Native. Septal, Ericetal, &c. 1 am not prepared to ad-

 province of the Lakes, except my own recollection, un-

 rence of this very common English willow in either of the 

 two northerly provinces ; but the presumption seems so 

 strong for that of the North Highlands, at least, that I 

 reckon this latter province in the estimate. Possibly the 

 " S. aquatica" of the Shetland Flora may prove to be
