Leaf: simple, cauline, alternate or opposite (either ± 4-ranked) or whorled in 3s (6-ranked), linear or scale-, awl- or needle-like (sometimes linear and awl-like on 1 plant, or on juvenile or injured plants), generally decurrent, covering young stems. Pollen cone: axillary or terminal. Seed cone: ± fleshy to generally woody, generally hard at maturity; scales opposite or whorled, peltate or not. Seed: 1–many per scale, angled or lateral winged, generally wind-dispersed.
