THE BROAD PRICKLY-TOOTHED BUCKLER FERN. 233 
by Miss M. Beever, to whom we are indebted for specimens, 
sufficiently accords with the imperfect examples of the Aspidium 
dumetorum in Sir J. E. Smith's herbarium, as to be considered the 
same plant, and we so regard it. This plant has elongate-triangular- 
ovate fronds seldom exceeding a foot in height, and very glandular, 
especially on the stipites, rachides, and lower surface of the veins ; 
they are bipinnate, the pinne concave and bluntish; the pinnules 
broad oblong, or oblong-ovate, convex, crispy, and coarsely-toothed, 
the teeth broad and acuminately tipped by a small bristle. The stipes 
is sparingly clothed with lanceolate scales of variable width, and of 
a pale-brown colour, sometimes scarcely at all darker in the centre, 
sometimes distinctly two-coloured, but always having their margin 
fimbriate. The sori are large, distinct, produced over the whole 
under surface, and covered by indusia, which are prominently fringed 
with stalked glands. Young plants of this form, but a few months 
‚old, and three or four inches high, bear fronds which are abundantly 
fertile. Miss Beever’s plant was gathered in Silverthwaite, and in 
other rocky Fells of that part of Westmoreland; and the same form 
has been obtained by Mr. F. Clowes from Hawes Water, and 
by the Rev. G. Pinder, from Elter Water. Sir J. E. Smith's 
dumetorum came from Cromford: Moor near Matlock, in Derby- 
shire; from Westmoreland; from Mount Glyder overhanging Llyn 
Ogwen in North Wales; from near Phainon Vellon; and from 
Rivelston Wood, near Edinburgh. The plants from the following 
habitats we believe to be the same variety, inasmuch as they 
agree in the pale-coloured broad lance-shaped, fimbriated scales 
of the stipes and crown, in the dwarf habit, and subtriangular or 
ovate fronds, in the glandulose surface, and the large distinct sori; 
and differ from that first described, in little but the absence of the 
crispy aspect of the pinnules, while they present but trifling variation
