PINACE^ 343 



Var. alpestris, Henry, 

 Bark greyish white. Leaves |-| in. long, stout, very glaucous. 

 Cones 3-5 in. long, with scales rounded and entire on the upper 

 margin. 



Var. fennica, Henry. 



Leaves dark green ; cone scales with their upper margins 

 rounded and finely toothed. 



This species is distinguished from P. excelsa by its hairy 

 shoots and shorter leaves. The two species are apparently 

 connected by intermediate forms. 



It is the most widely distributed of the spruces, occurring over 

 a vast area in E. Europe and Asia, where the cUmatic conditions 

 are very severe. It is found in N. Scandinavia, Lapland, Finland, 

 N, and E. Russia, Siberia, Kamtschatka, and Manchuria, 

 occasionally forming extensive forests. 



We have no large trees of this spruce in England. Seedlings 

 were raised at Bayfordbury, Herts., in 1908, from Siberian seeds, 

 and small plants labelled P. obovata are occasionally seen in 

 collections. 



The uses are similar to those of P. excelsa, which see. 



It appears to require a longer resting period than is possible 

 in Britain.

Picea Omorika, Bolle. (Fig. 77.) 

 Servian Spruce. 



Pinus Omorika, Pancic. 



A tree with a remarkably slender trunk and a spire-like 

 crown, attaining in its native habitat a height of over 100 ft. and 

 a girth of only about 4 ft. Bark of trunk reddish brown, scaling 

 off in plate -hke layers. Branches short in proportion to the height 

 of the tree, the lower ones drooping but turning upwards at the 

 ends, the upper ones horizontal or ascending. Young shoots 

 light brown, hairy. Buds ovoid-conic, acute up to about J in. 

 long, with red-brown scales, the outermost scales ending in long 

 awl-shaped points. Leaves more or less horizontally arranged, 

 those on the lower side of the shoot curving downwards, those 

 on the upper side of the shoot overlapping and pointing forwards, 

 flattened, |-f in. long with a short, acute or obtuse tip, convex 

 and shining on the dorsal surface with two white lines of stomata 

 separated by a prominent midrib on the ventral surface. Cones 

 ovoid-conic, about l|-2 in. long, bluish-black when young, dark 

 brown when ripe, horizontal or pendulous, with roundish, convex 

 scales. Seed small, about ^ in. long, wing | in. long.
