Leaves spreading nearly at right angles to the branchlets, ⅓′—½′ long, about 1/32′ wide, turning during winter a deep rich bronze color on the lower surface, persistent for many years. Flowers: male composed of 5 or 6 whorls each of 3 stamens, with broadly ovate acute and short-pointed connectives, bearing at the very base 3 or 4 globose anther-cells; female surrounded by 5 or 6 whorls of ternate leaf-like scales, composed of 3 slightly spreading ovules abruptly enlarged and open at the apex, with 3 minute obtuse fleshy scales below and alternate with them. Fruit maturing in the third season, subglobose or short-oblong, about ¼′ in diameter, with soft mealy resinous sweet flesh and 1—3 seeds; often persistent on the branches one or two years after ripening; seeds ovoid, acute, irregularly angled or flattened, deeply penetrated by numerous prominent thin-walled resin-glands, about ⅛′ long, the outer coat thick and bony, the inner membranaceous.
In America only occasionally tree-like and 10°—20° tall, with a short eccentric irregularly lobed trunk rarely a foot in diameter, erect branches forming an irregular open head, slender branchlets, smooth, lustrous, and conspicuously 3-angled between the short nodes during their first and second years, light yellow tinged with red, gradually growing darker, their dark red-brown bark separating in the third season into small thin scales, and ovoid acute buds about ⅛′ long and loosely covered with scale-like leaves; more often a shrub, with many short slender stems prostrate at the base and turning upward and forming a broad mass sometimes 20° across and 3° or 4° high (var. depressa Pursh.); at high elevations and in the extreme north prostrate, with long decumbent stems and shorter and more crowded leaves (var. montana Ait.) passing into the var. Jackii Rehdr. with long trailing branches and broader incurved leaves. Bark about 1/16′ thick, dark reddish brown, separating irregularly into many loose papery persistent scales. Wood hard, close-grained, very durable in contact with the soil, light brown, with pale sapwood. In northern Europe the sweet aromatic fruit of this tree is used in large quantities to impart its peculiar flavor to gin; occasionally employed in medicine.
Distribution. Occasionally arborescent in New England, eastern Pennsylvania, and on the high mountains of North Carolina; the var. depressa, common in poor rocky soil, Newfoundland to southern New England, and to the shores of the Great Lakes and northwestward; the var. montana from the coast of Greenland to northern New England, on the high Appalachian Mountains, North Carolina, and to northern Nebraska, along the Rocky Mountains from Alberta to western Texas, and on the Pacific coast from Alaska, southward along mountain ranges to the high Sierras of central California, extending eastward to the mountains of eastern Washington and Oregon, and on the high peaks of northern Arizona up to altitudes of 10,000°—11,500° (P. Lowell); the var. Jackii on the coast mountains from northern California to Vancouver Island; in the Old World widely distributed in many forms through all the northern hemisphere from arctic Asia and Europe to Japan, the Himalayas and the mountains of the Mediterranean Basin.
Often planted, especially in several of its pyramidal and dwarf forms, in the eastern United States and in the countries of western, central, and northern Europe.
2. [Juniperus Pinchotii] Sudw.
Leaves ternate, obtusely pointed, rounded and glandular-pitted on the back, 1/16′ long, dark yellow-green, turning light red-brown before falling; on vigorous shoots and seedling plants linear-lanceolate, thin, acuminate, eglandular, ¼′—⅓′ in length. Fruit ripening in one season, subglobose, bright red, ¼′ in diameter, with a thin skin and thick dry mealy resinous flesh and 1 seed; seed ovoid, bluntly pointed, deeply grooved, irregularly marked by the usually two-lobed hilum, ⅙′—¼′ long and 2 cotyledons.
A tree rarely 20 feet high, with a trunk 1 foot in diameter, stout wide-spreading branches forming an open irregular head and thick branchlets covered with dark gray-brown scaly bark, their ultimate divisions about 1/12′ in diameter; more often a shrub with several stems 1° to 12° tall. Bark thin, light brown, separating into long narrow persistent scales.
Distribution. Dry rocky slopes and the rocky sides of cañons, Panhandle of western Texas (Armstrong, Potter and Hartley Counties), and in Hardaman, Garza, Tom Green, Kemble, Valverde and Menard Counties; on Comanche Peak near Granbury, Hood County, Texas; in central and on the mountains of southern Arizona.
