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.

Key to Cupressaceae
Large shrub, 1- or multi-trunked tree, often pyramidal in youth; monoecious. Stem: young shoots or branches generally cylindric (sometimes ± 4-angled or flat), generally in 3-dimensional clusters. Leaf: opposite, 4-ranked, of 1 kind, scale-like, closely appressed, overlapping. Pollen cone: terminal, 2–6.5 mm, 1.3–3 mm diam, generally yellow. Seed cone: 10–50 mm, woody, ± spheric to widely cylindric, maturing 2nd year, generally closed and attached beyond maturity (> 2 years); scales (4)6–12, peltate, abutting, shield- or wedge-shaped, projection generally > 1 mm especially 1st year, pointed, base level with or rising from edge. Seed: 60–150 per cone, flat, wings generally 2, vestigial; cotyledons generally 3–5.Key to Hesperocyparis
