bundle unbranched. There are five rows of stomata on the two 
sides of the leaf and none on the dorsum. The cells of the 
mesophyll have plicated walls. Cotyledons 8-12. 
It extends, with few interruptions, along the Himalayas from 
Afghanistan to Bhutan, and its value as a timber tree is well

A Pine of the Cembra section, native of Corea, Central China, 
Japan P, and Kamtschatka. It has been confounded in books 
and herbaria with P. parviflora; butthe resin-canals are median, 
and the cones are more elongate, with the scales tapering towards 
the ends and often recurved. The herbaceous shoots are some- 
what woolly, devoid of leaves at the base. The leaves are three- 
sided, with no stomata on the dorsum, with little or no hypoderm, 
the meristele roundish or obscurely triangular, the endoderm-layer 
of about 20 cells, and the fibro-vascular bundle unbranched. 
The cells of the mesophyll are plicate. 
The male flowers are in clusters, each ovoid-oblong, about 
2 cent. long, pinkish violet ; anther-lobes not crested. The young 
female flowers are purple; the seeds wingless or nearly so. 
It has been lately introduced from West Hupeh by Wilson, 
no. 597! and is figured in the ‘ Gardeners’ Chronicle’ (1903), 1.

“This is a five-leaved Pine of the Cembra section, with smooth 
bark, slender leaves, and oblong cones. It differs from P. korat- 
ensis in the cones being broader in proportion to their length 
and in the cone-scales not being reflexed at the tips. From 
P. parviflora it differs in its longer leaves, larger cones, and 
wingless seeds. 
“The branches are smooth, greyish in colour, the pale green 
leaves in tufts of five, with a very short deciduous sheath. Each 
leaf is about 14 to 15 cent. in length, three-sided, serrulate, tri- 
angular in section, with the resin-canals median. There are no 
stomata on the dorsum. The section of the central vascular 
cylinder or meristele is circular, and the fibro-vascular bundle is 
unbranched. The endoderm-cells are about 26in number. The
