Shrub, tree, evergreen; monoecious. Stem: young crown conic; twig not grooved, resinous, generally persistent. Leaf: simple, generally alternate, sometimes in bundles or appearing ± 2-ranked, linear or awl-like; base decurrent, woody or not, persistent several years. Pollen cone: generally < 6 cm, not woody, deciduous. Seed cone: generally woody; bracts, scales generally persistent; scale not peltate, fused to or free from subtending bract. Seed: 2, on scale base adaxially.
10 genera, 193 species: generally northern hemisphere; many of great commercial value, supplying > 1/2 of world's timber. —Scientific Editors: Thomas J. Rosatti, Bruce G. Baldwin.

Key to Pinaceae
Stem: crown conic; young branches appearing whorled, drooping or not; bark thin, scaly; twig with persistent, peg-like, spreading, < 2 mm leaf bases, glabrous or hairy; bud conic to ovoid, resinous. Leaf: often crowded toward upper side of twigs, generally < 3 cm, sessile, ± 4-angled or flat, stiff, often strong-smelling when crushed. Seed cone: conspicuously terminal or not, pendent, 5–12 cm, maturing 1st year; stalk 0–1 cm; bract included, ± free from scale. Seed: wing terminal.Key to Picea
34 species: northern hemisphere. (Latin: pitch) Trunks, especially of Picea sitchensis, more flared or buttressed at base than other California conifers.
Stem: trunk < 66 m, < 5.1 m wide; branches ± drooping; twig glabrous. Leaf: 1–3 cm, rigid; adaxially ± flat, with 2 faint, ± white bands, abaxially rounded, darker green, with 2 faint, ± white bands or not; tip acute, sharp to touch. Seed cone: < 10 cm, oblong; scale ± papery, margin ± jagged; bract > 1/2 scale.
