Leaves acute, rounded and minutely glandular-pitted or eglandular on the back, light blue-green, about 1/16′ long. Fruit on stout stems ¼′—⅓′ in length, subglobose to short-oblong, ¾′—1¼′ in diameter, puberulous especially along the margins of the six or eight scales, with prominent flattened or conic acute often incurved bosses; seeds about 70 under each scale, short-oblong, nearly square, light chestnut-brown up to ¼′ in length, with a narrow wing.
A tree in California sometimes 20°—25° in height, with a short slender or on exposed mountain slopes a trunk occasionally 2° or 3° in diameter, few short spreading or ascending branches forming an open head, and light red-brown lustrous branchlets becoming purplish. Bark smooth, lustrous, without resin or fibres, mahogany brown, the thin scales in falling leaving pale marks.
Distribution. San Diego County, California, rare and local; valley of the San Luis Rey River between Valley Centre and Pala; at altitudes between 1100° and 4000° in the gulches and on the summit of Mt. Tecate on the border between the United States and Lower California; on a mountain below Descanso and Pine Valley; in Cedar Cañon between El-nido and Dulzura; in Lower California on San Pedro Mártir Mountain and Guadaloupe Island. The insular form is a larger tree often with larger gland-pits on the leaves, and now often cultivated in California, western Europe, and in other countries with temperate climates.
6. [Cupressus arizonica] Greene. Cypress.
Leaves obtusely pointed, rounded, eglandular or rarely glandular-pitted on the back, pale green, 1/16′ long, dying and turning red-brown in their second season, generally falling four years later. Flowers: male oblong, obtuse, their 6 or 8 stamens with broadly ovate acute yellow connectives slightly erose on the margins: female not seen. Fruit on stout pedicels ¼′—½′ in length, subglobose, rather longer than broad, wrinkled, dark red-brown and covered with a glaucous bloom, the six or eight scales with stout flattened incurved prominent bosses; seeds oblong to nearly triangular, dark red-brown, 1/16′—⅛′ long with a thin narrow wing.
A conical tree 40°—70° high with a trunk 2°—4° in diameter, and stout spreading branches covered with bark separating into thin plates, leaving a smooth red surface, and branchlets dark gray after the leaves fall. Bark on young trunks separating into large irregular curling thin scales, on old trees becoming dark red-brown and fibrous.
Distribution. Mountains above Clifton, Greenlee County, eastern Arizona; on the San Francisco Mountains, Socorro County, and San Luis Mountains, Grant County, western New Mexico; and in Chihuahua. Passing into
