DICECIA DIANDRIA. 213 



New-water-haugh plantation, where there is a barren 

 tree. Mouth of the Whiteadder, &c. April, May. 



A large tree with smooth branches, and alternate leaves, 

 which, when full grown, are about 5 inches long, and 1 

 broad in the middle, tapered at each end, and coarsely 

 serrated throughout. The barren tree is very rare, and, 

 if we are correct in our determination of it, the figure in 

 WITHERING is not good. Its catkins are 2 inches long, 

 cylindrical, yello\v, diandrous, the filaments not much 

 longer than the pointed, more or less villose, scales. 

 They stand on short leafy branchlets ; and these young 

 leaves are entire, from 1 to 2 inches in length, but not 

 otherwise different from the adult ones. Fertile catkins 

 rather longer, lax, with smooth lanceolate germens. 



This is " found the most profitable for cultivation of 

 any species of the genus, for the value of its timber as 

 well as bark, the rapidity of its growth, and the handsome 

 aspect of the tree." The bark contains more of the tan- 

 ning principle than any other tree in this country, except 

 the Oak; and if contradictory accounts have been given 

 of its value in tanning and in medicine, as a substitute 

 for the Cinchona, these are probably to be attributed to 

 the bark of different species having been indiscriminately 

 employed. 



The celebrated Willow near Lichfield, which goes by 

 the name of the Johnson Willow (not that it was planted 

 by the Doctor, but that his delight was to repose under 

 its shade), proves to be S. Russettiana. The magnitude of 

 this tree is truly surprising ; the trunk, at six feet above 

 the ground, measures 21 feet in girth, and extends 20 

 feet in height of that vast size before dividing into enor- 

 mous ramifications. The whole trunk, thus comprising 

 about 130 solid feet of timber, continues perfectly sound, 



and the very extensive head shews unimpaired vigour. 



Rev. S. DICKENSON, 1812. 



4. S. Helix, branches erect ; leaves partly opposite, oblong, 

 lanceolate, pointed, slightly serrated, very smooth, linear to- 

 wards the base ; stamen 1 ; style nearly as long as the linear di- 

 vided stigmas. Rose Willow. 



Hab. "Banks of rivulets. Sides of the Whiteadder between 

 its mouth and the bridge. April. 



" Branches upright, smooth and polished, of a pale yellow- 

 ish or purplish ash-colour, tough and pliable." A bushy 

 shrub, or tree, which withstands storms better than any 

 other.
