The great botanical distinction between the wil- 

 low and poplar, compared with all other trees of 

 ordinary occurrence, has been mentioned above. 

 The discrimination of the particular kinds of wil-

 The larger kinds, natives of Great Britain, may be

 to each extremity. In the common willow, Salix

 The poplars are few in number, and are at once 

 told by the shape and colour of the leaves. Those 

 of the abele, or white poplar, are angularly toothed 

 or lobed, and covered upon the under-surface with a
