Nr. 3] SOME VASCULAR PLANTS FROM SAGHALIN 7 



undergrowth consists chiefly of Myricn gale var. tomentosa 

 averaging aboul 1 metre high. The soil is here swamp3\ 



C. The Pine foresls. (Abies sachalinensis). These are as a 

 rule extremely dense, shutting out all light from the soil, which 

 accordingly bears, as a rule, liltle else beyond moss and lichens. 



A great part — the major portion, we may say, — of the 

 forest on the island has been harried by fire, and such piaces 

 are practically impenetrable owing lo the tree trunks, large and 

 small, which have fallen \vholly to the ground or interlaced, in 

 a chaotic disorder which renders it impossible to force a way. 



VII. Highland forest region. The hills are, as a rule, 

 covered only with pine (Abies sachalinensis). In piaces where in 

 earlier times fires have taken place however, we find, in addition 

 to the later growth of young pine, immigrant birch and mountain 

 ash (Sorbiis auciiparia var. japonica), these being, at any rate in 

 piaces, very densely packed. The ground is here for the most 

 part grassy, with occasional patches of moss and lichen.
