THE MALE FERN 
consists in its bearing bulbils, generally on the external side of the stipes, near its junetion with the 
tufted caudex. Probably in old plants the viviparous character will be more abundantly developed, 
5. dichotoma (№). This is a multifid variation of the normal Filir-mas, exact 
corresponding in its 
peculiarities with the variety mudtifida, already noticed, in having the apex of the frond and of all or 
the greater part of the pinnw two-cleft or many-cleft, the pinnæ ocensi 
nally depauporated. It is only 
sub-permanent, Tt differs from multifida &c., in the absence of the golden scales, and the other marks 
of the paleacea group. 
6. incisa (М). Аз already expla 
ned, this is a larger plant than the normal form, of which it is 
probably the full development, It is distinctly bipinnate; the pinnules elongate, narrowed upwards, 
and usually bearing sori nearly their whole length. It is a common and very ornamental plant, with 
am erect stately habit, A very large and handsome form of this variety, with the pinnules more 
distant, narrow, and eloi 
wi 
te than usual, as well as somewhat faleate, has been gathered in the Isle c 
ht, by Mr, A. б. More and the Rev. W. Н. Hawker 
7. erasa (W.. This, which is doubtless the Aspidium depastum of Schkuhr, is dist 
inguished by the 
irregularly laciniate form of the рішше and pinnules, giv 
& the appearance of having been nibbled by 
insects. It is occasionally multifid at the 
es of the frond and pinn, but not uniformly so. It is 
fertile and sub-permanent, 
8. deorso-lobata (М). A lar 
owing variation of the incisa group. The pinnules are oblong 
and obtuse, the basal ones with а narrow attachment ; the margins of the basal ones are more or less 
inciso-lobate, with the lobes serrated, and the lower posterior one much 
occurs in various lesser degrees in most of the comm 
states of this type. 
are more ог less inciso-serrate. This is the variety “spinosum ” of the earlier editions of Mx, F 
Analysis of British Ferns (under Aspidium), but is not at all spinose. It appears to be comm 
to be in fact one of the two Та 
y forms into which the species is commonly developed, the 
characteristics of the two being sometimes united in one plant. The Rev. W. A. Leighton appears to 
have first noticed the peculiar lobing ; his specimens 
athered twenty years since are from Bomere and 
desea. We have also seen 
Sutton in Shropshire, and from А) 
Callende 
peeimens from Ballyvaughan in Ireland, 
in Scotland, Bedale in Yorkshire, Black Park in Bucks, Maidstone and Cobham in Kent, 
Albury in Surrey, Epping in Essex, Lynn in Norfolk ; as well as from Jersey and Guernsey 
9. producta (М. This is а very striking variety, somewhat analogous to incisa, being like it a 
large growing plant, with fronds at least three feet long and ten inches broad, and also n 
mbling it 
the divided condition of the pinnules, which are however much more deeply divided. The frond is 
lanceolate ; the lowest pair of pinne two inches and a half long, triangular a 
the next are 
gular elo nearly two inehes across the bi 
more than four inches long, tria 
se, gradually 
per part of the frond, though narrower at the 
yg to a sharp elongated. point ; those in the w 
го also triangular elongate, the base being broadest, thi 
igh in the uppermost the sides become 
more nearly pa 
allel. "The pinnules throughout are elongated, deeply pinnatifid, and narrow upwards 
to the apex, their outline being that of a narrow cone or pyramid; this, together with the deep and 
conspicuous lobing, gives to the plant a very distinct appearance mules, which are 
cut down more than half way to the midrib, have an attachment so narrow as to resemble a mere 
winged petiole ; the rest, half way up the pinnas though adnate are attached by less than their whole 
width. "The lobes of the pinnules are obscurely serrated at the end. "The sori are confined to the upper 
1 
central than the basal portion of th 
third of the frond; and on the only frond we have seen have a manifest tendency to occupy rather the 
pinnules: that is, they are distant from the base on those pinnules 
which occupy the lower half of the fertile pinna. This variety was found by the Rev. W. A. Leighton, 
at Wrekin, in Shropshire 
10, triangularis (ML). This form belongs to the incisa group, but has something of the aspect of
