Found on the Continent and in North America. 



Obs. — This very rare British species, which is only found in 

 alpine regions, cannot be mistaken for any other if seen with its 

 laterally inserted perianth ; when barren it is easily distinguished 

 from any of the forms of Junf/. bantriensis, Hook., by its claw- 

 like segments of the leaf and the large obliquely projecting 

 stipules. 



Harpanthus scutatus (W. & M.), found on lower elevations, is 

 a smaller plant of different colour, shape and texture of leaves, 

 which see.
