266 RYDBERG: NOTES ON FABACEAE—II 
A. divergens Blankenship. It would have been more logical 
to reduce it to a variety of A. serotinus. It is not more distinct 
from that species than A. strigosus or A. Palliseri. None of the 
specimens cited by Macbride and seen by me belong to H. tenui- 
folius except Parry 81 and A. Nelson 9648. See under H. stri- 
gosus and H. decumbens.

Leidy, Tweedy 259; Medicine Bow, A. Nelson 9648.

Cororapo: Lake City, Pease; Hall & Harbour 142, in part. 
29. HOMALOBUS DIVERGENS (Blankinship) Rydb. In habit 
the plant resembles the preceding, but the leaflets are much 
broader and shorter. I have not seen the type, but Blankinship’s 
illustration (except the pod) represents the plant I have in mind. 
In the original diagnosis the pod is described as stipitate and is 
so figured. In all the specimens I have seen it is sessile. 
Blankinship might have had a mixture containing pods of some 
other species, as for instance the alpine form of H. Bourgovii. 
Not having seen the type, it was not so strange that I, under 
these circumstances, redescribed the plant as H. camporum.* 
This is the name it would bear, if by chance Astragalus divergens 
should be different from our present conception.

30. HOMALOBUS HUMILIS Rydb. Macbride has transferred 
this to Astragalus, under the name A. Carltonii, as there was an 
older A. humilis Bieb. 
Urtan: Bullion Creek, Rydberg & Carlton 7147; Delano Peak, 
7219 and 72194; Mt. Ellen, Jones 5670; Panguitch Lake, 6015n 
(this with narrow leaflets). 
31. HOMALOBUS OBLONGIFOLIUS Rydb. Macbride regarded 
this as a variety of H. hylophilus. As far as I know the plant 
* Bull. Torrey Club 32: 666. 1906. 
} This Macbride refers to A. Carltonii Macbride, i. e. to H. humilis, but the 
pod is that of H. divergens and H. tenuifolius.
