rushing through a narrow clay-slate gorge well stored with Asplenium 
Trichomanes, Dryopteris affinis, and Phyllitis Scolopendrium. During 
this entire valley the botanist will find himself in a paradise, especially 
of ferns, as in or about it are found more than two-thirds of the species 
recorded as Irish ; not to speak of other rarities, such as Listera cor- 
data, Habenaria viridis, H. albida, and other plants rare in the West 
of Ireland. Of the Musci and Fungi I will not speak; but if any 
cryptogamist wishes a treat, let him search these glens, and he will 
not repent his labour. 
Lastrea montana, Newm. Local. Abundant in the glen near 
Middleton Brook, where I first met it in June, 1854. Glenismaul, 
more sparingly. 
Lophodium Feenisecti, Newm. Very rare. A few weak plants in 
the Lot-Brook Glen, at the foot of a cascade; also in a glen in the 
Feather-bed, very weak and straggling. Hill of Howth, North side, 
very rare. I cannot account for the rarity of this fern, so abundant in 
the neighbouring countries, and so general throughout Ireland. 
BS mulliflorum, Newm. Very common, especially on the 
exposed mountain-sides and in the shady glens. All the plants have 
spines on the portion of the stipes next the ground. 
Variety “nanum.” Very common. Not always growing in the 
most exposed situations. Kelly’s Glen. 
N.B. Further study of this group will doubtless discover other of 
the named forms. These are all I can be certain about. 
Dryopteris affinis, Newm. Very common, frequenting low grounds. 
Very distinct; earlier in vernation and more robust than the next, 
often growing more than five feet high. Friarstown and Dodder Val- 
ley. 
3 Borrerit, Newm. Very common, frequenting for the 
most part the higher grounds. About a month later than the last in 
its vernation. asily distinguished from that species by its golden 
yellow colour. Dodder Valley. 
Athyrium Filix-foemina, Roth. Very common. The following 
varieties are found. I cannot convince myself of their distinctness ; 
or, rather, | know several other forms as distinct and not intermediate, 
particularly the two glandulose ones recorded below. 
= var. convexum (?). What I take to be this form is 
common on the hills, varying much in its size and cutting. A most 
beautiful form, with red stipes, covered over with glands, is found in 
Kelly’s Glen. It appears distinct.
