near C'lithcroc, in liauciishire, luul at (Jt)rby Castle, near 

 Carlisle, by myself. Fronds quite tripinnate. The i)innules 

 are divided to the midrib at the base, and the brief oblong 

 blunt secondary pinnules are toothed along their sides, or 

 even pinnatifid with dentate lobes. Length of frond two feet, 

 width eight inches. Pinnic Avidest in tlie widest part of the 

 frond, narrowing and shortening towards the base and apex. 

 This variety differs in the pinnatifid character of the secondary 

 lobes from incisum. It is therefore a more decompound form 

 of incisum, and very graceful. No illustration is necessary.

 dissectum in the open irregular manner in which the pinnules 

 are cut, and having intermediate characters between this variety 

 and laciniatum. An elegant Fern, with fronds eighteen inches in
