THE BRITISH FERNS. 
apex is ramosely multifid ; the pinnules are small oblong, blunt, and toothed. 
It was found in the Clova mountains, and was sent to us by Messrs. Stansfield, 
who state that all the fronds are more or less proliferous. 
Another ramose form, too young as yet to be 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 be inserted after Z. Filix-mas (vol. i. p. 208). 
THE REMOTE BUCKLER FERN. 
LASTREA REMOTA. 
L. fronds oblong-lanceolate, subtripinnate, glabrous; pinne acuminate, distant 
below; pinnules distinct, pyramidal or ovate-oblong, acute, shortly petiolate below, 
sessile with a narrow attachment, more or less adnate upwards, the basal ones pinna- 
tifid almost to the costa ; lobes oblong blunt serrated, the serratures acute mucronu- 
late; sori copious over the whole frond, biserial near the costa ; indusium reniform, 
persistent, obscurely eroso-dentate, without glands; caudex stout ascending ; stipes 
and rachis stout scaly.

POLYSTICHUM REMOTUM, Koch, Syn. 2 ed. 979. 
ASPIDIUM RIGIDUM, B. REMOTUM, A. Brawn, Doll, Rhein. Fl. 16. 
Caudex stout ascending, with a thick scaly crown. 
Vernation circinate. 1 
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 termi- 
nating in a lengthened hair-like point, the margin slightly wavy or toothed ; along 
with these larger scales occur numerous others, which are minute ovate caudate and 
peltately attached. Rachis both primary and secondary, furnished with scales which 
become smaller upwards. | 
Fronds 3-4 feet high, erect, narrow oblong-lanceolate subtripinnate, smooth. 
Lower pinne 3-4 inches long ovate-acuminate, central ones 6 inches long, linear- 
oblong acuminate, all ascending, opposite or subopposite and distant below. Pinnules 
(basal ones of second pair of pinnæ) 14 inch long, shortly petiolate, pyramidal or 
pyramidal ovate, acute, pinnatifidly divided nearly to the costa, almost pinnate ; 
lobes oblong, about ¿ of an inch long, obtuse, the lowest ones sublobate at their base, 
otherwise serrated, the serratures most numerous and, prominent at the apex, acute, 
mucronulate. The pinnules become gradually less pyramidal or ovate, and more 
oblong, at length linear oblong, as they recede from the main rachis ; below, except 
in the case of the lowest, they are also sessile, with a narrowed attachment, but 
become gradually more and more adnate upwards. The pinnules of the upper pinna 
resemble the smaller pinnules of the lower ones. 
Venation in the larger lobes consisting of a flexuous primary vein or costa, from which 
alternate veins proceed towards the serratures, sometimes becoming branched, the sori 
being situated medially on the simple, and close above the fork on the branched ones.
