rOLYrODIUM VULGARE. 



irregular or interrujjted lobes; and here and there altogether 

 absent. Occasionally irregularly bifid, multifid, or curiously 

 laciniated. Fronds linear-lanceolate. Found in 1851 and 1858 

 at Tunbridge Wells, Kent, by Mr. G. B. Wollaston. 



KRAsrEDOUMENON, Loioe. (Fig. 23.) — See Marginatum, 

 Moore, for remarks on this beautiful Fern. 



Laciniatum, Moore. — The lobes in Laciniatum vary in 

 length on the same frond: they are simply, but irregularly 

 notched and somewhat crisped. This variety approaches 

 Interruptum, and is doubtfully distinct. Laciniatum puts on 

 so many forms that it is difficult to procure a characteristic frond; 

 under these circumstances I have refrained from giving an 

 illustration. 



LoBATUM, Sidehotham, MS. (Fig. 20.) — Found by Mr. 

 Joseph Sidehotham, about 1843, in Troutbeck Valley, near 

 Ambleside; subsequently near Bowness, and near Beddgelert, 

 in North Wales. Fronds large; lobes broad. Auriculate on 

 the upper edge of the lobes next the rachis, and crenulate; 

 the upper lobes not auriculate nor crenulate. Sori copious, 

 but small. A distinct variety.
