218 DICECIA TRIANDRIA. 



From the remarks of Dr HOOKER, it would appear, that he 

 is inclined to consider this a variety of the preceding, but 

 the shrub we intend (and our specimen was named by Mr 

 WINCH), is altogether different, and more nearly related 

 to S, caprea, though very distinct from it. It is a small 

 tree or shrub, with lanceolate leaves 3 inches long, fully 

 one broad near the base, which, when the leaf has attain- 

 ed maturity, is rounded. The fertile catkins are small, 

 numerous, greyish, and silky ; the stigmas long and deep- 

 ly divided, elevated on a style rather shorter than them- 

 selves. 



18. S. alba, leaves elliptic-lanceolate, pointed, serrated, silky 

 on both sides, the lowest serratures glandular ; stamens hairy ; 

 gernien smooth, almost sessile ; stigmas deeply cloven ; scales 

 rounded. Common White Willow, 



Hal. Woods frequent. May. 



A large tree with a coarse rugged bark, and a copious fo- 

 liage of a beautiful grey silvery appearance, which must 

 have made it familiar to the most inattentive observers. 

 The properties of the bark and wood are similar, but per- 

 haps inferior to those of S. Russelliana ; and the two trees 

 have much the same general appearance. We have not 

 observed a fertile tree in this neighbourhood.

Mr NEILL saw at Deerness, in Orkney, very strong ropes, 

 calculated for different purposes in husbandry, made of 

 the shoots of this plant.
