DisTRiB. Saghalin. 



In 19 14, Mr. E. H. Wilson of the Arnold Arboretum kindly gave us an ex- 

 cellent specimen of what he considered as Abies sachalinensis, var. nemorensis Mayr, 

 which he had collected at Konuma, near Toyohara in Saghalin. The tree is said 

 to be growing mixed with Abies sachalinensis . Among the specimens collected 

 by Mr. Tsutom6 Miyake at Naikotoru in the west coast of Saghalin in 1907, we 

 found also those of the same fir bearing well matured cones. 



At the time of writing the "Flora of Saghalin", we availed ourselves of these 



■ 



specimens in delineating the characters of Abies nemorensis Miyabe et Kudo under 

 the assumption, that it corresponds to the var. nemorensis of Mayr. But we. found 

 on a careful study of these Saghalin specimens many prominent differences between 

 the typical Saghalin Fir and the plant under consideration, that we have come to 

 the conclusion that the Wilson's Fir must be elevated to the specific rank. 



Later, as we have remarked under the var. typica of Abies sachalinensis, we 

 have found that the var. nemorensis Mayr is a rare abnormal "form of Abies sachalin- 

 ensis and should not be confounded with a new Saghalin Fir discovered by Messrs. 

 Wilson and Miyake. 



Although, according to Mr. Wilson, there are no apparent differences in the 

 habit and general appearance of this fir and those of Abies sachalinensis, yet when 

 we come to make a closer study of the cones and their parts, we could not help to 

 consider them as two distinct species. 



The elliptical, violet or bluish black cones with included bracts, with the fewer 

 larger cone-scales which are slightly pubescent not along the outer upper margin, 

 but a little lower down toward the 'middle, are quite characteristic. From Abies 

 VeitcJiii Lindl., to which the cone of our fir shows a slight resemblance, we can 

 easily distinguish it by the shape and size of its cone and its parts.
