50 ferns. [Asplenium. 
high, dull green. Leaf-stalk green, except at the very base. Pinnae 
confined to the upper half, from three to five or six in number, 
placed alternately, for the most part distinctly three-cleft. Pinnules 
ovate in small fronds, wedge-shaped in the larger ; their tips 
rounded and crenate, or unequally notched. Barren leaves broader 
and shorter. Sori dark brown, finally confluent, and covering the 
whole under surface. Indusium uneven at the margin. 
Sit. — On walls, ruins, rocks, and other similar situations. 
Hab. — Very generally distributed over the United Kingdom, though there are 
a few districts where it is scarcely found. I believe Berwickshire is one of these, 
nor is it by any means plentiful in Norfolk or Suffolk. 
Geo. — Most parts of Europe ; and from New York to Carolina, in America.

Des. — Rootstock very thickly tufted, black, with stout fibres. Leaf 
6 to 9 inches high, pinnate, irregularly oblong, obtuse. Leaf-stalk 
winged all the way down, black, shining, smooth, without pinnae at 
the lower part, above bearing from ten to twenty on each side, mostly 
alternate, obtuse, about an inch long in the middle of the frond, 
running at the base into the wing of the stalk, therefore slightly 
decurrent ; the upper side of each generally auricled, the lower side 
proportion ably truncated. Sori large, transverse, at first linear, then 
oblong, but never confluent. Indusium white, or of a pale brown. 
Sit. — Upon maritime rocks, or in caves by the sea-side, and in one or two 
inland situations.

Hulme Stone Quarry (otherwise called Winwick Stone Delph), near Warrington, 
where Bolton gathered it (??. Bolt. Fil. loc. cit.), Mr. W. Wilson. In this place 
Mr. Shaw, of Bollington, many years ago found a curious variety, with a much 
more divided frond than is usual, and which remains with him distinct in culture.
