This fern has a somewhat prickly appearance to the leaves which gives the plant its English name. It is a species of base-rich rock outcrops and is restricted within Northern Ireland to some cliffs in the Lough Navar Forest area of Fermanagh, where it was discovered fairly recently.

All names: Polystichum lonchitis (L.) Roth; Aspidium lonchitis (L.) Sw.
