OF LASTKEA REMOTA, A. Bll., IN ENGLAND. 193 



him as a distinct species, and was described under the name of 

 Aspidium remotum*. It has subsequently been adopted as a 

 species by Kunzef, by Fee J, 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. Filix-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. 



I 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 ; 

 pinnae 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.

Caudex Stipes a foot long, stout, clothed with numerous scales 



of various size, some ovate-acuminate, | 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 

 high, erect, narrow, oblong-lanceolate, smooth, subtripinnate. Lower 

 pinnce 3-4 inches long, ovate acuminate ;" central ones 6 inches long, 

 linear-oblong acuminate, all ascending, opposite or subopposite, and
