82 HARDY CONIFEROUS TREES. 



P. Cembra,^ Linnaeus. Mountains of Central Europe, 

 Siberia. — This is a beautiful tree of neat growth, perfect 

 hardihood, and one that succeeds in many soils and situations. 

 There is a good deal of difference in the habit of various trees, 

 some being of upright growth and others more spreading,but the 

 usual type has the branches short in proportion to the height 

 somewhat tortuous,and decidedly erect and appressed. Usually 

 the leaves are five in a sheath, though sometimes four or six, 

 stout and flexible, serrated at the margins, and nearly 3 inches 

 long. Cones erect, of a beautiful bluish purple when of full 

 growth but before becoming ripe, and varying much in size, but 

 usually from 3 inches to 4 inches long, and about half that in 

 diameter, and with large wingless seeds. The most suitable soil 

 is that of a deep rich loam on a porous subsoil, but the tree is in- 

 different in that respect, for many fine specimens are to be found 

 on gravelly and sandy loam if not too hot and dry, as also on 

 chalky soils. Although British-grown timber is excellent in 

 quality, yet the rate of growth of the tree is too slow in this coun- 

 try for it to be used at all extensively for afforesting purposes. 



P. Cennbra pumila (Kamtchatka and the Kurile 

 Islands) is of small, compact, and neat growth, as usually seen 

 in cultivation, and the foliage is more silvery than is the case 

 with the species generally. The leaves are thin, i| inches 

 long, and the cones remarkably neat, being ij inches long by 

 I inch diameter. For confined spaces or rock-work this variety 

 is to be recommended, the height rarely exceeding 4 feet. 



P. cembroides, Zuccarini. {Synonyms : — P. Llaveana^ 

 Schiede and Deppe ex Parlatore ; P. osteosperma, Engelmann.) 

 Arizona. 1846. — This is of no great value for the purpose of 

 ornament, and less so for the value of the timber it produces. 

 As generally seen, it is of contorted and dwarfed appearance, 

 with irregularly arranged branches, well furnished with nearly 

 erect-growing, stiffish leaves, each fully i^ inches long, and 

 bright green of colour. The cones are small, neat, and dull 

 brown, each about i| inches long.
