plant was found by me abundantly, 1856, growing in clefts in the rock, 

 and in dry stations generally ; the plants generally single. 



Asplenium marinum (Linn.). Sea-side Spleenwort. 



General along sea-coast. Valentia Island, inland, at an elevation of 

 500 feet above sea, J. R. K., 1856. 



As common in the east as the west, in favourable localities. I never 

 went anywhere that I did not find it on the cliffs. 



Asplenium trichomanes {Idnn.). Maiden-hair Spleenwort. 

 General. 



A local species, generally diffused ; it is naturally a denizen of the 

 clefts of bare rocks. 



Amesium ruta mura/ria (Linn. sp.). Wall Rue. 



General. 



Universally distributed, though, from the peculiarity of its growth, 

 local ; it attains its highest development on rocks, and also on shady 

 walls, in some cases covering these to the total exclusion of every other 

 kind of vegetation. 



Scolopendriwn vulgare {Linn. sp.). Hart's Tongue. 



General. 



This species occurs all over the island, but most irregularly; in 

 some stations in immense profusion ; in others, seemingly as favourable 

 to its growth, one or two stunted plants alone will occur. It is a cha- 

 racteristic eastern species, as in the coimty of Dublin.

 rare, (very local). Wicklow: Glendalough, Enniskerry. Queen's 

 County, J. K K. 



A local fern, much more abundant in the west than in the east ; it 

 is very characteristic of the former districts. 



Trichomanes radicans {Swartz). Killamey Pern. 

 "Limerick: Cumailte Mountains, on authority of specimens in 

 Glasnevin Gardens." Kerry : Valentia Island (this locality first noted 

 by Miss H. Blackburn e), apparently introduced; Killamey, Tore moun- 

 tain, very abundant, 1856, J. R. K. Waterford: '* Glouin Caragh,"
