PEACTICAL FORESTRT. 



south of San Francisco. A rapid-growing tree, with a beauti- 

 ful fresh green fohage, but tender, except in our Southern 

 States. 



P. Lambertianaj Dougl. — Lambert's Pine, Sugar Pine. — Leaves 

 in fives, three to four inches long, from short deciduous sheaths, 

 with five or six lines of stomata on each side. Cones twelve to 

 eighteen inches long, and three or fom* in diameter, gradually 

 tapering to a point on peduncles three inches in length, pendu- 

 lous when mature, and of a brown color, destitute of resin. 

 Scales loosely imbricated, rounded above, without spine or 

 prickle. Seeds oval, nearly a half inch long, kernel sweet ; 

 wing almost twice as long as the seed, of a dark color. A very 

 large tree, one hundred to three hundred feet high, and ten to 

 twenty feet in diameter, with branches in whorls, bark smooth 

 and Hght-colored, except on the stem and larger branches. 

 Wood white, soft, resembling that of the White Pine, but a lit- 

 tle coarser-grained. More or less abundant throughout CaU- 

 fomia and northward to the Columbia River, on both slopes of 

 the Sierra Nevada, and at elevations of from three to eight 

 thousand feet. The exudations from the partly burned trees 

 acquires a sweetish taste, whence the name of "Sugar Pine." 

 A valuable forest tree, and seems to be as hardy in my grounds 

 as the common White Pine, which it very much resembles 

 while young, but when well estabhshed, grows far more rapidly, 

 becoming rather tall and naked in appearance, unless the lead- 

 ing shoots are headed back. 



P. mitiSj Michx. — Yellow Pine, Short-Leaved Pine. — Leaves in 

 twos, three to five inches long, with long sheath, slender, some- 

 what channelled, and of a dark green color. Cones oval or ob- 

 long, about two inches long, usually solitary, with a short, 

 incurved spine on each scale. Seed very small, with a reddish 

 wing. A tree forty to fifty feet high, with stem one to two 

 feet in diameter. Wood yellow, hard, durable, and employed 

 for ship building, spars, masts, plank, etc. In New Jersey, and 

 southward to Florida, also in Missouri and Arkansas. 



P. monophylla, Torr. and Frem. — Fremont's Pine, Nut Pine. — 

 Leaves, one or two in a sheath, from one and a half to two and 

 a half inches long, when in pairs, flat on the inner side, single 

 ones round, very rigid, and sharp-pointed. Leaves on terminal 

 branchlets, often bluish, glaucous-green or silvery. Cones two 

 inches long, or a little more, nearly round, of a light brown 

 color, scale thick, recurved, without spines. Seed quite large,
