be distinguished by its sharp fine serration contrasted with the 

 distant blunt and often coarse teeth of the pussy willow. The 

 habits of the two are sufheientiy dil to put aside all confu- 



sion when the plants arc seen together. From S. sericea it can 

 generally be distinguished by the absence of the silvery white 

 pub e on the under surface. The shape of the leaves is i 



different, in most cases in thi Les the leaf is widest near the 



middle; in this it is widest below the middle. Salix cordata also 

 lacks the peculiar leaf habit i ea. The flowers come 



very early from small pussies. As they mature the carpellate 

 aments come to be supported by largi es and much of the 



wool of the puss; E from the fruiting rachis. The anthers 



just before the elongati 'aments are almost as red as 



those of Salix sericea. The capsules are green and glabrous, 

 the stigmas frequently red. 



Solid cordata angustata hnders. includes the narrow leaved 

 forms of the species. In Ohio most plants have leaves wider 

 than those of the typical angustata but decidedly narrower than 

 the typical specific form. It is therefore difficult to distinguish 

 two forms in our area and since the leaf variation may be con- 

 sidered as accidental and without significance it is perhaps hardly 

 advisable to separate them. 



Salix cordata is abundant all over the state. Its usual 

 habitat is along ns while the other - with a similar 



habit and leaf are typically swamp plan; This is not to say 

 that the presenl grows in swamps nor that S. seri 



and S. discolor nevi v along river banks -for they do- but 



that they attain their b( pment in the habitats given 



and are usually found
