leys almost to the sources of those rivers.”^' Dr. Greville, who 
has obligingly supplied me with specimens, has since disco- 
vered it in woods near Forfar ; and Dr. Balfour, to whom I am 
also indebted for specimens, has supplied me with the following 
list of Scotch localities : — “ Woodcockdale wood, near Linlith- 
gow ; in woods at Castle Campbell, near Dollar ; in a wood 
at Carlochar glen ; head of Glen Isla ; in Campsie glen and 
Finglen, near Glasgow ; in woods near Corra Lin, Lanarkshire ; 
in woods near Dunfermline ; and in woods at Auchindenny, near 
Edinburgh.” 
This species has also been found in Ireland. Mr. Moore, of 
the Glasnevin Botanic Garden, says, I suppose this species is 
not unfrequent in the county Antrim, on the sides of mountain 
glens where the geological formation is similar to that at Wolf- 
hill, viz. lias mixed with hardened chalk, but of this I am not 
exactly sure : the only place where I have collected specimens 
was a deep mountain glen near Cushendall, called Glendoon : 
I took it for a variety of E. sylvaticum, not being then ac- 
quainted with the species ; but on comparing the specimens with 
those picked at Wolf-hill,” the residence of William Thompson, 
Esq., and the original Irish locality, I found them identical, 
and it strikes me forcibly that I have passed it over in several 
other glens.” 
I am not aware of its having hitherto been recorded as inha- 
biting England or Wales, but Mr. Woodward’s herbarium con- 
tains a fine specimen gathered by Dr. Forbes Young in a moist 
wood near Mere dough, by Manchester ; and I have no doubt 
that when the attention of botanists is once called to the sub- 
ject, it will be found abundantly in all the moist woods of our 
northern counties. 
This species is described by Willdenow, Decandolle, Yau- 
cher, Dietrich, and other authors, as E. umhrosujn, and by Sir 
William Hooker and Mr. Babington as E. Erummondii. It is 
well figured by Vaucherf in all its states ; the figure in ‘ Eng-
