more normal. The fronds are very broad and about two feet high. 
This form, which somewhat approaches irregulare, was found at 
Tunbridge Wells by Mrs. Delves. [Plate LIX B.] 
— laciniatum minus (M.). A dwarf form, six to eight inches high, 
irregular in development like laciniatum itself, the parts deeply 
laciniate-toothed. It has been found at Ilfracombe, in Devon- 
shire, and communicated by Mr. C. Jackson. 
- laciniatum dissectum (M.). A very beautiful dwarf form, mode- 
rately irregular in the outline of the frond, and considerably so in the 
outline of the pinn®; the pinnules are, however, rather less abbre- 
viated, and rather more regularly and distinctly laciniate-toothed, the 
teeth being long narrow and prominent. This very elegant form, 
which is toothed like odontomanes (12), was found in Newton Dale, 
near Whitby, Yorkshire, by Mr. Clapham. 
36, exile (M.). A dwarfish slender form, with narrow irregular 
long-pointed pinne, and unequal-sized narrow or linear-oblong 
pinnules, which are deeply pinnatifid, the lobes here and there 
enlarged, producing ramose pinnules; the lobes have short bluntish 
teeth. The fronds are much more slender than in dissectum or dif- 
Jissum, and less depauperate than in laciniatum. It was found by 
Mr. Stansfield, of Todmorden; and a somewhat similar form, also 
found by Mr. Stansfield, comes from Antrim, in Ireland. 
97. erosum (Woll.). This form is of medium size, the fronds 
lanceolate, and nearly normal in outline, the pinn® being of the 
usual size. The pinnules, where most normal, are blunt, oblong, 
pinnatifid, and decurrent, the lobes unequal with short bluntish 
teeth ; they are, however, frequently variously depauperated, so as to 
become unequal in size, and the lobes being sometimes dispropor- 
tionately developed, the fronds have an irregularly laeiniated appear- 
ance; the pinnules are sometimes even bifid or multifid. It was 
found in Kent, near Tunbridge Wells, by Mr. Wollaston; and 
similar forms have been found in—Devonshire: Marwood, Rev. F. 
Mules ; Kerry : on Cahir Conree, near Tralee, Dr. Allchin. Another 
plant, somewhat more regular and normal-looking, with a tendency 
to dilatation at the points of the pinnules, was gathered by Dr. 
Allehin in the Isle of Man. The following, also, is closely allied 
to this variety, but is a plant of smaller growth :—
