ASPIDIUM ANGULARE, Var. Aristatum. 



PLATE LVI. 



Polystichum angulare, var. aristatum, Moore. 



Aspiditini — Shield Fern. Angulare — Angled. Aristatum — Awned. 



In the Section Polystichum of Authors. 



The above Fern was found in Sussex, by Mr. Wollaston, 

 and subsequently near Burnley, Lancasbire, by Mr. Stansfield. 



Its destructive feature is in the bristly points of the serra- 

 tures being more developed than usual, and turning upwards. 

 The stipes is proliferous. 



It is a pretty Fern. 



For additional information on the varieties of angulare, see 

 vol. vi, pages 68 to 71, of Lowe's "Natural History of Ferns," 

 and pages 67 and 110 of the present volume. 



My thanks are due to Mr. Stansfield, of Todmorden, for 

 the frond figured.
