FLORA OF THE ISLAND OF SHIKOTAN. 447 
disposal. It is also a cause of great regret that no flora or even list of plants 
growing on Yezo has been published, to which I could refer, except in the 
form of some fragmentary records. When the flora of Yezo and that of the 
Kuriles will have been thoroughly worked out, more evidence upon the 
subject will be available, and my hypothesis will, I hope, be confirmed. 
In my list of the Shikotan Plants, given in the following pages, Bentham 
and Hooker's system is adopted on the whole. The citation of the literature 
under the species and varieties is restricted to more important works. 
Besides certain general works, reference is also made to some of the 
prineipal floras of the neighbouring countries. The following publications, 
which deal with Hokkaidó (Yezo) plants, are frequently referred to :— 
1. Mryvane, K.—The Flora of the Kurile Islands, in Mem. Boston Soc. 
Nat. Hist. iv. 1890. 
2. Marsuparra, H.—List of Plants collected in Kurile Islands by 
T. Kitahara, in Tókyó Dot. Mag. ix. 1895. 
3. YanE, Y., and K. Yenpd.—Plants of Shumshu Island, tbid. xviii. 1904 
(in Japanese). 
4. Takena, H.—Beitriige zur Kenntnis der Flora von Hokkaidó, ibid. 
xxiv.-xxv. 1910-11. 
Lycopodialen Hokkaidós nebst denen von Japanisch-Sachalin,

The accompanying Table of Distribution of the Shikotan Plants (pp. 500- 
508) is constructed so as to show all the species, subspecies, varieties, and 
sometimes forms, occurring in the three larger islands of Japan, the principal 
islands of the Kuriles, where plants have been collected, the adjacent countries 
in Eastern and North-eastern Asia, and North America and Europe. For 
this purpose T have carefully consulted the numerous floristic works of those 
districts, as well as specimens preserved in the Kew Herbarium, As to the 
data concerning the Kuriles, and especially of those other than Shikotan, 
I am deeply indebted to Professor K. Miyabe for the privilege of working in 
the Herbarium of the Agricultural College, Tohoku Imperial University, 
Satporo, and for placing all his unpublished notes and specimens at my 
disposal (1909). To Professor J. Matsumura I tender my sincere thanks 
for giving me the opportunity of examining the specimens collected by 
Mr. T. Kitahara and enumerated by Mr. H. Matsudaira, which are preserved 
in the Herbarium of the Science College, Tókyó Imperial University (1909), 
[ also take this opportunity of thanking Lieut.-Col. Sir David Prain and 
Dr. Otto Stapf for their courtesy in allowing me to use the Herbarium 
and Library of the Royal Botanie Gardens, Kew (1910-12). 
The map on p. 436 has been based on five different Japanese maps,
