M2 34. SALIX CAPRiiA, [cL. XXII. 



The second species, with which *S'. caprea might easily be 

 confounded, is S* grandifolia 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 stipulge 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., ole^sfolia Vill., has also some resemblance 

 to the small-leaved variety of *S'. caprea, but the catkins ap- 

 pear late, first in May, when the 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.)
