Hymenophyllum.} FILICES. 359 
From sea-level near Lough Currane, &c., to 3,127 feet on 
the summit of Brandon (R. W.S.), and to 3,300 feet on the 
Reeks (Hart). 
First described as a British plant in 1830 under the name 
H. Wilsoni by Hooker in Brit. Flor. Ist Ed., p. 446, from 
specimens gathered by Mr. W. Wilson at Killarney. 
_ This is the more widely distributed of the two Filmy Ferns 
in Kerry, as, indeed, it appears to be throughout the British 
Isles. It is more partial to the mountains than H. tun- 
bridgense and usually ascends on them to a much greater 
height. In the lowlands, however, they not infrequently 
grow mixed together and both are especially abundant and 
luxuriant about the Killarney Lakes.

Native. In damp shady places amongst rocks, in hollows 
under or beside large boulders and along rocky mountain 
streams. Locally abundant as recent as 60 years ago, now 
very rare indeed. Peren. August—October. 
I. Near Kenmare : Cyb. 1866.—II. Near Lough Brin north 
of Blackwater bridge, Kenmare Bay (Rev. O. F. d’Arcy) 
Dub. Univer. Rev. 1886, p. 605. By the Lake at Waterville 
(Bab. in Herb.) Cyb. 1866 and ’98. Gathered by several 
collectors in various places along the south side of Lough 
Currane, circa 1875, but these stations have long been 
stripped.—III. Near Derriana Lake north-east of Water- 
ville: Cyb. 1866. Valencia, ‘“‘ perhaps introduced” *

Valencia, 1905 : Miss Delap. At Blackstones, Glouin [Glen] 
Caragh (Andrews) Newman 1844, p. 310.—IV. On the snuth 
side of Mount Brassel, Reeks, at about 500 feet, but exter- 
minated there recently : Hart 1882. Plants gathered on the 
Reeks were offered there for sale to Mr. Colgan in 1885 : 
* Bearing on the status of these Valencia localities, there occurs in 
Newman’s British Ferns 1844, p. 309, the following passage, ‘‘ Mr. Robson 
found it [Trichomanes] higher up the stream [Torc] . . . in such plenty as 
to procure a number of roots which he has planted abundantly, not only 
about Killarney, but about Glengarriff and in Valencia Island”’ ; it is quite 
possible, however, that the fern is both indigenous and planted in different 
localities in this island.
