364 FILICES. [Asplenium. 
Mackay Cat. 1825. On Ture Mountain (J. R. Kinahan) 
Cyb. 1866. Foot of Cromaglaun: Thos. Moore 1855. In 
dry rock-clefts near the Upper Lake, Killarney, 1896-1914, 
and sparingly in rock-clefts near Loo Bridge, Glenflesk, 
1907: R.W.S. 
This elegant form of Asplenium Adiantum-nigrum is, un- 
fortunately, like the Trichomanes, in much request by fern 
hunters and has been almost certainly exterminated in 
several of the localities given above ; for this reason a too 
exact description of any new locality in which this fern 
may be found is not advisable. It is probably, however, not 
so rare in the county as would appear from the few records 
given. It is a lover of rather dry clefts in rocks, rarely 
growing in exposed positions, and so readily escapes observa- 
tion. Although a well marked example of this variety looks 
very distinct, intermediate forms occur both in Kerry and 
elsewhere, and Dr. Moore has found that under cultivation 
even the extreme form reverts to the type; see also New- 
man’s British Ferns 1844, p. 260. 
This well-marked form occurs chiefly in the south and 
west of Ireland, it has been found also in the west of England. 
It is abundant in several districts in the Spanish peninsula. 
A. marinum Linn. Sea Spleenwort. 
Districts I. II. III. — V. VI. VII. VII. Ix. 
Native. In clefts, caves and rocky hollows by the sea, and 
on old walls near the coast. Rather common and some- 
times abundant around the coast, also found in one locality 
inland. Peren. July—October. 
Inland—VI. By the Upper Lake on the road between 
Killarney and Kenmare: Newman 1840 & 1844—=still in 
this locality, but sparingly, in 1914: R.W.S. 
Ascends to 325 feet above sea-level at Lamb’s Head, 
Darrynane, to about 400 feet in the slate quarries on Valencia 
Island (R.W.S.), and to 700-750 feet on the cliffs of the Great 
Blasket Island (Praeger & Stelfox). 
First record in 1756: Dr. Smith, Hist. of Kerry, p. 374, 
No. 21. “ On the rocks near Dingle, and many other places 
on this coast.” 
The inland locality for this fern given above is especially 
interesting as being the only one in Ireland where it grows 
quite removed from maritime influence. The few other 
inland localities known are situated either along tidal 
estuaries, as at Snowhill, Co. Kilkenny, or in the vicinity of
