2 ART. I.—B. HAYATA: 
At the same time, as the flora of the island contains a con- 
siderable number of elements from India, including the Himalayas 
and the Malay peninsula and archipelago, it is equally desirable 
for my work that the same should be done with the specimens 
of the regions above mentioned. For a comparison with Japanese 
specimens, the Herbarium at Tokyo will answer fairly well, as 
it includes nearly all Japanese plants, though not exhaustively. 
Chinese plants, however, are here only very poorly represented. 
I, therefore, found it very unsatisfactory to work up so big a 
collection only in the Herbarium at Tokyo. Moreover, as a con- 
siderable number of Chinese plants are represented in the Her- 
barium at Kew, and also in that at Dahlem, and the type speci- 
mens of FRANCHET are especially preserved in the Herbarium at 
Paris, and those of Maxmowicz, in that at St. Petersburg. 
I thought it very necessary for my work to see all the plants 
represented in the principal herbaria of the West. It was my 
great good fortune that I was given an opportunity of visiting 
these different herbaria in order to make an exhaustive com- 
parison of my materials with the collections preserved in them. 
With this intention I first went to Kew taking all my materials 
with me. There I ‘pursued my work with specimens of the 
floras to which our flora is more or less related. The comparison 
made. in most cases, was confined to the flora of Asiatic regions, 
especially, to China, Korea, India, the Himalayas, and the Malay 
peninsula and archipelago ; but, sometimes, it was extended, when 
necessary, to Australia, the Arctic and Antarctic regions, Europe, 
Africa, America and even to Polynesia. I found that many of 
the species of my collections are represented in the Chinese 
herbarium at Kew, and also among the specimens from other 
regions. At the same time, I found also that the greater part
