below the apex, and again brandling near the tip into two 

 or three hirge dccurrent ultimate pinna). My thanks are due 

 to Mr. Mapplebeck, for fronds. 



Interruptum, Clapham. (Fig. 567.) — A pretty variety. 

 Distinct, from the interrupted character of its pinna), which are 

 variously formed, some crenate and others laciniate. Sometimes 

 three fourths of the frond will be normal, in others scarcely 

 a single pinna; the pinna) either absent or depauperated, the few 

 larger ones very narrow and deeply divided, the apex caudate. 

 Length of frond eight inches. I am indebted to Mr. A. Clapham, 

 of Ilamsdale Bank, Scarborough, for a plant.

Crenato-lobatum, Moore. (Fig. 568.) — Found at Nettle-

 Slade, near Linton, in Devonshire, by the late Mr. C. Jackson. 

 Vigorous and somewhat normal, with fronds upwards of a foot 

 in length. The pinnae, however, (which are large, oblong- 

 obtuse,) are profoundly but finely crenate-lobate, giving a 

 uniform-toothed margin to them. My thanks are due to Mr. 

 C. Elworthy for fronds. 



Depauperatum, Wollaston. (Fig. 569.) — Found in 1853, 

 in Ireland, at Black Head, County Clare, by Dr. Allchin; and 

 in 1855, at E,ydal, in Westmoreland, by Mr. G. B. Wollaston. 

 It is rare, though intermediate forms have been discovered at 

 Firby, in Yorkshire, by Mr. C. Monkman, of Malton, and at 

 Whitbarrow, in Westmoreland, by Mr. F. Clowes, of Windermere. 

 Remarkable for its interrupted or depauperate character. The
