204 DR. M. T. MASTERS ON THE DISTRIBUTION OF 
TonnEYA GRANDIS and 7. Fargesii are exclusively Chinese, whilst 7. nucifera 
occurs also in Japan. 
GINKGO BILOBA, an interesting survival of over sixty species known in a 
fossil state, is found both in China and in Japan generally in a cultivated 
condition in the vicinity of the temples, but Mrs. Bishop records it as native 
both in Western China and in Northern Japan. 
Dacrypium Beccari of Parlatore is reported from Hainan, but I have 
no information concerning it. Pilger, т the * PAlanzenreich,’ Taxaceze (1903) 
p- 92, does not mention it as native to China. 
Six species of Popocarpus are enumerated, but their identification is by no 
means certain. Two species are probably exclusively Chinese, viz., P. argo- 
tenia, Hance, and P. sutchuenensis, Franchet. The others are found also in 
Japan (three species), the Malay Peninsula, &с. Pilger mentions P. chinensis, 
of Blume, at р..98, but gives no locality. The same author refers P. argo- 
tenia to a separate genus. 
CUNNINGHAMIA SINENSIS is exclusively Chinese and Formosan. 
SCIADOPITYS is exclusively Japanese. 
Of Pinus no fewer than thirteen species are recorded from China. Of 
these at least seven, so far as at present known, are peculiar to that country. 
They are P. scipioniformis, Mast., P. yunnanensis, Franchet, P. Armandi, 
Franchet, P. Bungeana, Zuccarini, P. lenryi, Mast., P. densata, Mast., 
P. prominens, Mast. The remaining Chinese species are natives also of Japan, 
Korea, and Manchuria. P. yunnanensis is allied to Р. khasya, from the 
Himalaya, to a species collected in Manipur by Sir George Watt, as well as 
to P. insularis from the Philippines *. Five species in all are recorded from 
Japan and Loo Choo (not including varieties). 
PicEA, Link, is exceptionally well represented in China, there being no 
fewer than fourteen species recorded, of which nine are endemic. One species 
belongs to the flat-leaved section, of which the Japanese P. ajanensis forms 
one member, P. sitchensis, from N.W. America, another, whilst S.E. Europe 
has its representative in P. Omorica. Other Chinese Spruces with four-sided 
leaves occur on the mountains of Western China, Sze-Chuan, Yunnan, and 
especially on the mountains by the Tibet border ; such are Р. Watsoniana, in 
addition to P. purpurea and asperata. From Japan only five species have 
been recorded, P. polita being the only peculiar species. 
It would thus seem that Western China was an important centre of distri- 
bution for species of Pinus and Picea, and to a less extent for species of Abies.
