It is now generally admitted that this species as described by Presl 

 includes three distinct forms, which are elevated to the rank of species by 

 Mr. Wollaston. We append the most obvious of their characters as briefly 

 as possible under their several heads. 



A. Proplnqua-mas {Wollaston). (Filix-mas abbreviate*, Moore.) (Fronds 



and pinnae concave, pinnules biserrate, colour dull pale green ; perfectly 

 deciduous, texture soft ; indusium embracing spore-cases, persistent, 

 entire). 



Dry hedge-banks and woods. Extremely rare. 



Near Carngaver, Co. Down, R. LI. P., 1882. 



B. Fillx-mas (Presl). (Fronds and pinnae convex, pinnules serrate or 



biserrate ; colour shiny pale green ; texture papery ; very partially 



deciduous ; indusium not embracing spore-cases, eventually evanescent, 



disrupted). 



Woods, glens, roadsides, &c. Common.
