54 ASPIDIUM OREOPTERIS. 



In the lake districts of Westmorland and Cumberland it is very 

 abundant. 



Extends over the whole of Europe. 



Fronds pinnate, lanceolate in form; pinnae opposite, the basal 

 ones obtusely triangular, about the centre of the frond linear- 

 lanceolate. 



Veins forked, and bearing sori near the apices. 



Sori moderate-sized, round, forming a sub-marginal series. 



Indusium small and thin. 



Length of frond from one to three feet. Colour brilliant 

 green. 



The fronds of this species are fragrant. 



Mr. Moore, in the "Nature-printed Ferns,"gives two varieties : 



1st. — Truncata, Wollaston. Found near Tunbridge Wells, by 

 Mr. Wollaston, a monstrosity, having the apices of the frond 

 and pinnae ending abruptly. 



2nd. — Crisjpa, Moore. Found on the Clova Mountains, by 

 Dr. Balfour. The pinnules are undulated. 



Plants of this Fern I have gathered wild at Oxton Bogs 

 and Bui well, Nottinghamshire; at Wincham, near Northwich, 

 Cheshire; and about Ambleside and Grasmere. For other 

 specimens I am indebted to Sir Oswald Mosley, Bart., of 

 Rolleston Hall; and to Mr. Joseph Sidebotham, of Manchester. 



It is in the following Catalogues: — Messrs. Veitch, of Chelsea; 

 Rollisson, of Tooting; Sim, of Foot's Cray; Cutbush, of High- 

 gate; Kennedy, of Covent Garden; Stansfield, of Todmorden; 

 E. G. Henderson, of St. John's Wood; Cooling, of Derby; A. 

 Henderson, of Pine-apple Place; and Young, of Taunton. 



The illustration is from a plant in my own collection.
