A broader-leaved form has long been distinguished by British 

 botanists under the name of S. Forbyana Smith (afterwards 

 reduced to a variety), having obovate-oblong leaf -blades more 

 shortly acuminate, with a flatter and more serrate margin, sooner 

 glabrous, than S. rubra ; darker and less pubescent catkins ; 

 styles usually shorter. This is more nearly allied to S. purpurea 

 and to its broad-leaved varieties. S. rubra was restricted to 

 forms with longer narrower leaves, often more pubescent beneath, 

 margins more revolute and crenate-serrate, more silky catkins, 

 styles longer, forms in fact more nearly allied to S. viminalis. 



Grenier made a somewhat similar division of this hybrid 

 into two main varieties, viz., var. purpureoides, which includes 

 S. Forbyana Sm., and is nearer S. purpurea ; and var. viminaloides, 

 which includes our S. rubra forms nearer to S. viminalis. Anders- 

 son adopted Grenier 's division. Either of these may be con- 

 venient for arranging collections, but no definite line can be 

 drawn between the two variations. 



As to S. Helix L., while Smith connected it with S. rubra, it 

 is quite uncertain what Linnaeus meant by it. 



This hybrid is recorded for numerous counties in England, 

 from Yorkshire and Westmorland southwards ; a valuable osier, 

 it is frequently planted in osier-beds, and elsewhere usually intro- 

 duced, as it certainly is in a few Scotch counties — Peebleshire, 

 Selkirkshire, Lanarkshire, Perthshire, and Dumbartonshire ; also 

 in Co. Leitrim and Sligo, Ireland. Central Europe — from France 

 and the North of Spain to Russia.
