PINACEiE 331 



A native of S. Saghalien and N, and E. Yezo. In the eastern 

 part of the island it forms pure forests, but never becomes a very 

 large tree and is rare elsewhere. It was discovered in Saghalien 

 in 1861 by Glehn, who accompanied Schmidt on an expedition to 

 E. Asia, and was introduced by Maries for Messrs. Veitch in 1877, 

 but only small plants are known in cultivation in England. 



The economic uses of P. Glehni appear to be confined to the 

 local use of the timber. 



Under cultivation it grows more slowly than the common 

 spruce and is probably better adapted for high land than for low 

 elevations where the resting period is short.

Picea jezoensis, Carriere. (Fig. 72.) 

 Yezo or Hondo Spruce. 



Picea ajanensis, Fischer ; Abies Alcoquiana, Linclley (in part). 



A tree 100-150 ft. high and up to 20 ft. in girth in Japan, 

 assuming, when well developed, a pyramidal or spire-like habit, 

 the branches being more or less deflexed, with the ends upturned. 

 Bark grey, scaling off in circular plates, deeply and irregularly 

 fissured in old trees. Young shoots glabrous, shining, pale buff, 

 brown or reddish brown in the second year, becoming sHghtly 

 darker in their third season and eventually showing a greyish 

 tinge. Buds broadly conic, with ovate, resinous, shining scales. 

 Leaves crowded and overlapping on the upper part of the shoot, 

 those below spreading in two opposite ranks, curving upwards 

 and exposing the shoot ; thin, flattened, bevelled off at the apex 

 into a short point, sHghtly keeled on both surfaces ; ventral 

 surface silvery white with two broad bands of stomata ; dorsal 

 surface dark green. Cones crimson when young, leather-brown 

 when ripe, cylindrical, 2-3 in. long by 1 in. in diameter ; scales 

 narrowly oblong with toothed margins ; bracts minute, concealed. 

 Seed with a wing two or three times its length. 



This tree has a very wide distribution inN.E. Asia and Japan, 

 and is the only flat-leaved spruce of that region. It extends 

 from Ajan on the sea of Okhotsk through the coast districts of 

 Amurland to Corea and Manchuria, where it reaches its southern- 

 most limit. The finest trees are found in the moist forests of 

 Yezo, the northern island of Japan. 



P. jezoensis was introduced into cultivation in 1861 by J. G, 

 Veitch, and owing to a mixture of seed was subsequently distri- 

 buted under the names of P. ajanensis and P. Alcockiana. 



It may be distinguished from the other flat-leaved spruces 

 by the pale shoots and dark green leaves, which are crowded 

 on the uj)per side of the shoot, and bluish or silvery white on
