from this locality : those shown me as such are all H. Wilsoni, which 
T find in its distribution in Ireland is the more northern fern of 
the two, H. Tunbridgense replacing it in the South. All our critical 
practical botanists with whom I have conversed on this subject hold 
the same opinion. 
Osmunda regalis, Linn. Formerly found in Kelly’s Glen. - The 
station is now drained, which perhaps accounts for its not being found 
there now. 
The fern-allies I have not studied so well ; therefore my list is more 
meagre. [soetes lacustris and Pilularia globulifera are wanting, owing 
to the absence of suitable localities for them. The Lycopodiums 
are well represented, the only species wanting being L. alpinum, an 
alpine species, and L. inundatum, found, | believe, in the Co. Gal- 
way, but I have never seen Irish specimens. In the Equisetums the 
following are wanting :— E. Mackaii, a northern species; E. umbro- 
sum, also a northern species, though I believe I have met with it in 
Dublin; and E. Moorei, a new species, lately discovered in Wick- 
low, and described by Mr. Newman. 
Equisetum arvense, Linn. Too common; a troublesome weed. 
Kelly’s Glen. 
“= hyemale, Linn. Rather rare. Near Whitechurch. 
a limosum, Linn. Local. Common in swamps along 
Grand Canal. 
“ palustre, Linn. Common. Firhouse; Kelly’s Glen. 
The following varieties all occur :—nudum, rare ; alpinum (?); poly- 
stachion, very rare, Kelly’s Glen. 
ee variegatum, Weber & Mohr. (Portmarknock Strand, 
North side. I have been shown fresh specimens). 
7" sylvaticum, Linn. Very fine and abundant. Kelly’s 
Glen, and Three-rock Mountains. 
45 Telmateia, Ehrh. Very fine and abundant. Kelly’s 
Glen, and the entire valley of the Dodder. 
Lycopodium selaginoides, Linn. Rare. (Howth, North side. 
Plants shown me). 
ss clavatum, Linn. Rare. Cruagh Mountains, Feather- 
bed, and Kelly’s Glen. 
sj Selago, Linn. Common on high bogs. Middleton 
Brook and Kelly’s Glen, and over mountains generally.
