By the sides of streams and on damp rocks. Common in the north 

 of England and in Scotland; rare in the south. The var. Crowetina 

 is said to grow in Norfolk, but whether it be really wild there I have 

 no means of knowing. The neighbourhood of Richmond, Yorkshire, 

 and the Breadalbane Mountains, Perthshire, are the two places from 

 whence the greatest number of forms has been reported, very probably 

 because these localities have been carefully explored by botanists who 

 have paid special attention to willows. 



England, Scotland, Ireland. Shrub. Late Spring, and often again in 



the end of Summer. 



A polymorphous species, sometimes only a foot or two high, some- 

 times 6 to 12 feet. The branches are fuscous or dull purple, shining 

 and glabrous, sometimes pubescent when young. The leaves, when 

 mature, are more or less rigid, glabrous, and shining, with a somewhat 

 greasy lustre above, with the veins scarcely at all impressed, more or 

 less glaucous beneath ; when young they are more or less membranous, 

 and somewhat hairy, especially beneath ; their size varies from 1 to 2 or 

 even 3 inches in length, and their breadth, and even their shape, is 

 extremely variable ; the margin is generally more or less undulated 

 or serrate, but sometimes entire. The stipules are rarely present, 

 and always small, lanceolate or ovate, half-cordate or half-sagittate. 

 The catkins are later in appearing than in most of the willows; the 

 male about 1 inch long; the female often 2 inches or more, and 

 frequently becoming lax in fruit. The catkin-scales are black at the
