McArdle — On the Hepaticce of the Dingle Peninsula. 291 



Here I found, for the fii'st time, Lejeunea Holtii, which was only 

 once found before in KiUamey. From here we collected on to Lispoll, 

 and got into Mr. Hickson's wood, which banks a dell where Fuchsia 

 Riccartoni assumes tree dimensions. Among the rarities gathered was 

 a proliferous form of Lejeunea serpylUfolia, with leaf margins covered 

 with buds and young plantlets, showing the asexual mode of repro- 

 duction in these curious plants. This is figured in the Irish Naturalist, 

 vol. iv., 1895, with others, from a paper read by me before the Dublin 

 Naturalists' Field Club, in March of same year. Other excursions 

 were made to Bumham Wood, Ventry, &c. 



In April, 1897, I was again in Dingle with Mr. F. "W. Moore. I 

 believe it was an Easter Sunday morning that we met John Kavan at 

 the village of Ballybrack, near the foot of Mount Brandon ; he is a 

 trusted guide, and a stranger without him would be in some danger on 

 Mount Brandon on account of steep precipices and fogs which fall 

 quickly. This was a beautiful clear day, and from the summit the 

 view was one to be remembered. 



During the last four years, the Eev. Canon Lett, of Loughbrick- 

 land, county Down, and myself, pushed our investigations of Hepaticae 

 into the most remote and unfrequented districts in the peninsula. 

 From the foot of the Cahirconree we followed the Derrymore river 

 thi'ough the glen to its source, under cliffs which rise to 2700 feet. 

 From here we pushed on to Emalough and Inch, where, amongst 

 other rarities, we found Cephalozia denudata ; then on to Lough- 

 anascaul, which is a truly wonderftd formation of barren rocks. The 

 best collecting ground is across the slopes to the ravine, through which 

 the water rushes to the lake ; it lies due east. "We followed it to the 

 summit, and found many rare Hepaticae, notably Dumortiera, which 

 grows there more plentifully than in any other station we know of. 

 The rare Metzgeria hamata and Radula Carringtoni (fertile) was found 

 gi'owing on larger hepatics on wet rocks. The latter was previously 

 only known to grow at KiUamey. From here we pushed on to the 

 bog, known as "Puck's Island," and followed the Eiver Owenalon- 

 drig up to Barnanaghea lough, and on to the summit, 2000 feet. From 

 this we could see across the Coumanare lakes to Brandon bay, and on 

 the Dingle side, Castlemain harbour, the Killarney Eeeks, and Dingle 

 bay — a panorama of scenery one seldom gets a chance of looking at, 

 and all splendid collecting ground, as we gathered Lejeunea Holtii, 

 and many other rarities. From here we pursued our investigations 

 across Ballysitteragh to Connor pass, and at the summit struck off to 

 the Coumanare lakes — a wonderful network of loughs of various
