glabrous. Styles scarcely so long as the notched stigmas. (Sal. Wob., p. 37.) 
A native of Switzerland, where it forms an upright-growing tree, much re- 
sembling S. vitellina, both in twigs and foliage. Catkins accompanying the 
leaves, or appearing immediately after their expansion in May and June, 
and nearly 2in. long. According to Mr. Forbes, this species deserves cul- 
tivation for the sake of its twigs and rods, which are little, if at all, inferior 
to those of S. vitellina for tying, and for the finer sorts of wickerwork, 
baskets, &c. There are plants in the Goldworth Arboretum, and also at 
Woburn Abbey and Flitwick House.

cloven, longer than the style. (Smith E. F.) A native of Britain, and 
frequent on the banks of rivers in marshy ground ; flowering in April and 
May. A tall bushy-headed tree, sometimes found from 80 ft.to 90 ft. in 
height, with the branches set on obliquely, somewhat crossing each other, 
not continued in a straight line cutwards from the trunk; by which cha- 
racter, Sir J. E. Smith observes, it may readily be distinguished even in 
winter. The branches are round, very smooth, “and so brittle at the base, 
in spring, that with the slightest blow they start from the trunk.” Whence 
the name of crack willow; though, according to Sir J. E. Smith, this “is 
more or less the case with S. decfpiens, and several other willows, both 
native and exotic.” Many medical properties were formerly attributed to
