PERNS. 
[Asplenium. 
Des. — Frond tripinnate, ovate or deltoid, 4 to 8 inches high, dark 
green, rigid, and erect. Rachis black, smooth, slightly winged, 
clothed with pinnae only on the upper half. Pinnae alternate, those 
only on the lower part twice pinnate, the lowermost the largest. 
Pinnules deeply cleft, tapering at their base, sharply serrated at and 
near the top. Sori linear at first, round at last, covering the whole 
under surface of the frond. 
a Fronds rigid, tripinnate only at the lower part. ( The common plant.) 
fi Fronds delicate, tripinnate throughout. ( Not [i of Smith.) 
Sir J. E. Smith, in conformity with the old authors, makes another variety, 
differing only from the common plant in having long fronds and distant pinnae ; 
hut I leave any one to say if it be anything more than a drawn up plant of the 
common species, found as it was, solitary, in a dark cave. 
Hab. — a.: Common through the United Kingdom, on walls, rocks, &c. I 
have habitats from the Orkney Islands, and from those in the English Channel, 
from the eastern as well as from the western counties, from Wales, Scotland, 
and Ireland. Dr. Murray writes me, “Not common in the north of Scotland.’’

from twenty to forty pairs, oblong, tapering gradually to a point, the 
lower ones sometimes drooping. Pinnules very numerous, oblong, 
rather blunt, pinnatifid, or inciso-serrate, the serratures minutely 
toothed, but not aristate, the lower pair close to and parallel with the 
rachis. Sori solitary, near the base of the lobes, at first linear -
