44'2 3'L SALIX CAPllEA. [CL. XXII. 



The second species, with which S, caprca might easily be 

 confounded, is S, grandrfolia Ser. In particular, it has a 

 great resemblance to the third variety. But the principal 

 character of S. grandifoUa consists in this, that the catkins 

 appear at the same time with the leaves, whilst, in S. acumi- 

 nata, they appear earlier : that the leaves are much larger, 

 often six inches long, and properly lanceolate, nearly quite 

 entire, — the stipulae large, pointed, and semi-cordate, — and 

 the honey-gland drawn out to a great length. S. stipularis 

 Sm., does not belong to this species, because its catkins ap- 

 pear much earlier. 



S. patula Ser., olecrfolia Vill., lias also some resemblance 

 to the small-leaved variety of S. caprca, but the catkins ap- 

 pear late, first in May, when tlie leaves come forth. The 

 other species are less liable to be confounded. 



The natural affinity of Willows to Poplars is obvious : the 

 distinction of genera lies in the flowers, which, in the case of 

 Willows, consist only of simple scales. But in Poplars, be- 

 side scales, there is also a funnel-shaped corolla, with eight 

 or more filaments. Both belong to the catkin-bearing trees, 

 or the Amentaceae ; (Anl. ii. 344.)
