THE WILLOWS OF OHIO. 279 



The ripe capsules of Salix amygdaloides are narrowly long-conic 

 on long pedicels, contrasting with the short pedicelled capsules 

 of Salix nigra and giving the aments a very different appearani 



S. amygdaloides is characteristically a swamp plant though 

 it is not absent from river banks. In Ohio it- range is over the 

 northern and western parts of the state. I olumbus is near its 

 southern limit in central Ohio; further east it does not extend 



Far south while further west 1 suspect it may even reach the 

 river. It is a north-western species of which Ohio is near the 

 'astern limit. 



While remaining for the most part recognizable in the west, 

 Salix amygdaloides loses the glaucescence of the under surface 

 f the leaf while the upper surface brightens till it is almost like 



'ix lucida. The shape of the leaves also changes and becomes 

 shorter and broader. Southwestward it grades into the varieties 

 of S. nigra which occupy the region. About St. Louis there is 

 a great complex of the amygdalenae in which pure forms of the 

 three constituent species are uncommon and there are all sorts 

 of interconnecting variations. In Ohio we have only two species 

 and intermediates are rare though several have been 

 collected. 



LUCIDAE. 



Trees or shrubs, branches shining; leaves often very long 

 acuminate, broadly lanceolate to ovate, thick, glossy, strongly 

 glandular; catkins leafy peduncled, thick and dense, scales cadu-

short, stigmas thick.
