Description

Habit: Evergreen, generally dioecious tree up to 30 m tall with brown to grayish bark that flakes in long thin flakes and a pyramidal crown, with very thin twigs.

Leaves: opposite and decussate in compressed nodes, persistent, simple, 1-2 mm long, scale-like, ovate, with a broad and decurrent base, sometimes glaucous, with an abaxial resin gland, appressed to the short internodes in such a way that the stem can hardly be seen; young leaves (sometimes present also in old branches) are more elongate, almost acicular.

Male cones: solitary, terminal, 2-3 mm long, ovoid or ellipsoid, yellowish. Female cones: solitary, terminal, inconspicuous.

Mature female cones: 5-6 mm in diam., ± ovoid, erect, glaucous, bluish-brown, formed by ± fused fleshy seed scales that do not separate when they mature. Each cone bears 1-4 seeds.

Phenology

Female cones appear at the end of winter or beginning of spring and mature in autumn of the first year.
