Obs. — This is a very distinct species and not likely to be con- 

 fused with any other, the curiously convolute-complicate leaves, 

 which in the common form are usuall}^ bidentate, readih^ enabling 

 us to recognise it. A large, more erect form has been found on 

 the Continent, and also at Tyn-y-Groes, North Wales, by Mr. 

 Holt ; it has leaves usually tridentate, but no other character of 

 importance has yet been observed. 



Hab. — Growing on rotting wood, heaths or rocks, in woods 

 or shady places. Somewhat rare, very rare in fruit.
