Mrs. Chanter’s Prickly-toothed Buckler Fern—L. nuatara Cuastent—(Puate XXIV) is а re 
markably distinct form of the species, differing obviously in the narrowed form and attenuated apex of its 
во distant pinn, and its distinct blunt pinnules, Tt is of medium size, growing from a 
and a half to two fect in height, the fronds growing nearly егесі, and being of a lanceolate or oblong 
lanceolate form, with the baso somewhat narrowed, and the apex attenuated. The stipes, rachis, and 
under surfaco of the fronds are clothed with sessile or very shortly-stalked glands. The stipes is 
clothed rather plentifully with lanceolate and ovate-lanceolate entire scales, which are of various sizes, 
brówn, with a dark central streak, and tipped by a longish, weak, bristle point. The fronds are 
bipinnate ; the pinnae distant, somewhat spreading, and more or less twisted, so that the upper surface 
is directed towards the zenith; the lowermost pair are very unequally deltoid, their posterior basal 
pinnules being more than twice the length of the anterior ones, and these posterior pinnules are almost 
themselves pinnate; the next pair is unequally deltoid, but the posterior pinmule is only al 
than the anterior ; the inequality is nearly lost in the next and the succeeding pinnt 
adually to the apex. ‘The basal pinnules of these upper pinne are nearly oblong, their 
baso being but little broader than their apex, which is very blunt; they have a narrow stalk-like 
tachment, which becomes broader and decurrent in the pinnules higher up the pinna. Тһе pinnules 
ге more or less deeply pinnatifid according to their position on the pinnae, and the lobes, which are 
bluntly oblong, have a few coarse distinct teeth, each of which is terminated by a bristle-ike point 
‘The sori, which form a line on each side near the midrib of the smaller pinnules, amd а double line 
along the lobes of the larger ones, are covered by reniform indusia, which are fringed with small stalker 
glands at the margin, This very marked variety was discovered in 1854, by the Rev. J. М. Chanter 
‘and Mrs. Chanter, after whom it has been named, at Hartland, on the north coast of Devon, where it 
was found growing in moderate quantity within a limited area, and accompanied and surrounded by 
other common forms of the species, We are indebted to Mr. Chanter for the specimen figured, and 
for living plants collected during the present year, from which latter our description has heen prepared 
The Linear Prickly-toothed Buckler Fern—L. оплата axcusra—is a variety having the outline 
and general features of the erect typical form of L. spinulosa, but possessing also the particular 
characteristics of Z. dilatata, Tt has narrow lincar-Ianccolate bipinnate fronds, about two feet high ; the 
stipes moderately furnished with large attenuately lance-shaped pale-brown dark-centred scales ; the 
pinna: shortly deltoid, and the lower two or three pairs very unequally so, the p 
erior pinnules being 
much the largest; tho pinnules narrow, oblong, obtuse, deeply pinnatiid with ovate or oblong lobes, 
having aristato teeth. "The sori are small, abundant, occurring from the base to the apex of the frond, 
and covered by small indistinctly glandular convex indusia 
The Alpine Prickly-toothed Buckler Fern—L. piarara anmxa—has fronds of the outline of 
ordinary states of Z. spinulosa, that is, strajght-sided, broadly linear, seareely lanceolate ; they are almost 
tripinnate below, bipinnate upwards ; the pianos ovate-lanecolate, or ovate, ascending, membranous in 
texture, and bearing two rows of large р 
ninent sori, of which the covers, which are very evanescent,
