whole of the leafit seems covered by them, whilst in P. Filix-mas the 
upper end is always bare. The lower pair of leafits on each wing-, that 
is, the pair next to the principal or primary leaf-stalk, stand close to it, 
and parallel with it, pointing- upward and downward. The breadth of 
the leafits varies considerably in different plants, but when they are 
narrow and the wing-s distant, the whole has a remarkably light and 
elegant appearance.

( Aspidium irriguum, E. Bot. 2199, scarcely one-fourth so large as the pre¬ 
ceding, of which, nevertheless, some good Botanists have thought it a 
variety; and, indeed, after long cultivation, though raised originally 
from seed, it considerably approaches that species. In a wild state the 
fronds are of a more narrow lanceolate figure, and of a paler pellucid 
green; the main stalk occasionally scaly, but in general quite smooth, 
and exactly quadrangular, though the latter circumstance varies. Leafits 
shorter, and somewhat less linear than in F.foemina, deeply serrated, or 
partly pinnatifid, their segments sharply cut, without bristly points. 
About the margins of clear springs. Several places near Tunbridge. Mr.

(P. dilata'tum. Frond doubly winged: leaflets deeply wing-cleft: 
segments oblong, blunt, sharply cut, tipped with little spines: 
common stalks scaly: involucrum circular.

In moist rich soil three or four feet high, and trebly winged ; on dry rocks 
on banks about a foot high, the first pair of wings the largest, and the 
only pair that are triply divided. Bolt. Serratures ending in short awns. 
Woodw. Stem scaly all the way up. Lower leaves of the lower wings 
larger and longer than those opposite to them. First leaves from six to 
thirty inches high; rib destitute of leaf more than half its length; ge¬ 
neral figure of the leaf triangular, tapering upwards to a point. Second 
leaves of a triangular figure, tapering to the extremity. Bolt.
