THE BROAD PRICKLY-TOOTHED BUCKLER FERN. 235 
plant found at Elter Water, in Westmoreland, that the foregoing 
description has been drawn up. Miss S. Beever has communicated 
the same variety from Torver, near Conistone, where it was collected 
by Mr. T. Ecclestone; this latter plant is rather larger and more 
divided, and has prettily concave pinne, and strongly convex pin- 
nules, and the plant is also somewhat glandular, which is hardly, if 
at all, the case with that we have taken as the type of the variety. 
Mr. Pinder found the latter extending over the Lake district of 
Westmoreland and Lancashire, and on the Yorkshire hills. The 
stations recorded are—Devonshire: Ilfracombe. Yorkshire: Ingle- 
borough. Westmoreland: Langdale; Mardale ; Hawes Water, F. 
Clowes. ? Carnarvonshire: Tre’r Ceiri, C. C. Babington. Forfar- 
shire: Guthrie Woods (larger and rather more divided), A. Oroall. 
Dumbartonshire: Tarbet. Argyleshire: Ardrishiag. Arran, T. M. 
? Wicklow: Powerscourt Waterfall, C. C. Babington. 
4. Smithii (M.). This is a small plant, and has something of the 
general aspect of collina (3), but the fronds are more oblong, and 
the pinnz more equal-sided. The fronds are about a foot high, 
with a stipes of three inches; the pinne of the lower half of equal 
length, and with the tapering apex giving a narrow elongately 
subtriangular-ovate outline. The pinne are opposite, horizontal, 
distinct, and having but slight inequality, even in the lowest, in the 
size of the anterior and posterior pinnules. The pinnules are set on 
at a right angle, the basal ones with a narrow attachment, the rest 
narrowly decurrent on the rachis, ovate-oblong, obtuse, the basal ones 
pinnatifid, the lobes blunt, with distinct acuminate teeth. The 
scales of the stipes are dark, two-coloured, lanceolate, narrower and 
more elongated about the base of the stipes. The plant is doubtless 
related to collina, and is, perhaps, only a modification of it. The Irish 
forms of this affinity are little known, and require a more complete 
investigation than has hitherto been given to them ; and the same 
remark applies to the Irish forms related to dumetorum. We 
describe Smithii from a frond sent by Mr. H. Shepherd, of Liverpool, 
who states that the plant was given to him by Dr. Mackay, as 
that from which Sir J. E. Smith drew up his description of Aspidium 
spinulosum ; so that it is probably the plant from Spike Island, near 
Cove, below Cork, mentioned in English Flora (iv. 279).
