Description

A prostate plant or a small broadly conical shrub to 3 m. tall. Plant spreads by underground stolons. Branchlets finely divided, twisted into long branchlets. Juvenile leaves light silvery-green, 8-15 mm. long, needle-like, persistent. Adult leaves scalelike, in whorls of 3, up to 10 mm. long, dark green. Male cones ovoid, on a peduncle 4 mm. long, 4-6 mm long, 2-3 mm diameter, with 20 acuminate scales with a dorsal crest. Female cones yellowish-brown to glaucous-brown, ovoid-conical, distinctly longer than broad, acute, 20-35 mm long, 15-25 mm diameter, often subtended at the base by juvenile leaves to 1 cm. long; the 6 scales acute, erect, spreading when open, distinctly hooked at tip. Seeds variable, dark brown, 9-12 mm. long, 9-13 mm. wide, wing 2-5 mm. wide, hilium 3-5 mm. long and white. Cotyledons 2, light green, 15-18 mm. long by 3-3.5 mm. wide, apex bluntly acute, stem to 2 mm. thick (Silba 1986, Hill 1998).
