ATHYRIUM FILIX-FCEMINA. 



The ultimate divisions, being so narrow and crowded, give 

 the frond a feather-like appearance, exceedingly light and 

 elegant. Sori very imperfect, and almost destitute of indusia. 

 Found in 1857 near Skipworth, in Yorkshire, by Mr. J. 

 Horsfall, and now in the possession of Messrs. Stansfield, of 

 Todniordcn. Mr. Swynfen Jervis, of Darlaston Hall, Staiford- 

 shire, has also found a form of this variety at Axminster, 

 which is perhaps more handsome than that found by Mr. 

 Horsfall. The Rev. C. Padley has also found another form in 

 Devonshire.
