glaucous branchlets of aromatic fragrance with thinner and greyish 

 leaves, the greater size of the fruit-cones with thin and recurved 

 spines to the scales, the larger nutlets and more numerous cotyledons 

 separate this pine from P. ponderosa [Engelmann, Sargent, Perry]. 



Pinus Ksempferi, Lambert. 



Chinese Larch, also called Golden Pine. North-Eastern China. 

 This is the handsomest of all the larches ; it forms a transit to the 

 cedars. Resists severe frost. It is of quick growth and attains a 

 height of 150 feet. The leaves, which are of a vivid green during 

 spring and summer, turn to a golden-yellow in autumn. The wood 

 is very hard and durable. 



Pinus Kasya, Royle. 



Kasya and also Burmah, from 2,000 to 7,000 feet. Closely 

 related to P. longifolia. Attains a height of 200 feet. Wood very 

 resinous, somewhat fibrous, rather close-grained, pale brown with 

 darker waving [Kurz]. The resin an article of commerce [Sir 

 Jos. Hooker]. 



Pinus KoraiensiS, Siebold and Zuccarini. 



Kamtschatka, China and, Japan. A handsome pine, often to 40 

 feet high, producing edible seeds. 



Pinus Lambertiana, Douglas.* 



Shake-, Giant- or Sugar-Pine. British Columbia and California, 

 mostly at great altitudes. A lofty tree, of rapid growth, upwards 

 of 300 feet high, with a straight stem attaining 60 feet in circum- 

 ference. It holds in most places pre-eminence in beauty and size, 

 over accompanying pines, and reaches an age of 600 years [Dr. 

 Yasey]. It thrives best in sandy soil, and produces a soft, pale, 

 straight-grained wood, which for inside work is esteemed above 

 any other pine-wood in California, and obtained in large quantities ; 

 it is especially used for shingles, flooring, and for finishing purposes 

 by joiners and carpenters. The tree yields an abundance of 

 remarkably clear and pure resin, which from trees partially burnt 

 is of sweet taste, and eaten by the natives. The cones may be 19 

 inches long ; the seeds are edible. This pine would come to per- 

 fection best in the humid regions of higher mountains. P. reflexa 

 (Engelmann) is an allied large species with smaller fruit, occurring 

 in Arizona. 



Pinus Laricio, Poiret * (P. maritima, Miller.) 



Corsican Pine. South-Europe, ascending to about 6,000 feet. 

 It attains a height of 150 feet. A splendid shelter-tree, particularly 

 for the coldest regions. One of the best pines to thrive in the southern 

 part of the Middle Island of New Zealand [Waugh]. It is also culti- 

 vated at Christiania. It will succeed on stiff clay as well as on sandy
