 end; h)bes deeply cut, forming a row of coarse serrate teeth 

 along the edges of the pinnules. This is one of the handsomest 

 and most densely tasseled of the multifid varieties. 1 am 

 indebted to Mr. Elworthy, of Nettlecombe, for fronds.

Erosum, IVollaston. (Fig. 337.) — Found in Kent, near Tun- 

 bridge Wells, by Mr. G. 13. WoUaston; at Marwood, in 

 Devonshire, by the E,ev. F. Mules; and on Cahir Conree, near 

 Tralee, county Kerry, by Dr. AUchin. This variety is normal in 

 size, and lanceolate and almost normal in form, the pinnae also 

 normal in size. The pinnules mostly variously depauperated, 

 and therefore unequal in size, the lobes also disproportionately 

 developed, the frond having an irregularly laciniated appearance; 

 occasionally the pinnules arc somewhat normal, blunf, oblong, 

 pinnatifid, decurrent, the lobes unequal, with brief blunt teeth. 

 The pinnules occasionally bifid or multifid. An approach to 

 this variety, yet more normal in its characters, has been found 

 in the Isle of Man by Dr. Allchin. 



Ekosum-minus, 3Ioore. — Found near Windermere, byj Mr. 

 F. Clowes. An elegant diminutive form of erosum. Fronds
