Sugar Pine 



most other conifers, it does not thrive in the smoky air of dense cities. The name 

 Weymouth pine was given to the tree in England, because it was planted by Lord 

 Weymouth in Wiltshire, early in the eighteenth centur}^; it is also called Soft pine 

 and Northern pine. 



^. WESTERN WHITE PINE Pinus monticola Douglas 



This pine very closely resembles the eastern white pine, and was regarded 

 as a variety of it by Nuttall, but its differences from that species appear to be 

 constant. It reaches a maximum height of about 50 meters, with a trunk sometimes 

 nearly 3 meters thick, and occurs from northern Montana to southern British 

 Columbia, southward to the mountains of south-central Cahfomia. 



The thick bark of old trees is fissured into nearly square plates; that of young 

 trees is gray, smooth, or nearly so. The young twigs are stout and brown-hair)-, 

 becoming smooth and reddish. The leaves are 5 in each sheath, stout and stiff, 

 bluish green, 10 cm. long or less, their 

 sheaths loose, i to 2 cm. long, early 

 falUng away. The staminate flowers 

 are numerous, borne on the sides of 

 shoots of the season, i cm. long or 

 less; the pistillate flowers are terminal 

 and stalked. The ripe cone s are 1.2 to 

 2.7 dm. long, and 4 to 5 cm. thick, thus 

 much larger than those of Pinus Strohus; 

 they are pendulous, pointed, and their 

 scales open to shed the seeds in the 

 summer or autumn of the second sea- 

 son; the cones fall away from the tree 

 in the foUowinjr winter or spring; the 

 scales, are slightly thickened near the tip, 

 otherwise thin, sJiort-pointed, without 

 any sp^nc or prickle; the seeds are about 

 2.5 cm. long, the thin wing Jiree or four 

 times ,as long as the oblofig bo^y. 



T' .r tree is of slower growth than its 

 eastern -rlative; its wood is nearly white, soft and easily worked, has a specific 

 gravity of about 0.39 and is used in construction work. It is also known as Silver 

 pine. Finger-cone pine. Mountain pine. Little Sugar pine and Soft pine.

3. SUGAR PINE Pinus Lambertiana Douglas 



This, the largest of all pines, inhabits mountain sides and canons, occurring 

 from Oregon southward through California to central Lower California. Toward 

 the northern limit of its range it sometimes attains a height of 70 meters or some-
