FETALOPHYLLUM. 429 



I. Connor Hill, near Dingle, Profemor S. 0. Li/ul/jcrt/, 1873. 



Found on the Continent. 



Obs. — This, about the rarest of all our British species, was 

 discovered by Mr. C. Lyell, and justly named by him in honour 

 of Sir Wm. Jackson Hooker, whose magnificent " British Junger- 

 mannia? " is a monument of the intimate and loving knowledge 

 he had of this group. 



It is so distinct a species as to be impossible to be mistaken 

 for any other.
