Chapter 3 PINACE .

Trees, with narrow or scale-like generally persistent clustered or alternate leaves and usually scaly buds. Flowers appearing in early spring, mostly surrounded at the base by an involucre of the more or less enlarged scales of the buds, unisexual, mon?cious (di?cious in Juniperus), the male consisting of numerous 2-celled anthers, the female of scales bearing on their inner face 2 or several ovules, and becoming at maturity a woody cone or rarely a berry. Seeds with or without wings; seed-coat of 2 layers; embryo axile in copious albumen; cotyledons 2 or several.

Pinus is widely distributed through the northern hemisphere from the Arctic Circle to the West Indies, the mountains of Central America, the Canary Islands, northern Africa, the Philippine Islands, and Sumatra. About sixty-six species are recognized. Of exotic species the so-called Scotch Pine, Pinus sylvestris L., of Europe and Asia, the Swiss Stone Pine, Pinus cembra L., and the Austrian Pine and other forms of Pinus nigra Arnold, from central and southern Europe, are often planted in the northeastern states, and Pinus Pinaster Ait., of the coast region of western France and the Mediterranean Basin is successfully cultivated in central and southern California. Pinus is the classical name of the Pine-tree.

Leaves linear, sessile, on young plants and on lower sterile branches flattened and mostly grooved on the upper side, or in one species 4-sided, rounded and usually emarginate at apex, appearing 2-ranked by a twist near their base or occasionally spreading from all sides of the branch, only rarely stomatiferous above, on upper fertile branches and leading shoots usually crowded, more or less erect, often incurved or falcate, thick, convex on the upper side, or quadrangular in some species and then obtuse, or acute at apex and frequently stomatiferous on all sides; persistent usually for eight or ten years, in falling leaving small circular scars. Flowers axillary, from buds formed the previous season on branchlets of the year, surrounded at the base by conspicuous involucres of enlarged bud-scales, the male very abundant on the lower side of branches above the middle of the tree, oval or oblong-cylindric with yellow or scarlet anthers surmounted by short knob-like projections, the female usually on the upper side only of the topmost branches, or in some species scattered also over the upper half of the tree, erect, globose, ovoid or oblong, their scales imbricated in many series, obovate, rounded above, cuneate below, much shorter than their acute or dilated mucronate bracts. Fruit an erect ovoid or oblong-cylindric cone, its scales closely imbricated, thin, incurved at the broad apex and generally narrowed below into long stipes, decreasing in size and sterile toward the ends of the cone, falling at maturity with their bracts and seeds from the stout tapering axis of the cone long-persistent on the branch. Seeds furnished with large conspicuous resin-vesicles, ovoid or oblong, acute at base, covered on the upper side and infolded below on the lower side by the base of their thin wing abruptly enlarged at the oblique apex; seed-coat thin, of 2 layers, the outer thick, coriaceous, the inner membranaceous; cotyledons 4-10, much shorter than the inferior radicle.

Abies is widely distributed in the New World from Labrador and the valley of the Athabasca River to the mountains of North Carolina, and from Alaska through the Pacific and Rocky Mountain regions to the highlands of Guatemala, and in the Old World from Siberia and the mountains of central Europe to southern Japan, central China, Formosa, the Himalayas, Asia Minor, and the highlands of northern Africa. Thirty-three species are now recognized. Several exotic species are cultivated in the northern and eastern states; of these the best known and most successful as ornamental trees are Abies Nordmanniana, Spach, of the Caucasus, Abies cilicica Carr., of Asia Minor, Abies cephalonica Loud., a native of Cephalonia, Abies Veitchii Lindl., and Abies homolepis S. & Z., of Japan, and Abies pinsapo, Boiss., of the Spanish Sierra Nevada.

Abies is the classical name of the Fir-tree.

Fruit an ovoid or short-oblong pendulous cone maturing during the first or second season, persistent after the escape of the seeds, its scales formed by the enlargement of the united flower and ovuliferous scales, becoming woody, bearing large deciduous resin-glands, gradually enlarged upward and widening at the apex into a narrow thickened oblong disk transversely depressed through the middle and sometimes tipped with a small point. Seeds 5-7 under each scale, oblong-ovoid, compressed; seed-coat membranaceous, produced into broad thin lateral wings; cotyledons 4-6, longer than the inferior radicle.

Sequoia, widely scattered with several species over the northern hemisphere during the cretaceous and tertiary epochs, is now confined to the coast of Oregon and California and the mountains of California, where two species exist.

The name of the genus is formed from Sequoiah, the inventor of the Cherokee alphabet.
