Springs, altitude 1,100 m., June 8; Hermosa, 
altitude 1,050 m., June 22; Custer, altitude 1,700 m., July 15 (No. 617). 
Astragalus hypoglottis L. Mant. ii, 274 (1771). 
Not uncommon among the foothills: Hot Springs, altitude 1,100 m., June 14; Her- 
mosa, altitude 1,050 m., June 22 (No. 618). 
Astragalus drummondii Dougl.; Hook. Fl. Bor. Amer. i, 153 (1834), 
Hills near Hot Springs, altitude 1,100 m., June 18 (No, 619). . 
Astragalus racemosus Pursh, Fl. ii, 740 (1814). 
The corolla is ochroleucous rather than white, and the angles of the pods are 
blunter than in Nebraska specimens collected in 1891. Near Fall River Falls, alti- 
tude 1,000 m., June 17 (No. 620). 
Astragalus gracilis Nutt. Gen. ii, 100 (1818). 
Hot Springs, altitnde 1,100 m., June 15 (No. 573). 
Astragalus microlobus Gray, Proc. Amer. Acad. vi, 208 (1864). 
Hot Springs, altitude 1,100 m., June 15 (No. 621). 
Astragalus aboriginum Richards. Bot. App. 746 (1823). 
The fruit is membranaceous, long-stipitate, strictly 1-celled, but the dorsal suture 
a little inflexed, straight, the ventral one curved, It was collected in fruit only, 
north of Deadwood, altitude 1,500 m., July 5 (No. 622). 
Astragalus aboriginum glabriusculus (Ilook.); Phaca glabriuscula Hook, FI, 
Bor. Amer. i, 144 (1830). 
This has generally been regarded as a distinet species, but even Hooker says, in 
the original description, that it may be a variety of the preceding. The only dif- 
ference I can find is that the plant is smoother and the pod a little more curved. 
The flowers are ochrolencous, the keel tipped with purple. Custer, altitude 1,700 m., 
June 1; Rochford, altitude 1,700 m., July 12; Limestone District, altitude 2,000 m., 
July 26 (No, 623). 
Astragalus alpinus L. Sp. Pl. ii, 760 (1753). 
Hort. Vind. iii, 22 (1776). 
2There is a species from Japan, much larger but with the same pod characters, in 
the National Herbarinm. This was identified by Bunge, the well-known authority 
on Old World Astragali, as 4. adsurgens, but is evidently distinct. It differs in the 
style, and in its more slender, less distinetly striate stem, its looser head's on peduncles 
which are neither strict nor longer than the leaves. Notwithstanding Bunge’s deter- 
mination the plant can not be sl, adsurgens, this name belonging to our species, as is 
plainly shown by the original plates.
