Characteristics

Trees evergreen, monoecious; branchlets arranged in a plane, spreading or ascending, flattened, prominently jointed. Leaves decussate, almost in whorls of 4, scalelike, base decurrent, dimorphic along branchlets: facial pairs flattened; lateral pairs boat-shaped, usually less than 4 mm, overlapping facial pairs, without conspicuous, white stomatal bands abaxially. Pollen cones terminal, solitary; microsporophylls 10-16, each with 2-5 pendulous pollen sacs. Seed cones terminal, solitary, oblong or ellipsoid-cylindric, dehiscent when mature in 1st year; cone scales 6, decussate, flat, only middle pair fertile, each fertile scale bearing 1 or 2 seeds; free bract apex a short mucro. Seeds with 2 subapical, unequal wings. Cotyledons 2.
More
Trees evergreen, large. Branchlets flattened, in fan-shaped flattened sprays. Leaves opposite in 4 ranks (although apparently in whorls of 4). Adult leaves dimorphic, appressed, overlapping, scalelike, lateral leaves overlapping facial leaves, free portion of long-shoot leaves to ca. 3 mm; abaxial glands present. Pollen cones with 6--8 pairs of sporophylls, each sporophyll with 4 pollen sacs. Seed cones maturing and opening first year, ellipsoid, 17--30 mm; scales persistent, (2--)3 pairs, oblong and basifixed, thin and woody; proximal pair reduced, sterile, often reflexed or lacking; median pair fertile; distal pair connate, sterile.
