Dr. Mayr, who has lived in Japan during the last few years, pro- 

 poses to refer P. Alcoquiana to P. hicolor. For the present I prefer 

 to retain the name P. AlcocUana until some of our plants can be 

 determined.

Habitat. — According to Dr. Mayr, this Fir is not much more 

 widely distributed than P. polita. It is only to be found in Central 

 Japan from 35^° to 38° N. ; further north it does not exist. In 

 a vertical direction, it belongs to the temperate and cold Conifer 

 woods, but is also to be found here and there in the cold Beech 

 forests in single specimens. 



P. cserulea Hudsoni. It has not yet been determined to which 

 species this variety belongs.
