A Japanese species formerly confounded with P. Massoniana 
(p. 611) and P. densiflora, but distinct from both in foliage, leaf- 
bud,and cones. The leaves are boat-shaped in section with a thick 
hypoderm. The cells of the mesophyll have infolded walls. The 
resin-canals encircled by a sheath of stereome traverse the centre

cells. The meristele is elliptic in section, and the two branches 
of the fibro-vascular bundle are separated by stereome-cells. 
Androgynous cones occasionally occur. See Gard. Chron. June 30, 
1883, p. 825; also Tokyo Botanical Magazine, June 10, 1892,

The Abbé David, in a note attached to a specimen of this 
species, n. 2890, in the Paris herbarium, speaks of this as a large 
tree with verticillate ascending branches, occurring on the lofty 
mountains of Western Ourato.
