2. argutum (M.). This variety has a b r o a d lanceolate frond, with
distinct pinnules as in the typal plant, from which it differs in Üie
form of the pinnules, which are narrowed and elongated, boooming
linear terminating in an acute spiny point, and having long spines
to the marginal teeth and a prominent auricle. I t w'as gathered in
some part of Buokinghamshire, by Mr. J. Lloyd. [Plate X V II B.
Folio ed. t. X B.]
3 . cristatum (M.). This variety, which has only recently boon discovered,
has the pinnæ pinnate for about half their length, while the
apical portion is pinnatifld with oblong acute lobes, rounded in front
as in lohatum, these lobes becoming more and more confluent as they
approach the apex which is slightly dilated and crispy as in the cristate
varieties of other Ferns, but in a less degree. The upper pinnæ
are confluent, and the apex of the frond is aouminate. The pinnules
are oblong, acute, with a wedge-shaped base and a small anterior
auricle. I t was found at Barnstaple, by Mr. II. F. Dempster.
4 . crassum (M. ). This variety has the pinnules remarkably thick;
they are also short, broad, overlapping, and doubly serrate. I t was
found near Basingstoke, by Mr. F. Y. Brocas.
5. multifidum (Woll.). This has tho apex of the frond divided into
a spreading tuft of branches. Mr. Wollaston has obtained it from
Suffolk. Some plants of this character are inconstant.
