and Knockagh, R. LI. P. Near Knockmore, Co. Fermanagh, W. H. P. 

 Island in Lough Erne, Co. Donegal, T. H. Corry. Redhall and Glenoe are 

 two well-known stations for this handsome variety, and at both it grows 

 abundantly and luxuriantly ; in the latter place we have measured fronds 

 H foot long by 9 inches broad. It is almost confined to Co. Antrim — 

 doubtless the limestone is the attraction there, but why is it so rare in other 

 limestone tracts? 



2. P. PBEGOPTERIS. Seech Fern. 



Damp rocks and banks. Not common. 



Ascends to over 2000 feet in the mountains. At 2400 feet on Slieve 

 Bingian. 



Antrim. — North branch of Glenarve river, Templeton, 1809. On Slievenanee, 

 and in Glendun, Rev. S. A. Brenan. Glenariff, W. H. P., R. LI. P., &c. 

 By waterfall on Inver river above Glenariff, and by the Carnlough and 

 Linford rivers, and on Trostan, R. LI. P. 



Down. — Two miles south of Slieve Croob, and on Slieve Bingian, Templeton 

 (and later in latter station, Rev. H. W. Lett and R. LI. P). Black 

 mountain, above Tollymore Park, W. Thompson ; (since observed there, 

 Rev. H. W. Lett, W.H.P. and R.L1.P.) Rostrevor, Rev. George 

 Robinson. On Slieve Donard and Slieve Commedagh, S. A. Stewart. 

 Luke's mountain, W.H.P. Sparingly near Craigauntlet above Holywood, 

 and on Slieve Bearnagh, Slieve-na-glough, and Thomas mountain, R.L1.P. 



Louth. — Carlingford mountain, Robt. Browne, 1801, and since by B.N.F.C., 

 Rev. H. W. Lett, W. H. P. and R. LLP. 



Armagh. — Frequent on rocks on N.E. slope of Slieve Gullion, Rev. H. W. 

 Lett. 



Derry. — Ness Glen, Templeton. By the Owenrigh river, near Banagher, 

 S. A. Stewart. Near Dungiven, B.N.F.C., 1872. 



Donegal Lough Eske, Mackay. Near Killybegs, A. G. More. Glenalla, 



Carradoan, Angterlinn, Croghanmore, Poisoned Glen, Banagher 

 mountain, Glenveigh, Alt mountain near Ardara, near Lough Finn, 

 Milford, woods by coast between Slieve-a-tooey and Magheragh, and at 

 2000 feet on Slieve Snacht West, H. C. Hart. Crockaughrim, Charles 

 Moore. 



Tyrone.— Strabane Glen, W. H. P. 



Fermanagh. — Near Brookeborough, Rev. S. A. Brenan. 



3. P. DRYOPTERIS. Oak Fern. 



Shady places on mountains. Extremely rare. 



Antrim. — North side of Knocklayd, Cybele Hibernica. Since a single plant 

 of this fern was discovered by Dr. Moore in the above locality nearly 

 half a century ago, it has not been observed in the North of Ireland, and 

 we very much doubt if it can now be reckoned among our local ferns.
