83 HARDY CONIFEROUS TREES. 



dainty and greenest of all pines, while it is probably the most 

 rapid in growth. The leaves, two in a sheath, are slender and 

 threadlike, of a bright, clear green, and 5 inches long ; while 

 the cones are the same length, 2j inches in diameter, and of a 

 shining chocolate colour. It is certainly unfortunate that so 

 noble and beautiful a tree has not been found generally hardy 

 in these islands, and that it is, in consequence, but seldom 

 planted except in the south and west. It also suffers from wind- 

 waving, the head of foliage being heavy and the root-spread 

 narrow. Too much coddling should be dispensed with in the 

 cultivation of Pifiiis insig7iis^ as, being apt to start early into 

 growth, it suffers from our prevalent frosts in early May. A 

 plantation composed entirely of the tree has done well on 

 cold, late soil, and where freely exposed, in Sussex. 



P. JefFreyi, Murray. {Synonym: P. deflexa^ 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 appearance between this species 

 and P. ponderosa, particularly in the arrangement and length 

 of branches ; but close examination will show that in the 

 P. Jeffreyi both leaves and cones are considerably longer. 

 It is quite hardy, free of growth, and succeeds well on lime- 

 stone or chalky formations. 



P- Koraiensis, Siebold and Zuccarini. Korea, Kamt- 

 chatka, 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, and 

 the leaves glossy green above, and averaging 4 inches in length. 

 Cones 5 inches long, almost of equal diameter^ 2\ 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.
