THE CONIFERS OF CHINA. 411 
recorded by Hayata from Formosa, by Matsumura *, and by 
Henry t are included. Ihave also availed myself of Dr. Heinrich 
Mayr's recently published work on the forest-trees suitable for 
growth in Europe i. Dr. Mayr's observations in the forests of 
North China, Japan, and the United States confer great weight 
on his opinions as to the identification and limitations of 
species. 
I am under great obligations to Messrs. Veitch for placing at 
my disposal a complete set of specimens collected by Wilson, 
and to the collector himself for information concerning several of 
the species. I have also to thank Dr. Henry, Sir Dietrich 
Brandis, Sir George Watt, Mr. Duthie, and Mr. C. B. Clarke 
for valuable suggestions and information concerning the 
Himalayan Conifers, some of which are nearly related to 
those of Western China. Those gentlemen, however, must not 
be considered responsible for auy opinions expressed in the 
course of this communication. A comparison of the present 
list with that published in my monograph of the Conifers of 
Japan, already alluded to, presents several features of interest. 
Reference may be made to that paper for notes on the distri- 
bution of species &e. which it is not necessary to repeat on this 
occasion. Some of the trees are closely allied or identical with 
Eastern Himalayan forms, whilst others present similar relation- 
ships to Japanese species. A large number of species are endemic, 
and the proportion of “new species" is large, especially in the 
genus Picea. It is not improbable that subsequent researches 
iu the field may result in the discovery of intermediate forms; 
but the opinions now recorded have been arrived at after 
examination of existing material, repeated comparison of allied 
species, and consultation with Dr. Henry and other botanists 
familiar with the vegetation of China and adjacent countries.
