forestage still can be seen along the ravines ; basin of which is com- 

 posed of black basalt and now came to our sight washed by the 

 running water. The vegetation of Paiktusan is therefore newly deve- 

 loped after that eruption, and is now composed of alpine belt of Paiktu- 

 san-proper and the Larix woods surrounding it. This Salix is in the 

 alpine belt and grows side by side with Dryas octopetala v. asiatica, 

 Phyllodoce cxrulea, Rhododendron confertissimttm, Rhododendron Re- 

 dowskianum, Vaccinium uliginosum etc. 



The distance from the old home of this willow is too iar as a 

 Salix ; but I think when the Plora of Okhotsk regions is more completely 

 cleared up, we shall find that this grows there and thus the present 

 distribution is very natural.
