66 TRANSACTIONS OF THE [jAN. 'Zl^ 



Phaseolus Wrightii, Gray. Apparently this species. Baker'& 



Butte (231). 

 Hoffmanseggia drepanocarpa, Gray. Fort Verde (197). 

 Prosopis j'liliflora, DO. Fort Verde (353). 

 Cassia bauhinioides. Gray. Fort Verde (229).

Geum striatum, Ait. Baker's Butte (59). 



Fragaria Virginiafia, Duschesne. Mogollon Mts. (71). 



Potentilla fruticosa, L. Mogollon Mts. (243). 



Pote}itilla'T/iurberi,Gvay. Mogollon Mts. (50). This is the 

 very silky form of the species, with large flowers, the same as 

 Dr. Rothrock's No. 399 from Mt. Graham, and Dr. Rusby's 

 No. 128, also from the Mogollons. Dr. Mearns collected other 

 specimens, the exact locality uncertain, which are smoother 

 and smaller-flowered, much more nearly resembling the orig- 

 inals of Thurber and Henry. This silky form from the higher 

 mountains may, perhaps, best be separated as a variety.
