SALIX. 371 
Salix acutifolia Willd. Alien. Found by James Ward in 
1831 at Broadhams near Wensley, a single bush only, which is 
now eradicated. More recently it has been met with by Mr. 
Mudd in Airyholme wood, and in two or three places by the 
Leven side near Great Ayton, but only in very small quantity 
in each station. 
Salix purpurea L. including S. He/ix. British type. Native. 
Area 9 8765.32. Range 0-250. Common by the stream- 
sides in the western dales, and occurring also more sparingly 
about the streams and damp woods in various parts of the low 
country. It ascends in Teesdale to Holwick, in Wensleydale 
to Hawes, and is sometimes planted in osieries. 
Salix rubra Huds. English type. Native. Areag87.5.2. 
Range 0-100. Banks of Barton Beck near Croft, of the Tees at 
Yarm, of the Swale at Richmond and in many places lower 
down, of the Yore at Tanfield, and of Codbeck at Thirsk ; also 
in Carlton Carr, and sometimes planted in osieries. 
Salix viminalis L. British type. Native. Area general. 
Range 0-250. One of the commonest species of the stream- 
sides of the low country, but less frequent in the western dales 
than Salix purpurea and Salix phylicifolia. Commonly planted 
in osieries. Grown in gardens up to 350 yards. 
Salix Smithiana Willd. English type. Native. Area 
general. Range o-300. Common throughout the lower zone 
about stream-sides and in hedge-rows and damp woods, ascending 
to the lower part of Widdale. Salix ferruginea and Salix rugosa 
are both frequent, but the genuine Salix acuminata (Salix 
dasyclados Wimmer) I have not seen from within our limits. 
Dr. Anderssen suggests that the plant from the neighbourhood 
of Richmond given in Leefe’s Salictum as No. 39, is Salix 
Sertngeana Gaud. 
Salix cinerea L. British type. Native. Area general. 
Range 0-450. Common by stream-sides, and in hedge-rows and 
damp woods, ascending to the falls of the Cover at the foot of 
Sept. 1892,
