UNDESCRIBED WILLOWS OF ‘THE SECTION CORDATAE 
CARLETON R. BALL 
(WITH ONE FIGURE) 
While this paper is a continuation of the series which has 
appeared under the title Notes on North American willows, this 
general title is dropped now in favor of a specific one for each 
contribution. This seems desirable because it will permit a clear 
indication of the contents of each paper in the title thereof. These 
papers have resulted chiefly from studies made in preparing the 
treatment of the genus Salix for different floras and manuals of 
botany.”
