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. 



Colorado: 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. 



32. Homalobus paucijugus Rydb. This resembles H. 

 tenuifolius in habit and pod but differs in the few leaflets. As 

 there is an older Astragalus paucijugus Schrenk, Macbride re- 

 named my species A. Garrethi. 



33. Homalobus decurrens Rydb. This was also renamed 

 A. Rydbergii by Macbride, on account of A. decurrens Boiss. 



Colorado: Golden, Jones 528; Greene; Estes Park, Oster- 

 hout 2222; Lake Eldora, Clokey 3201; Jefferson Countv, 3808; 

 Larimer County, OsterhontA; 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. Palliseri, 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 

 2774; Empire, Tweedy 5642; without locality, Hall & Harbour
