Athyrium Filix-feemina, var. incisum. Very common and fine. 
A form of this is also found in Kelly’s Glen, with glandulose green 
stipes; also a crisped, curled subform, analogous to that of Polysti- 
chum angulare. 
shes me var. molle. Rare. Kelly’s Glen. A 
frond so named by Mr. Newman was gathered by me there. In Kil- 
lakee woods, rather abundant. ; 
Asplenium Adiantum-nigrum, Linn. Local. On walls. Ona clay- 
bank at Friarstown, near Bohemabreena. 
be marinum, Linn. Rare. Used to be abundant at Kil- 
liney, but the station is nearly destroyed by railway cutting. Howth, 
North side. I have found it also on Killiney Abbey. 
is Trichomanes, Linn. Rare and local. On conglomerate 
rocks at Tilsadin; sparingly on rocks overhanging Glenismaul; in 
Shane’s Glen, on walls, very abundant and fine; Miltown Bridge. 
- Amesium Ruta-muraria, Newm. Local, but notrare. Friarstown. 
Phyllitis Scolopendrium, Newm. Common in suitable localities, 
Kelly’s Glen. 
Notolepeum Ceterach, Newm. Very local and rare. Whitechurch, 
a very few plants, on walls; Belgard, do. do.; (Laram, on North 
side of Liffey, more abundant, W. H. Luscombe, Esq.) 
Botrychium Lunaria, Swartz. Local. Kilnasantan and _ bluffs 
along Kelly’s Glen, in patches. A fine subform, with deeply incised 
fronds, found here, growing in patches, distinct from the ordinary 
form. Plants from six to nine inches high, growing with the next, 
April, 1854. This fern was found previonsly in this neighbourhood, 
by Dr. J. Mackay, higher up the glen. 
Ophioglossum vulgatum, Linn. All along the bluffs of the Dodder 
Valley, very abundant; at Kilnasantan, with the last, April, 1854. 
This includes all the species of true ferns I have myself met with. 
The following are recorded by Mackay as occurring; but I have not 
been fortunate enough to meet with them. 
Hymenophyllum Wilsoni. Kelly’s Glen ; also found there by W. 
Andrews, Esq. 
a Tunbridgense. Same place, but doubtless an 
error of nomenclature, the two species having been formerly con- 
founded by observers. Thus both are recorded at Powerscourt 
Waterfall: I have searched carefully, and could only find H. Wil- 
soni. Nor do I know of any authentic specimen of H. Tunbridgense
