culis subscapiformibus. — Near Richfield, Utah, at 5,900 feet, in loose 

 a§hy soil, Lester F. Ward, in Powell's Expedition. Apparently a 

 form of Nattall's species, but more condensed as well as hoary, and 

 witli somewhat the aspect of Oxytropis. The specimens supply mature 

 fruit, which is wanting in Nuttall's specimens. The legume is one-celled, 

 with little or uo introflexion or thickening of the dorsal suture ; while 

 externally the ventral suture has a very salient ridge and a shallow and 

 broad groove each side of it, somewhat in the manner of A. bisulcafus.

 berry. — On the frontiers of Utah and Arizona, Prof. Newberry. 

 Cafion east nf Glen wood, Sevier Co., Utah, at 7,000 feet, Lester F. 

 Ward, in Powell's Expedition, 1875. Having now the fruit, it is clear 

 that Newberry's plant, in flower only, is not the same as Phaca pyg- 

 mcea, Nutt., which should retain the name of A. Chamceleuce, while this 

 may take that of the original discoverer.
