Hob. Kurile Islands (fide Regel). Etorofu, at Shana and Shibetoro. 



This variety is also found throughout Japan, but is especially common towards the 

 north, where it attains its greatest size in fertile valleys.

Hob. Shikotau, on exposed hillsides facing the harbor. 



Our plant is about a foot and a half in height with a stem bent in a somewhat zigzag 

 way. Its leaflets are very small, inch in length, and glandular-pubescent beneath. 

 The present variety is very much rarer in Japan than the above, growing mostly in 

 the alpine districts. It is not yet known from Saghalin, Kamtsehatka and Eastern Si- 

 beria. 



The species is very widely distributed in Europe, Africa, Asia and Alaska.

The plants which are found throughout northern Japan correspond exactly to the typ- 

 ical specimens from Kamtsehatka and Saghalin. Those which were collected by Max- 

 imowicz in southern Japan, and which he considers as a variety of this species, have the 

 leaves somewhat resembling those of Anemone umbrosa, though considerably smaller. 



There are a few specimens in the Gray Herbarium labelled A. umbrosa, which were col- 

 lected by W. P. Blake in "K Japan." A similar specimen was collected in the vicinity 

 of Sapporo. They have certainly a striking resemblance to the Ussuri specimen of A. 

 umbrosa in the shape and proportion of the leaves and flowers, and in the nature of the
