134 CONIFEROUS TREES 



the cultivation of Pinus insignis, as, being apt to 

 start early into growth, it suffers from our prevalent 

 frosts in early May. A plantation composed en- 

 tirely of the tree has done well on cold, slate soil, 

 and where freely exposed, in Sussex. 



P. Jeffreyi, Greville. (Synonym : P. defiexa, 

 Torrey.) California. 1852. — A noble-growing tree, 

 with stiff, short branches, placed far apart, and 

 beautifully glaucous leaves, about 10 inches long, 

 arranged three in a sheath. The cones are of a 

 warm brown colour, 8 inches long, the bracts 

 closely packed, and each terminating in a blunt 

 spine. There is much general agreement in appear- 

 ance between this species and P. ponderosa, parti- 

 cularly in the arrangement and length of branches ; 

 but close examination will show that in the P. 

 Jeffreyi both leaves and cones, the latter in 

 particular, are considerably longer. It is quite 

 hardy, free of growth, and succeeds well on lime- 

 stone or chalky formations. 



P. KORAiENSis, Siehold et Zuccarini. Korea, 

 Kamtschatka, Japan. 1861. — This is a handsome 

 and compact-growing tree, that forms a neat lawn 

 or garden specimen in a short space of time. The 

 branches are dense and short, the leaves glossy 

 green above, and averaging 4 inches in length. 

 Cones 5 inches long, almost of equal diameter — 2 J 

 inches — throughout, and with the rich brown 

 scales turned well back at their points. For 

 ornamental grounds this species is well worth 

 cultivating, the beautiful foliage tint and neat 

 habit being special recommendations. In this 

 country it does well in not too heavy nor damp 

 yellow fibrous loam.
