 same locality, common, September 18, 1892, C. S. Sargent (small tree; sterile). 



According to Lackschewitz this species differs from S. daphnoides Villars : " ramulis 

 tenuioribus, flaccidis, amentis paullo minoribiis angustioribusque, squamis in 

 amentis 9 ad basin glanduloso-crenulatis, germinibus vix compressis, stylo longiore, 

 stipulis ovatis v. remiformibus (non semicordatis)," and from S. acutifolia Willdenow 

 " amentis approximatis, ramulis conferte assidentibus, squamis in floribus 9 glandu- 

 loso-crenulatis, foliis latioribus in acumen minus longum productis nee non forma 

 Btipularum (non lanceolatis longe acutatis)." 



There is a specimen of Wilson's from Hondo: Lake Towada, alt. 300-600 m., 

 October 5, 1914 (No. 7616; tree 16-20 m. tall; girth 1.8-2.4 m.; sterile) which has
