224 THE BRITISH FERNS. 
fronds are four or five inches long, nearly or quite an inch broad, 
lance-shaped with the lower segments shorter, but terminating 
abruptly and without the long diminishing base which is usual in 
the species: thus only about a single pair of lobes are semi- 
rotund, the rest being ovate and then oblong. The sterile fronds 
only are known. It was found by Mr. Stansfield in the Vale of 
Todmorden. It has somewhat the outline and aspect of Lomaria 
alpina. 
18. latifrons (M.). The sterile fronds of this large-growing form 
resemble those of Lomaria lanceolata ; they are about six inches long, 
and an inch and a half broad, lanceolate, narrowing rapidly to the 
base, the segments crowded, the longer ones broad-linear, somewhat 
falcate, and having a short acute point. The fronds are mode- 
rately thick in texture. It has been found by Mr. Stansfield, of 
Todmorden, at Eastwood, Pennant-Clough, and elsewhere, and by 
Mr. Nowell and Mr. Patman, in Mytholm Valley. 
19. majus (M.). In this, of which fragments only have reached 
us, the segments are two inches long, dilated at the base, and 
tapered towards the acute apex. It is an unusually large form ; 
and was found by Mr. Elworthy, near Nettlecombe, Somersetshire. 
20. abruptum (M.). This form appears permanent. The fronds 
are developed in a normal manner, to about half the usual length, 
at which point the rachis stops short, the apex consisting of one 
or two segments set on endwise. The plant was found about 
Todmorden, and communicated by Mr. Stansfield. 
21. subserratum (M.). This is a very elegant and a permanent 
form. The fronds are narrowish, six inches to a foot in length, 
the shorter about three-fourths of an inch, and the latter an inch 
and a quarter broad, sometimes almost linear, in outline, the base 
being often scarcely narrowed, but sometimes more or less tapered 
below; the fronds are usually curved in a lateral direction, and the 
acute segments are remarkably curved forwards in a falcate manner, 
so much so as to overlie each other; the anterior margin of these 
segments is entire, while the posterior margin is notched with con- 
Spieuous shallow rounded lobes or crenatures. The fertile fronds 
have precisely the same deorsely-crenate character. This variety was 
found near Malton, Yorkshire, by Mr. C. Monkman, and has been
