igig] SCHNEIDER— AMERICAN WILLOWS 343 



Arboretum which was brought by Professor /. G. Jack probably 

 from the St. Lawrence region in Ontario. It is extremely Hke the 

 female specimen of Bissell from Glastonbury, Connecticut, and 

 both agree well with the specimens cited from Maine and New 

 Brunswick. In BisseWs plant the stigmas are rather long and 

 narrow, resembling somewhat those of the western 5. fliiviatilis 

 but without a trace of a style. The leaves too of both plants 

 are not very different in their shape, but var. Wheeleri has a 

 coarser silky pubescence of longer hairs. Rowlee stated that 

 "the silvery vesture of this shrub is much like that of S. argophylla 

 of the Pacific Coast." As I have explained under this species, 

 Rowlee did not interpret it correctly. 



At present I refer to var. Wheeleri the following specimens, and 

 I hope collectors will pay attention to this plant at the localities 

 given.
