94 DUBLIN NATUEAL HISTORY SOCIEXr. 



Lastrea montana {Vogler sp.). Mountain Fern. 



Tyrone: Gortin Gap, sparingly, 1857. Galway. Clare : Feakle, very 

 abundant. Kerry: Killarney, scarce. Waterford: Clonmel, scarce. 

 Dublin : Dodder Valley, local. Wicklow : Lough Breagh and Glenda- 

 lough, J. R K. 



This fern is very local, but, for the most part, abundant where it 

 occurs. It cannot, however, be called the common fern of any of the 

 districts recorded except Clare ; it is the inhabitant in that country of 

 wild mountain sides, near Lough Graney. The deciduous growth of its 

 fronds has, doubtless, caused it to be often overlooked. It appears to be 

 commonest in the west. 



Lophodium Fosnesecti {Lowe sp.). Bree's Pern. 



Tyrone: Omagh, common. Monaghan: common. Galway: very 

 common. Clare : abundant, but local. Tipperary : rare. Kerry : very 

 common. Kilkenny : Piltown, common. "Waterford : Curraghmore, 

 very common. Dublin : extremely rare. "Wicklow : Glendalough, very 

 abundant; Sugarloaf, rare, J. R. K. 



This well-marked species, as will be seen from the above list, is one 

 of the most commonly diJQPiised ferns in Ireland, being in fact a most 

 characteristic plant of the west and south. On the other hand, in Dublin, 

 and the counties more immediately adjacent thereto on the north-east, 

 it is extremely rare. I know of but two localities in which it occurs in 

 Dublin — Howth, and Glasavullawn, in the Dodder Valley. 



Lophodium muUiflorum {Roth sp.). Roth's Fern. 



Generally diffused and abundant. It is one of the characteristic ferns 

 of the east and north-east, especially in the bogs, replacing Bree's fern 

 of the west. 



Lophodium spinosum (Both sp.). "Withering's Fern. 



*' Monaghan: Dartrey,,Rev. Mr. Lovatt Darbey ; auct., I^ewman*s 

 British Ferns." Tipperary : bog drains, Annagh Inch, near Birr. Wa- 

 terford : Curraghmore, Portlaw, 1858, J. R. K. I believe I also got this 

 species near Cahirciveen, county of Kerry, 1856, J. R. K. 



This species is certainly not common in Ireland, In the stations at 

 Tipperary and Waterford it grows luxuriantly, but confined to a few 

 stations. 



Bryopteris affinis {Fischer sp.). Fischer's Fern. 



General, and generally diffused, and always distinct from the next. 

 It grows most luxuriantly, and in a greater state of development at Be- 

 ragh, county of Tyrone, than in any other locality in which I have met 

 with it.
