POLYPODIFM VUJ.GARE. 



Marginatum, Moore. (Fig. 22.) — Found in Kent, by 

 Mr. G. B. Wollaston, and at Windermere, by Mr. Clowes. A 

 remarkable and scarce variety, somewhat larger than the ordinary 

 form. The lobes of the frond blunt, the epidermis on the under 

 side of the lobes, irregularly ruptured, split away as it were 

 from the margin of the lobes, and receding towards the mid- 

 vein. Sometimes eared as in Auritum, as is the case in the 

 Windermere form. Mr. Clowes' variety is very different, as the 

 wood-cut illustration will shew. It seems desirable to separate 

 these Ferns, at all events provisionally, and this I propose to do, 

 using the Greek word, instead of the Latin, the name of Clowes' 

 Fern will therefore be variety Kraspedoumenon.

MuLTiFiDUM, Moore. (Fig. 24.) — This belongs either to the 

 ordinary form or the serrated section; it has the apices of the 

 frond bifid or multifid.
