By the sides of streams and on damp rocks. Common in the north 
of England and in Scotland; rare in the south. The var. Croweiina 
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
