168 THE BRITISH FERNS. 
slender elegant form resemble irregulare (32) in outline, being 
sinuately-lobed, or irregularly contracted or laciniate ; they are also 
marginate almost close to the edge, and in most parts dentate; the 
base is truncate or subcordate, the apex attenuate or bifid. It was 
found at Oldstead in Yorkshire by Mr. C. Monkman. 
63. marginato-lobatum (M.). A very handsome variety growing 
from nine to twelve inches or upwards in height, the fronds about 
an inch wide, laciniate toothed along the margins, and dividing in à 
multifid manner at the apex into several (5-6) lobes, which are 
toothed like the frond and narrow off to a point. It has been raised 
from spores both by Mr. Elworthy and Mr. Wollaston. A dwarf 
form resembling this, with narrow marginate fronds forking above 
the middle, each branch divided at the apex into a tuft of dilated 
scarcely erispy segments, has been sent by Mr. C. Jackson. 
64. marginato-cristatum (M.). A beautiful variety raised by Mr. 
Clapham from spores of submarginato-multifidum (76). The best 
form of this has fronds six to eight inches long exclusive of the 
` stipites, and of the usual marginate character in the lower part, 
while the apex is divided into a large flabellate crispy tuft of lacini- 
ate segments three or four inches in breadth. In a second form, the 
fronds are more irregular and unequally marginate below, much 
narrowed upwards, and dividing into an irregular often one-sided tuft 
of segments. A third form (all these raised at one time) is smaller, 
narrower, with a less branched apical tuft, and more resembling 
marginato-lobatum (63). 
65. marginatum tenue (M.). A very interesting dwarf form three 
to six inches high, the fronds from one-fourth to hàlf an inch wide, 
distinetly marginate, and laciniate dentate, sometimes irregularly so 
at the margins, occasionally cornute, or with the apex dilated, some- 
times proliferous. It has been raised by Mr. S. Appleby of Don- 
caster,* and by Mr. W. Nixon. 
66. vivo-marginatum (Claph.). An odd-looking dwarf variety 
raised from submarginato-multifidum (76). The fronds are two to 
* Mr. Appleby states that his seedlings were raised from a narrow elegant form of 
submarginatum. Among the seedlings a considerable number, upwards of forty, 
were found to be dwarf, slender, and very prominently marginate; these are sup- 
posed to have originated from the spores immediately developed on the marginate
