104 HARDY CONIFEROUS TREES. 



ance and smooth ashen-grey bark. The leaves, arranged five 

 in a sheath, are nearly 5 inches long, very slender, and of a 

 pleasing, soft, silvery-green tint ; while the cones are from 6 

 inches to fully 8 inches in length, usually bent or curved, and 

 when growing exude resin freely. In some of the woods at 

 Woburn Abbey, the Weymouth pine has reproduced itself 

 from seed in large numbers, and these seedlings have been 

 taken advantage of and utilised as forest trees. 



P. Strobus nana grows to 5 feet in height, and is of 

 dense globular habit when young, but apt to lose the lower 

 branches with advancing years, and then assumes a less com- 

 pact and pleasing appearance. The branches and branchlets 

 are short and slender, and the leaves 2 inches long, and pro- 

 duced thickly at the branch extremities. 



P. Thunbergfii, Parlatore. (^Synonyms : — P. silves- 

 tris, Thunberg ; P. Pinaster, Loudon ; P. rubra, Siebold ; P. 

 Massoniana, Siebold and Zuccarini.) Japan. — This is a rare 

 tree in Britain, though in Cornwall and other warm maritime 

 places, as also at Kew, good examples may be seen. The 

 leaves are 5 inches long, rather tortuous, and deep green in 

 colour. The cones, both in shape and size, resemble those of 

 our common larch. All the specimens I have seen of this 

 tree differ from P. Massoniana, with which it is sometimes 

 included. P. TJiunbergii aurea is a desirable variety. 



P. tuberculata, Gordon. Oregon and west side of 

 Californian coast ranges. — Amongst hardy or tolerably 

 hardy species the present should be included, for in many 

 parts of the country it has succeeded admirably, though in 

 others it has failed to become established. Usually it forms a 

 specimen of fully 20 feet in height, with a well rounded and 

 thickly branched head, the lower portion of the trunk being 

 destitute of branches, these after about twelve years' growth 

 gradually, with a portion of the foliage, giving way. The 

 leaves are bright green, nearly 6 inches in length, and the cones 5 

 inches long by 2 inches diameter at thickest part. The cones 

 are produced in clusters, but sometimes straggling singly on 

 both stem and branches, and persist for many years, those on
