CONIFERS IN CHINA AND NEIGHBOURING COUNTRIES. 201 
East Tibetan border are included in the columns relating to Western and 
South-Western China. Other indications point to an affinity between the 
species of Northern Tibet and Northern China. 
The following remarks have reference to individual genera and species. 
The Ілвосерктв was at first thought to be confined to Formosa, but it has 
since been found in Yunnan. Other species oecur in New Zealand, the 
Chilian Andes, and N.W. America, but none has, so far, been detected in 
Japan. The genus is known to occur in the Cretaceous beds and in the 
Tertiary strata (Zeiller). 
Тноул is represented by the widely-spread T. orientalis and by a species, 
T. sutehuenensis, found on the mountains of Sze-Chuan, and closely allied to 
the N.W. American T. plicata, Donn, and to the Japanese T. japonica. 
Three species are named as oceurring in Japan, of. which two are peculiar to 
that country. 
Cupressus has one species peculiar to Formosa, whilst the elegant C. fune- 
bris is found also in Sikkim, but perhaps only in a cultivated state. C. sem- 
pervirens has been probably introduced. № is noteworthy that up to the 
present time no species of the section Chamweyparis has been met with in 
China, nor any Zetinospora (so called) such as are ко common in Japan. 
There are seven species of JUNIPERUS indicated, but none peculiar to China 
unless as a varietal form. The species occur in the Temperate Himalaya, 
Japan, Siberia, and even Europe. J. sinensis is remarkable for the frequency 
with which it retains in adult life the juvenile or Retinospora stage of foliage, 
even on the same branch with the adult leaves, Five species of Juniperus 
are known from Japan, of which J. nipponica is peculiar to that country. 
CRYPTOMERIA is probably only cultivated in China, but native to Japan. 
TAIWAINIA is a newly described genus from Formosa (see Hayata, in 
Journ. Linn. Soc., Bot. vol. xxxvii. (1906) p. 330, pl. 16). 
GLYPTOSTROBUs HETEROPHYLLUS is peculiar to Southern China. It is allied 
to but distinct from the Taxodium of Florida, of California, and of Mexico *. 
Of CEPHALOTAXUs there are six species, of which only one, C. Fortunei, 
is peculiar to China. Three species are found in Japan, of which one is 
peculiar to that country. С. Mannii has been discovered in the Eastern 
Himalayas as well as in Western China. 
Taxus is represented by T. baccata, which is well-nigh ubiquitous in the 
northern hemisphere. Whether there is one variable species or several 
specifically distinct is a question upon which botanists are not agreed f.
