Its branchlets are more or less erect, up to 150 mm (5.9 in) long, the leaves reduced to erect to slightly spreading, scale-like teeth 0.4–0.8 mm (0.016–0.031 in) long, arranged in whorls of six or seven around the branchlets. The sections of branchlet between the leaf whorls (the "articles") are 5–12 mm (0.20–0.47 in) long, 0.7–1 mm (0.028–0.039 in) wide and have a waxy covering. Male flowers are arranged in spikes 10–40 mm (0.39–1.57 in) long, the anthers 0.7–0.8 mm (0.028–0.031 in) long. Female cones are cylindrical, on a peduncle 2–6 mm (0.079–0.236 in) long.
