PINUS.
The leaves are of two kinds, primary and secondary; the primary are thin, deciduous scales, in the axils of which the secondary leaf-buds stand; the inner scales of those leaf-buds form a loose, deciduous sheath which encloses the secondary or foliage leaves, which in our species are all minutely serrulate.
Pinus Strobus, L.
White Pine.
Habitat and Range.—In fertile soils; moist woodlands or dry uplands.
Newfoundland and Nova Scotia, through Quebec and Ontario, to Lake Winnipeg.
New England,—common, from the vicinity of the seacoast to altitudes of 2500 feet, forming extensive forests.
South along the mountains to Georgia, ascending to 2500 feet in the Adirondacks and to 4300 in North Carolina; west to Minnesota and Iowa.
Habit.—The tallest tree and the stateliest conifer of the New England forest, ordinarily from 50 to 80 feet high and 2-4 feet in diameter at the ground, but in northern New England, where patches of the primeval forest still remain, attaining a diameter of 3-7 feet and a height ranging from 100 to 150 feet, rising in sombre majesty far above its deciduous neighbors; trunk straight, tapering very gradually; branches nearly horizontal, wide-spreading, in young trees in whorls usually of five, the whorls becoming more or less indistinct in old trees; branchlets and season's shoots slender; head cone-shaped, broad at the base, clothed with soft, delicate, bluish-green foliage; roots running horizontally near the surface, taking firm hold in rocky situations, extremely durable when exposed.
Bark.—On trunks of old trees thick, shallow-channeled, broad-ridged; on stems of young trees and upon branches smooth, greenish; season's shoots at first rusty-scurfy or puberulent, in late autumn becoming smooth and light russet brown.
