The plant-species found in this formation are almost the 
same as those in the following formation. 
green Conifers, and they give way to Larix which there forms 
the deciduous Conifer firmation. Larix, being deciduous in the 
winter time, is tolerant of extreme dryness and severe cold. On 
the south, this Larix is found in as high as 2900 m. elevation. 
There it is seen clinging firmly to the ground, so as to prevent 
its being swept away by the wind as Pinus pumila does under 
the same conditions. This Pinus is very common in the alpine 
regions of Japan, but it is entirely absent on tli i- mountain.
