South Division. 



1. South-east District. Moist coppices near " The Earldoms/' 

 and Landford Common, sparingly. " Near Pewsey," Flor. Marlb. 



2. South-middle District. "Woods at Hare Trip Lane, Devizes," 

 Miss A. Cunnington. 



North Division. 



4. North-west District. Alder copses near Spye Park Lodge. 



5. North-east District. "Neighbourhood of Little Bedwyn 

 parish," Rev. F. H. Bucherfield. " Near Tottenham," Flor. Marlb. 

 Not freqtient in any of the Districts. Fronds usually 2 to 3 feet 

 high, broadly lanceolate, twice pinnate. The lower pairs of pinnas 

 decreasing in size. The segments oblong-lanceolate, and pinnatifid, 

 with pointed teeth. Sori very irregular in form, being sometimes 

 straight, and in other instances so short as to appear nearly circular, 

 although the curved reniform or semi-lunar outline is the most 

 common. It varies much in size and in the degree of division of 

 its fronds, and several forms have received names as varieties. This 

 fern seems to claim precedence in beauty over every oth^r British 

 species. The exquisite grace of its habit, the elegance of its cutting, 

 and the brilliant delicacy of its colour, combine to render it an 

 object of general admiration.
