1919] SCHNEIDER, NOTES ON AMERICAN WILLOWS. V 29 



River, Rockbridge County, Virginia. It also occurs in Fairfax County and 

 Elizabeth County (nearBuckroe), Virginia, and it is possible that the form 

 mentioned under var. venulosa from Norfolk County (Dismal Swamp) be- 

 longs to var. Wardii or that both varieties meet in the southeastern corner 

 of Virginia. 



The best way to distinguish var. Wardii is by the obtuse stipules, all the 

 other characters are apparently too unstable, but, of course, the extremes of 

 each variety seem to be distinct. Collectors should look for var. Wardii 

 in the southern part of Ohio, Indiana and Illinois as well as in different 

 parts of West Virginia, western Virginia, Tennessee, northern Alabama, 

 northern Missouri and Arkansas.
