RYDBERG: NOTES ON FABACEAE—II 267 
is confined to Colorado. Macbride cites two specimens from 
Wyoming, Nelson 869 and Payson 2068. The former, as repre- 
sented in the Columbia University Herbarium is typical H. hylo- 
philus, having glabrous pod and broad leaflets. The other 
number I have not seen. 
CoLorADOo: Cerro Summit, Baker 409; Nederlands, Clokey 
3284; Leadville, Jones, Teller, C. S. Sheldon 108; Marshall Pass 
and Leadville, Jones; Pinkham Creek, Goodding 1472, Delta, 
N. F. T. Nelson 181; without locality, Parry, in 1864. 
. HoMALOBUS PAUCIJUGUS Rydb. This resembles dH. 
pectielias< in habit and pod but differs in the few leaflets. As 
there is an older Astragalus paucijugus Schrenk, Macbride re- 
named my species A. Garrett. 
33. HOMALOBUS DECURRENS Rydb. This was also renamed 
A. Rydbergii by Macbride, on account of A. decurrens Boiss. 
CoLorapo: Golden, Jones 528; Greene; Estes Park, Oster- 
hout 2222; Lake Eldora, Clokey 3201; Jefferson County, 3808; 
Larimer County, Osterhout A; Stove Prairie and Como, Crandall; 
Gray Back, Rydberg & Vreeland 5960; Tolland, Johnston & 
Hedgecock 664; without locality, Hall & Harbour 142, in part; 
Central City, Sccvell. 
34. HOMALOBUS MICROCARPUS Rydb. This was reduced by 
Macbride to a synonym of A. decumbens. There would have 
been more reason for reducing it to, or for making it a variety of, 
H. divergens, since the general habit, the form of the leaflets 
and the shape of the pod approach that species, but the whole 
plant is greener, more luxuriant and more erect. One specimen, 
Watson 287 from the Uintah Mountains, Utah, may belong 
here. It has the small pod and the flowers of H. microcarpus 
but is taller, with very long peduncles, 10-14 cm. long, longer 
leaves, up to 15 cm. long, and more numerous leaflets, the pod 
is hairy with short black hairs. Macbride erroneously referred 
the specimen to Astragalus serotinus var. Pallisert, which has 
glabrous pods. 
COLORADO: east of Rabbit-Ear Range and on the forks of 
Poudre River and Big South, Crandall; Como, Crandall & Cowen 
131; North Park, C. F. Baker; Steamboat Springs, Osterhout
