1i INTRODUCTION. 
As to the total number of species recorded from the island, I 
may add that in the preceding fascicle it was stated to be 2660 
species, belonging to 836 genera and 156 families. Since then just 
one year has elapsed. During that time I have secured many 
colleetions and a number of genera and new species have to be 
added to our Formosan flora. The genera to be added at this 
time together with a few that appeared in the "Tokyo Botanical 
Magazine a few months ago, are given in the following table. 
Gonocaryum C'issus Semecarpus 
Pachysentria Medínilla Glibertia 
Litosanthes Chimaphila FErycibe 
Blachia Pachysandra Sarcococca 
Mitrastemon Cremastra Cypripediwm 
lone Listera Oreorchis 
Teniophyllum Drimotenium Peranema 
Lecanopteris. 
The species newly added or now to be added number as 
many as 47. Among these stands Rafflesiacesw or .Mitra- 
stemonacee, a new family proposed by Mr. T. MakiNo, and 
represented in Formosa by  Mitrastemon | .Kawa-Sasakii | MAYATA. 
Thus up to the present date, the total number of the flora, so far 
as is known, is 2707 species, belonging to 858. genera and 157 
families. 
In conclusion, |I avail myself of this opportunity to express 
my obligations to the officials of the Government of Formosa who 
have helped me in the collection of materials and in the publiea- 
tion of my work.
