T h i s new multifid variety of the Male Fern, although not so
dwarf as the Aspidium pumilum, (figure 15, vol. vi, of my
“ N a tu ra l History of British and Exotic F e rn s,” ) is nevertheless
of dwarf compact habit, and an interesting addition to our hardy
Ferns.
I t was found in Borrodale, Cumberland, by Mr. II. D.
Harrison.
The pinnæ are opposite below and sub-opposite above, dis-
tant, and from an inch and a ha lf to two inches in length,
their apices being branched and tasseled. The pinnules are
opposite.
The midrib very scaly.
Sori usually one on each pinnule, and in the larger and
broader pinnules two, the whole forming a single line close to
th e midvein.
Length of frond from twelve to eighteen inches.
F o r a frond of this beautiful and rare F e rn I am indebted
to Mr. Clowes, of Windermere.
The illustration is from Mr. Clowes’ frond.
