In the Bots de Gouerdere this grows intermixed with H. salebrosum, 
from which it is distinguished at sight by its leaves being paler and 
more silky, with longer more fleruose points and very faintly toothed 
margins ; but the most important character is the dioicous inflorescence. 
It is a very abundant species in the neighbourhood of York and Castle- 
Howard, but is rarely fertile : it never grows on trees. H. salebrosum 
I have seen in England only on trees in woods near Kirkham Abbey, 
in the vale of the Yorkshire Derwent.
