ATHYRIUM FILIX-FGEMINA. 



NuDATUM, Moore.' — Found in Devonshire by the late Mr. 

 C. Jackson. A dwarf curious variety. Stipes red. Frond 

 abrupt. Pinnae variable, the upper ones longest. Fronds 

 narrow, from the abrupt shortening of most of the pinnae. 

 Remarkable for a bare space on the rachis half an inch long, 

 devoid of pinnules. The ajiical portions occasionally forked 

 or branched.

Plicatum, Padley, MS. (Fig. 450.) — A most singular form 

 found near Nettlecombe, by Mr. Charles Elworthy. Length of 

 frond fourteen inches, width in the widest part of the frond 

 nearly four inches. Pinnse narrowing to the base and apex, 

 descending at the base, horizontal in the centre of the frond, and 

 ascending towards the apex; alternate and distant, broadest at 

 the base, and gradually tapering to an acuminate apex. Pinnules 

 plicate and crowded. Sori crowded. I am indebted to Mr. 

 Elworthy for fronds.
