Obs. — A very rare and distinct species, first collected by 

 Dillenius on Snowdon in 1740; its brown colour, shape and 

 position of the antical lobe of leaf readily distinguish it from any 

 of the ciliate Scajjajiup, with the exception of S. nintbosa, which see. 



I am averse to changing any well-established and appropriate 

 specific name, but as Dillenius described and figured so accurately 

 and Withering published the species so many years before Hooker, 

 who evidently was not aware the species was already published, 

 I feel compelled to adopt the earlier one.
