usually more or less mixed with mosses. Common and locally 
abundant, but very rare or absent in the extreme north.

southern portion where, however, it is very abundant and 
luxuriant.—VII. In several localities on the northern slopes 
of the Slieve Mish range, as in the Curraheen and Finglas 
glens, &c.: R.W.S. 
From sea-level, to about 1,500 feet on Priestsleap 
Mountain (Carroll), but seldom seen much above 1,000 feet 
where its place is taken by H. unilaterale. 
First record in 1804: Wade Rar. ‘‘ Amongst moss, on 
moist rocks to thesouth of Turc bridge, Killarney, and in the 
Glynn [Glen] Earl Kenmare’s park ’’—seen recently in both 
these stations: R.W.S. ‘“‘ Very common in the wooded 
mountains near Killarney and other mountains in Kerry: 
Mackay Rar. 1806. 
This beautiful little fern occurs in great luxuriance about 
the Killarney lakes as well as in many other localities in the 
south and west, sometimes quite concealing the surface of 
damp shady rocks with a dense mantle of semi-transparent 
overlapping fronds. With the following species, it is not 
infrequently sold to confiding tourists as the “‘ real Killarney 
Fern,” a title both of them deserve more than does the now 
rarely seen T'richomanes radicans.
