Rydberg: Notes ox Fabaceae — II 271 



liselli but the leaflets are much narrower and pubescent on both 

 sides. Besides the type, the following specimens belong here. 



Southern California: Kenworthy, II . M. Hall 1182; San 

 Bernadino Mountains, Parish Brothers 1281. 



Lower California: Orcutt, in 1885; 856, in 1883. 



41. Homalobus conovirens Rydb. Astragalus Coltoni mo- 

 abensis M. E. Jones. This is also related to H. stenophyllus, 

 but the leaves and stem are densely grayish strigose, the stipe 

 much shorter, the corolla dark bluish purple. 



Utah : Western slope of La Sal Mountains, Rydberg & Garrett 

 S536, 8564; La Sal Mountains, Jones, in 1993. 



Colorado: Naturita, Payson 336. 



42. Homalobus Antiselli (A. Gray) Rydb. comb, now 

 Astragalus Antiselli A. Gray, Bot. Calif. 1 : 152. 1880. 



This species differs from the three preceding in the broader 

 leaflets, glabrous above and strigose beneath. A. Hasseanus 

 Sheld.* is without doubt the same. 



California : Santa Catalina Island , Kixford, in 1 9 1 4 ; Sulphur 

 Mountains, Abrams & McGregor 40; Santa Inez, Mrs. Curran, 

 in 1885; Ventura, Elmer 3616; Santa Barbara, S. F. P. [Peck- 

 ham ?]; Torrey Q2 bis; Buenaventura, Hasse, in 1888. 



43. Homalobus filipes (Torr.) Heller. This is very closely 

 related to //. stenophyllus and distinguished only by the strigose 

 pod and strigose stem and leaves. The two species have been 

 confused and may not be specifically distinct. 



Washington : Fort Okanogan, Pickering, in U. S. Exploring 

 Expedition; Grand Coulee, Griffiths & Cotton 440; Ritzville, 

 Sandberg & Leiberg i6j; Sprague, Sandberg & Leiberg, in 1893;

44. Homalobus inversus (M. E. Jones) Rydb. comb, no v. 

 Astragalus inversus M. E. Jones, Zoe. 4: 276. 1893. 



This is closely related to H. filipes, differing mostly in the 

 longer, more tapering and slightly curved pod.
