Elegaxs, WoUaston. (Fig. 73.) — Found near Worthing, in 

 Sussex, by Mr, G. B. AVollaston, of Chiselhurst, and also in 

 Ireland, by Mr. SwyiLfen Jervis, of Darlaston Hall, Staffordshire. 

 This interesting dwarf variety is remarkable for its distinct 

 acuminate teeth. The basal anterior pinnules are considerably 

 the largest, and almost pinnate. In some fronds the pinnules are

 to the prominent and large sjiiny teeth, makes the form 

 distinct.
