remarkable, since many situations, especially in Cornwall, De- 
von, Somerset, Dorset and Wilts, seem peculiarly adapted to the 
growth of such a fern. I have given a list of the counties in 
which I have ascertained its presence, together with a few 
localities. 
Anglesea. — I have seen specimens from this county, but do 
not know the locality. 
Brecknockshire, — Mr. Ralfs has found it in woods near Bre- 
con, and at Trecastle ; Mr. Lees at Pont Henryd and Capel 
Colboen ; and Mr. Westcombe near Ystrad Felltree. 
Caernarvonshire. — I have observed it near Bangor; at 
Bhaidr-y-Wenol ; in the pass of Llanberis; at Cwm Idwell &c. 
Cheshire. — Mr. Wilson has observed it of very large size 
about two miles south of Warrington. 
Cardiganshire. — I have noticed it at Ponterwyd, and 
throughout the Devil’s bridge district. 
Cumberland. — Mr. Watson informs me he has observed it at 
Lodore, near Keswick ; Mr. Heysham near Honister crags, and 
in the village of Grange in Borrowdale ; Mr. Binder at Cal- 
der bridge, Ponsonby screes, Wasdale &c. ; and Mr. Winch 
gives Ashness gill, Scale force, and Gillsland, as localities. 
Denbighshire. — I observed it scattered over a rock on the 
left hand by the road-side just leaving Llangollen for the Capel 
Curig road ; the plants were small and discoloured, and the 
leaves convolute. 
Derbyshire. — In the ‘ Botanist’s Guide ’ the rocks about 
Pleasley forges, and Chinley hill near Chapel-le-Frith, are re- 
corded as localities. 
Durham. — Mr. Watson gives me this county as a habitat, on 
the authority of Mr. R. B. Bowman ; and Mr. Winch found it 
in Scots’ wood and Walbottle denes. 
Flintshire. — I have a memorandum that it has been found in 
this county near the town of St. Asaph. 
Glamorganshire. — Mr. Dillwyn has found it about Pont 
Nedd Vechn, and Mr. Lees at the waterfalls of Scwd-y-Gladis 
and Cilhepste ; and I once received specimens from the vici-
