Distrib. extends to Europe, North India, Japan, East Siberia, Kurile 

 and Aleutian. 



The species seems to vary oyer a very wide range ; from a small 

 flowered form to a large one. There are three very near species i.e. P. 

 grandiflora L., P. gelida C. A. Mey., and P. fragiformis Willd., each 

 having gradual transition between them. No barrier whatever can be 

 systematically established between them, so slowly do they pass from one 

 to another. Hooker have, I think, a well grounded reason to render the 

 three species into one— that is P. gelida O. A. May. If we admit this 

 opinion, my Morrison specimen must fall into the range over which P, 

 gelida reigns. The Morrison species does, however, it should be mentioned, 

 come nearer to the Japanese form than the Kulile one.
