S iHIS is the first of the interesting genus, Asplenium or Spleenwort. 
The fronds appear in April, and remain evergreen. 
The roots are strong, and penetrate deeply into the crevices of rocks; the rhizomes are tufted 
and often matted together in large masses. The fronds are from two to four inches long, and have 
very much the appearance of grass, but terminate in forks. The seed is produced in elongated 
clusters on the under surface of the frond, near the forked ends. 
pbitei 
Very rare. Occurs in the following localities in Caernarvonshire and Denbighshire:—namely, 
Carnedd Llewellyn, Llyn y Cwm, Pass of Llanberris, Moel Lechog, Bettws y Coed, near Pont y Pair, 
and at Llan Dethyla. 
None. 
Mint 
Being a tender fern, this requires much care in cultivation: it succeeds well in pots in a cold 
and shaded frame, requiring plentiful moisture, which should he well drained off.

pretty little fern must be fa mili ar to everybody, as it occurs abundantly on the walls of 
§|J[|f most old buildings. 
The fronds, which are evergreen, appear about May or June. 
The roots are black and wiry; the rhizomes are tufted, and are much matted together. The 
stem is long, and stronger than the frond, the length of the whole being in general three or four 
inches. The frond is triangular and bi-pinnate. The seed is produced in diamond shaped clusters, 
which cover the under surface of the pinnules. 
Common on rocks and old walls. 
§mtm. 
The only variety of any importance is one which many botanists regard as a distinct species, 
under the name of A. Germanicum; it resembles the normal Buta-muraria, but is simply pinnate, 
instead of being bi-pinnate. It is very rare; and has been found near Llanrwst, and on Moel 
Lechog, in Caernarvonshire. 
fylkxt 
This fern does not thrive if removed from its native walls or rocks; but if it be desired to culti¬ 
vate, it should be planted amongst broken bricks and old mortar, and be but sparingly supplied with 
moisture. 
* The specimens of A. Septentrionale given in this work were procured by the author in Norway, and are precisely similar to those 
found in "Wales.
