SCALY SPLEENWORT. 
299 
Clare. — Mr. W. Thompson says it is common on the lime- 
stone in this county ; and I observed it in many localities, par- 
ticularly in the vicinity of Castle-Connel. 
Cork. — I observed it most abundantly in many parts of this 
county : Ceterach^ Adiantum-nigrum^ Ruta~muraria, Tricho- 
manes and Scolopendrium half cover many of the walls about 
Cork and Fermoy. 
Down. — From Mr. W. Thompson I learn that it occurs at 
Bryansford. 
Fermanagh. — Mr. W. Thompson informs me that the Hon. J. 
L. Cole observed it at Florence-court in this county. 
Galway. — Mr. W. Thompson observes it is common on the 
limestone in this county. In many parts of the county I ob- 
served it in the greatest possible luxuriance. In and about the 
little town of Oughterard I was much struck by its beautiful ap- 
pearance, intermixed with Cotyledon Umbilicus^ there also gi- 
gantic, nearly covering many of the humble dwellings. 
Kerry. — I observed it upon rocks and walls in many places 
round Killarney. 
Kilkenny. — Mr. Mackay observes that it is abundant at the 
marble- quarries at Kilkenny. 
Limerick. — I saw it in many places near the town of Limerick. 
Waterford. — I saw Ceterach in many parts of this county : 
it occurs here and there on nearly all the walls between Clon- 
mel and Waterford. 
Wicklow. — I observed this fern on several of the old build- 
ings at Glendalough. 
The Scaly Spleenwort is found in all the middle and southern 
countries of Europe, but I believe it has not yet been ob- 
served in Lapland, Norway, Sweden, or the North of Russia : 
it is common in the North of Africa, in the Canary and Cape de 
Verd Islands. In Madeira and Tenerilfe there is a plant of 
much larger size than ours, and of more beautiful appearance ; 
I cannot take on myself to say whether the two forms are iden- 
tical as species. 
Very intelligible figures of this fern are given in Schkuhr,*
