ASPLENIACE^, 
part whereof is of an overworne whitish colour.” ^ Modern 
botanists do not seem to have met with this fern in mining dis- 
tricts, but the hint is worth reviving. 
Besides the English and Welch localities given below, it 
is said by Jacob, in his ‘ Planta 0 Favershamienses,’ to grow on 
the north side of Bocton church, in Kent ; but I quite agree 
with the authors of the ‘Botanist’s Guide’ in supposing that 
Mr. Jacob mistook Ruta~muraria for the present plant. 
Caernarvonshire. — Ray records that this fern was found by 
Mr. Llwyd on the summit of Carnedd Llewelyn.f Mr. Wilson 
has found it near Llyn-y-cwn, and Mr. Babington on rocks near 
the pass of Llanberis : I had the good fortune to discover it in 
profusion on a loose stone wall, about a mile from Llanrwst, on the 
Conway road ; the locality is on the left hand, looking towards 
Conway, and exactly opposite a small farm-yard. Several bo- 
tanists have visited the place subsequently, and taken it away in 
such quantities as nearly to destroy the habitat, — so nearly in- 
deed that others have been unable to discover a trace of its 
former existence. I deeply regret the prevalence of this exter- 
minating spirit, for it tends to deprive the true botanist of one 
of his greatest pleasures, — that of visiting rare plants in their 
native localities. It however affords me some satisfaction to 
know that the plant has been lately observed by Mr. Wilson 
on the same wall, two hundred yards nearer Conway, and that 
it grows in many other spots in the neighbourhood. 
Cumberland. — Mr. Heysham informs me that in 1837 and 
1838 he found this fern on Honister crags, and on crags in the 
vicinity of Scaw Fell. Hutchinson gives Patterdale and Kes- 
wick as localities. Turner and Dillwyn, on the authority of 
Mr. Wood, say it has been found in a ravine of the Screes, near 
Wastwater, about 600 feet in perpendicular height ; and Mr. 
Francis informs us that it occurs sparingly on rocks between the 
vale of Newlands and Borrowdale. 
Denbighshire. — It is recorded by Ray that Dr. Richardson 
found it on old walls at Llan Dethyla, about a mile from Llanrwst
