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- 

 foliiis except Parry 81 and A. Nelson 9648. See under H. stri- 

 gosus and H. decumbens. 



Wyoming: Rocky Mountains, Nuttall; Parry 81; Mount 

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



Montana: Lima, Rydberg 2706; Red Rock, Shear 5043. 



Colorado: 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. 



Wyoming: Leckie, Merrell & Wilcox 537, 585; Steamboat 

 Mountain, A. Nelson 7085; Laramie Hills 198; Bird's Eye, 

 Nelson 9559. 



Montana: Helena, Rydberg 2708. 



Idaho: Beaver Canon, Rydberg 2707. 



Utah: Alta, Jones i2io.\ 



30. Homalobus humilis Rydb. Macbride has transferred 

 this to Astragalus, under the name A. Carltonii, as there was an 

 older A. humilis Bieb. 



Utah: Bullion Creek, Rydberg & Carlton 7147; Delano Peak, 

 7219 and 7219a; Mt. Ellen, Jones 5670; Panguitch Lake, 601571 

 (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. 



f This Macbride refers to A. Carltonii Macbride, i. e. to H. humilis, but the 

 pod is that of II. divergens and //. tenuifolius.
