history and distribution are matters of great interest. A careful exa¬ 
mination of the three localities noted above, viz., Waterford, Killarney, 
and Yalentia, have convinced me that the form called “ Andrewsii ” 
after its discoverer, to whom also is due the identification of this plant 
with radicans of Swartz, is the normal form of the plant; the form 
which occurs at Killarney, and by which the plant is best known, having 
been drawn up by moisture, by which the parenchymatous portions of 
the plants are developed at the expense of the fructification. The plants 
at Waterford fruit freely, and are scarcely distinguishable from An¬ 
drew sii, but under cultivation many of them pass into the ordinary 
Killarney form. 
Ilymenophyllum Tunbridgense. Tunbridge Filmy Fern. 
Clare : Monounta, Feakle, abundant on bare cliff, 500 feet high, 
J.R.K. Tipperary: Morgan’s Glen, E. H. Sargint, Esq., mixed with 
next, q. v. Kerry: Yalentia Island, rocks over Glenleavey woods, cliffs 
near slate quarries, sparingly; Killarney, abundant. Waterford: 
Glandine, sparingly; Portlaw; Curraghmore wood, abundant and fine, 
J.R.K. 
This species has been confounded with the next; thus the stations 
given by authors at Glencree and the Waterfall, county of Wicklow, refer 
to next. I have never seen authentic specimens of this species except 
from the south and west. 
Hymenopiiyllum unilaterale ( Wild). Wilson’s Filmy Fern. 
Tyrone : Gortin Gap, abundant among rocks, 1857, J. R. K. “ Tip¬ 
perary: Morgan’s Glen, E. H. Sargint, Esq.,” q. v. Kerry: Yalentia 
Island, near slate quarries, common. Killarney: very common, J. R. K. 
“Dublin: Kelly’s Glen, W. Andrews, Esq.” Wicklow: Waterfall, 
very abundant. Glencree : Greater Sugarloaf, scarce, J. R. K. 
This species is most commonly diffused in the east and north, but 
grows more luxuriantly at Killarney than anywhere else that I have 
seen it. 
The following Irish species have been recorded, and authentic spe¬ 
cimens of them have been shown to me, but I have never been fortunate 
enough to meet them myself:— 
Adiantum capillus- Veneris (Linn.). Maidenhair. 
“Leitrim: Glencar,” Right Hon. J. Wynne, vide “NaturalHistory 
Review,” page 69, vol. iv. Kerry: “Tralee, W. Andrews, Esq.,” 
q. v. “Galway: IJrrisbeg,” W. M'Calla. “Clare: Rallyvaughan.” 
Polystichum lonchitis {Linn.). Holly Fern. 
“Sligo: Benbulben,” q. v. “Kerry: Rrandon.” 
Hemestlieum Thelypteris {Linn. sp.). 
“Kerry: Killarney, Mucruss Demesne.” Professor R. W. Smith, 
M. D., showed me an extensive living series of this plant from this, 
Mackay’s original station, in 1856. “Mayo and Antrim.”
