 round foot-stalks ; they are flat, slightly linear, and tapering to

 rounded or obtuse on the apex, thin, and of a shining pale 

 brown colour. Bracteas very short, hatdly longer than the

 Seeds very small, with thin membraneous wings. 



A large tree, from 80 to 100 feet high, with the appearance 

 and habit of the Hemlock Spruce (Abies Canadensis), but with 

 the timber of a yellowish colour, and much valued by the 

 Japanese. 



It is found in the northern provinces of Japan, on the moun- 

 tains of " Matsu " and " Dewar," at an elevation of 6000 feet, 

 and on the sacred mountain, "Fusi-Yama," which is the highest 

 mountain in Japan (14,000 feet), and whose sides are covered 

 with dense pine forests, chiefly composed of this kind, to an 

 elevation of 8000 or 9000 Feet.
