GREEN SPLEENWORT.

dusty road which passed over it, seemed in no degree to increase 
the chance of success : yet on that bridge, facing the road-way 
and covered with dust, was the identical plant I sought — small 
indeed, but the species not to be mistaken.* 
Yorkshire. — Mr. Tatham, who informs me it is very common 
on the limestone cliffs above the town of Settle, has kindly sup- 
plied me with specimens. It has also been found near Halifax, 
Ais-la-beck, Richmond, Gordale, Gilla-leys wood, and other lo- 
calities too numerous to mention. 
In the Highlands of Scotland Asplenium viride is a fern of 
common occurrence. I should not call it an abundant fern, but 
it is almost impossible to wander amongst the mountains with- 
out frequently noticing it : a few counties are given below. 
Argyleshire.—I observed it in several localities. 
Dumbartonshire. — Mr. Gourlie has found it on Ben Voirlich. 
Lanarkshire. — I observed it growing by the Falls of Clyde ; 
and Dr. Balfour, Mr. Gourlie, and other Scotch botanists appear 
to be well acquainted with this station. 
Nairnshire. — Mr. Stables informs me that it is of common 
occurrence in congenial situations in this county. 
Perthshire. Mr. Gourlie and several other botanists have 
found it on Ben Lawers. 
Rosshire.— The Rev. G. Gordon has observed it in Rosshire. 
Sutherlandshire. — Mr. Watson has observed it in this 
county. 
In Ireland this fern appears to be much less common than in 
Scotland or the North of England. 
Cork.— Dr. Taylor has found it near Bandon in this county. 
Donegal. — Mr. W. Thompson informs me it was found by 
Mr. E. Murphy near Lough Eask. 
Kerry. — -Mr. Mackay and several other botanists give Turk 
mountain, by the Lakes of Killarney, as a locality. 
Sligo. — ■ Mr. W. Thompson and several other botanists have 
found it on Ben Bulben. 
Asplenium viride is found in all the countries of Europe, but 
I have not heard of its occurrence beyond the limits of that 
continent.
