 Scotland. Mr. G. Don. 



Perennial ; flowering in June. 



This is a very remarkable plant, quite unlike any other known 

 species, and does not appear to have been found in any place out of 

 England. It is very rare, and we have not been able to procure wild 

 specimens ; but our cultivated ones do not differ from them, except 

 being rather larger and stouter plants.
