THE MALE FERN. 191 
variety spinosum of the earlier editions of Mr. Francis's Analysis of 
British Ferns, but is not at all spinose. It appears to be common, 
and to be in fact one of the two larger forms into which the species 
is commonly developed, the characteristics of the two being some- 
times united in one plant. The Rev. W. A. Leighton appears to 
have first noticed the peculiar lobing; his specimens gathered 
twenty years since are from Bomere and Sutton in Shropshire, 
and from Anglesea. We have also seen specimens from—Penryn, 
Cornwall; Cobham Park, and Maidstone, Kent; Mayford, Sutton 
Park, St. Martha’s Hill, and Bagshot, Surrey; Epping, Essex ; 
Lynn, Norfolk; Black Park, Bucks. ; Salisbury, Wilts. ; Dayles- 
ford, Worcestershire; Matlock, Derbyshire; Leeming Lane, Bedale, 
Yorkshire; Ambleside, Westmoreland; Castle Malgwyn, Pem- 
brokeshire; Ruthin, Denbighshire; Callender and Kinnoul Hill, 
Perthshire; Glen Gilp and Cairndow, Argyleshire; Arran ; Tin- 
nahinch, Wicklow; Ballyvaughan, Clare; Killarney, Kerry; 
Athenry, Galway; and from Jersey and Guernsey. 
5. producta (M.). This is a 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 resembling it 
in 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 acuminate ; the next 
are more than four inches long, triangular elongate, being nearly 
two inches across the base, gradually tapering to a sharp elongated 
point; those in the upper part of the frond, though narrower than 
those below, are also triangular elongate, the base being broadest, 
though in the uppermost the sides become more nearly parallel. 
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. The basal 
pinnules, 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 pinne, 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
