A variety (var. megalancocarpa Sarg.) occurs in eastern New Mexico and northern Arizona, with fruit sometimes ¾′ in diameter. A tree often 40° high with a single erect stem sometimes 3° in diameter.
5. [Juniperus flaccida] Schlecht. Juniper.
Leaves opposite, acuminate and long-pointed, spreading at the apex, glandular or eglandular on the back, light yellow-green, about ⅛′ long, turning cinnamon-red and dying on the branch; on vigorous young shoots ovate-lanceolate, sometimes ½′ long, with elongated rigid callous tips. Flowers: male slender, composed of 16—20 stamens, with ovate pointed connectives prominently keeled on the back; female with acute or acuminate spreading scales. Fruit subglobose, dull red-brown, more or less covered with a glaucous bloom, ⅓′—½′ in diameter, with a close firm skin and thick resinous flesh; seeds 4—12, pointed at apex, slightly ridged, often abortive and distorted, ⅛′—¼′ long, with 2 cotyledons.
A tree, occasionally 30° high, with gracefully spreading branches and long slender drooping branchlets, covered after the leaves fall with thin bright cinnamon-brown bark separating into thin loose papery scales; often a shrub. Bark about ½′ thick, reddish brown, separating into long narrow loosely attached scales.
Distribution. In the United States only on the slopes of the Chisos Mountains, in Brewster County, southern Texas; common in northeastern Mexico, growing at elevations of 6000°—8000° on the hills east of the Mexican table-lands.
Occasionally cultivated in the gardens of southern France and of Algeria.
6. [Juniperus pachyphlæa] Torr. Juniper. Checkered-bark Juniper.
Leaves appressed, acute and apiculate at apex, thickened, obscurely keeled and glandular on the back, bluish green, rather less than ⅛′ long; on vigorous shoots and young branchlets linear-lanceolate, tipped with slender elongated points, and pale blue-green like the young branchlets. Flowers opening in February and March: the male stout, ⅛′ long, with 10 or 12 stamens, their connectives broadly ovate, obscurely keeled on the back, short-pointed: scales of the female flower, ovate, acuminate, and spreading. Fruit ripening in the autumn of its second season, subglobose to short-oblong, irregularly tuberculate, ⅓′—½′ in diameter, usually marked with the short tips of the flower-scales, occasionally opening and discharging the seeds at the apex, dark red-brown, more or less covered with a glaucous bloom, especially during the first season and then occasionally bluish in color, with a thin skin closely investing the thick dry mealy flesh, and usually 4 seeds; seeds acute or obtusely pointed, conspicuously ridged and gibbous on the back, with a thick shell and 2 cotyledons.
