OF LASTREA REMOTA, A. BR., IN ENGLAND. 193 
him as a distinct species, and was described under the name of 
Aspidium remotum *. Yt has subsequently been adopted as а 
species by Kunzet, by Еве}, by Mettenius§, and by Koch |. 
Braun's plant, as far as I am aware, has hitherto only been re- 
corded as a native of Southern Germany, to which must now be 
added the English habitat of Windermere, Westmoreland. 
In general character and aspect the plant very much resembles 
the vigorous examples of Lastrea spinulosa which are sometimes 
met with, having like that fern narrow elongate erect fronds ; but 
its structure agrees more closely with that of L. PFiliz-mas, than 
which, however, it.is once more divided. It has neither the ap- 
pearance nor the structure of L. rigida. The plant appears to me 
to have very reasonable claim to specific rank, though on this 
point it is in these days hopeless to expect unanimity of opinion. 
І append the specific character and synonymy of this addition 
to the British flora, together with a full description of the West- 
moreland plant. 
LasTREA REMOTA: fronds oblong-lanceolate, subtripinnate, smooth ; 
pinnze acuminate, distant below; pinnules distinct, pyramidal or 
ovate-oblong, acute, shortly petiolate below, sessile, with a narrow 
attachment, or more or less adnate upwards, the basal ones pinnatifid 
almost to the costa; lobes oblong, blunt, serrated, the serratures 
acute mucronulate; sori copious over the whole frond, biserial near 
the costa; indusium reniform, obscurely eroso-dentate, persistent, 
without glands ; stipes and rachis stout, scaly.

Caudez......... Stipes a foot long, stout, clothed with numerous scales 
of various size, some ovate-acuminate, 3 of an inch long, others smaller, 
lanceolate or linear, terminating in a lengthened hair-like point, the 
margins slightly wavy or toothed; along with these larger ones occur 
numerous others, which are minute, ovate caudate, and peltately 
attached. Rachides, both primary and secondary, furnished with scales, 
which become smaller upwards. Fronds (including stipes) 3-4 feet
