Leaves acicular or linear, solitary or fascicled, persistent, rarely decidous.Staminate and ovuliferous cones monoecious; staminate cones consisting of numerous scales, the staminate scale with 2 pollen sacs. Ovuliferous cones with numerous scales, spirally arranged, each scale with 2 anatropous ovules on the inner side. Mature cones woody. Seeds 2 to each scale, usually winged; embryo with 2-15 cotyledons.
    About 12 genera, and 200 species, in the northern hemisphere from the subarctic to subtropical zones and tropical mountains; the following six genera are native to Taiwan. Another two genera, Cedrus and Larix, plus many exotic species of Pinus are cultivated.

Leaves in 2 ranks, spreading, linear-lanceolate,flat,with 2 white stomatic bands beneath,and with 2 lateral resin ducts. Staminate cones pendent, ovoid to cylindric-oblong. Ovuliferous cones ovoid to oblong, consisting of numerous closely imbricate scales, each scale with 2 ovules. Mature cones large and erect, the scales falling off with the seeds. Seeds ovoid or oblong, with a large thin wing; embryo with 4-10 cotyledons.
    About 40 species in temperate regions of the northern hemisphere, generally mountain trees; one species occurs in Taiwan.
