Stem: young crown conic; twig not grooved, resinous, generally persistent
Leaves simple, generally alternate, sometimes in bundles or appearing ± 2-ranked, linear or awl-like; bases decurrent, sometimes woody, 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
