apex is ramosely multifid ; th e pinnules are small oblong, blunt, and toothed.
I t was found in th e Clova m ountains, and was sent to us by Messrs. Stansfield,
who state th a t aU th e fronds are more or less proliferous.
Another ramose form, too young as y et to he described, a seedling raised by Mr. J.
Crossfield of Arnside, seems likely to be permanent.
Lastrea remota.
This species which has recently been determined as a native of England,
should bo inserted after L. F ilix -ma s (vol. i. p. 203).
THE REMOTE BUCKLER EERH.
LASTREA REMOTA.
L. fronds oblong-lanceolate, subtripinnate, glabrous ; pinnæ acuminate, d istan t
below ; pinnules distinct, pyramidal or ovate-oblong, acute, shortly petiolate below,
sessile with a narrow attachment, more or less adnate upwards, th e basal ones pin n atifid
almost to th e costa ; lobes oblong b lu n t serrated, th e serratures acute mucronu-
la te ; sori copious over th e whole frond, biserial near th e costa ; indusium reniform,
persistent, obscurely eroso-dentate, without glands ; caudex stout ascending ; stipes
and rachis stout scaly.

Caudex stout ascending, with a th ick scaly crown.
Vernation circinate.
Stipes a foot long, stout, clothed with numerous scales of various size, some ovate
acuminate three-quarters of an inch long, others smaller lanceolate or linear te rm in
atin g in a lengthened hair-like point, th e margin slightly wavy or toothed ; along
w ith the se larger scales occur numerous others, which are minute ovate caudate and
p eltately attached. Rachis b o th primary and secondary, furnished with scales which
become smaller upwards.
Fronds 3-4 feet high, erect, nan-ow oblong-lanceolate subtripinnate, smooth.
Lower pinnce 3-4 inches long ovate-acuminate, central ones 6 inches long, linear-
oblong acuminate, all ascending, opposite or snbopposite and distant below. Pinnules
(basal ones of second p air of pinnæ) inch long, shortly petiolate, pyramidal or
pyramidal ovate, acute, pinnatifidly divided nea rly to th e costa, almost pinna te ;
lobes oblong, about | of an inch long, obtuse, th e lowest ones sublobate a t th e ir base,
otherwise serrated, th e serratures most numerous and prominent a t th e apex, acute,
mncroniilate. The pinnules become gradually less pyramidal or ovate, and more
oblong, a t len g th linear oblong, as th ey recede from th e ma in rachis ; below, except
in th e case of th e lowest, th e y are also sessile, with a n an ’owed attachment, b u t
become gradually more and more adnate upwards. The pinnules of th e u p p er pinnæ
resemble th e smaller pinnules of th e lower ones.
Venation in th e larger lobes consisting of a flexuons p rimary vein or costa, from which
alternate veins proceed towards th e seiTatures, sometimes becoming branched, th e soii
being situated medially on th e simple, and close above th e fork on th e branched ones.

This recent addition to our F ™ F l » ' ' ' m n e h resembles in general c t o
and asnect those vigorous examples of i . cristata v. spmulosa which are sometimes

Tal c eristics ft differs materially from th a t plant, - ¿ / S' ' ”- “XVfo ms
with i Filioe-mas. From i . Filix -mas itself, th e incised pyramffial-pmnuled forms
of which most nearly resemble it, i t may he separated hy th e circumstance th a t its
fronds are once more divided, heing trip in n ate. I t appears
to specific rank, although Professor Braiiu hy whom i t was first described, is now
inclined to regard ft as a more divided form of th e Common Male Fern.
