P. parviflora, Lambert.—Japanese White Pine. 
Although not an imposing tree as seen in, the British Isles, 
this, the ‘‘ himeko-matsu ’’ of Japan, is said to be the most 
conspicuous feature in certain parts of that country, where, 
according to ‘‘ Forestry in Japan,’’ it spreads over the mountain 
ranges of Iwashiro, starting from an elevation of 1600 metres, 
along the borders of Kozuke and Echigo, and in Tsushima and 
Shiribeshi, Hokkaido. A form of the tree is also found in the 
Kurjle Islands. It belongs to the group ‘bearing leaves in 
bundles of five, and is usually met with 50-60 ft. high, although 
it sometimes attains a height of 100 ft. The wood is considered 
to be less useful than that of other Japanese pines, and is only 
used locally. As heavy coning commences very early in life 
growth is often checked, and trees in this country usually present 
a stunted appearance and are not very ornamental. — 
P. Thunbergii, Parlatore.—Japanese Black Pine. 
Next to P. densiflora this is the most important pine in Japan, 
where it grows 100-120 ft. high with a girth of 12-20 ft. The 
leaves are in pairs 3-4 in. long, and the cones, which are 
2-21 in. long are often produced in large clusters, 40-65 cones 
having been counted in individual clusters. Moreover, male an 
emale flowers may sometimes be found in the same cluster. In 
Japan it is known by the name of “ kuro-matsu,”’ and is planted 
as a wind-break in addition to being useful for reclaiming sand 
dunes and other purposes. The wood is used for many purposes, 
but is said to be inferior to that of P. densiflora. The tree grows 
well in the British Isles, and has been used in the Channel 
Islands and in Ireland as a wind-break near the sea.
