58 FERNS OF THE LAKE COUNTRY 



pinnules deeply pinnatifid, with blunt oblong lobes, 

 sparingly toothed, the teeth coarse acuminately aris- 

 tate (or bearded), mostly at the apex. Sori mostly 

 arranged in two lines along the pinnules, as in the 

 smaller forms of the species, and covered by gland- 

 fringed indusia. This variety was first brought into 

 notice by the Eev. Gr. Finder, found by Elter Water, in 

 Langdale, and by Mr. Ecclestone at Torver, near Conis- 

 ton. This last is rather larger and more divided, with 

 concave pinme and strongly convex pinnules ; it is also 

 somewhat glandular. 



L. alpina is remarkable for being more delicate and 

 membranaceous than other forms of the species ; the 

 fronds normally oblong, or straightsided, with the 

 point tapered off as in the typical spinulosa, but in 

 some specimens even broadly ovate, almost or quite 

 tripinnate below, bipinnate upwards. Found by Mr. 

 Clowes at Hawes Water.
