These are a big coniferous tree personal within metal money diversity, by having between 220-250 mintage (based in taxonomic opinion) in Eleven genera, & a 2nd-largest (when Cupressaceae) around geographical range, observed in virtually all a Northern Hemisphere with the majority of the metal money within moderate climates however ranging from either subarctic to tropical. Of these mintage only crosses a equator in southeast Asia. Major centres of diversity come obtained in the mountains of sou'west China, central Japan, California and Mexico.

A female cones are large & normally woody, 2-60 cm yearn, sustaining many spirally-intended scales, & two winged seeds on each shell. A male cones come microscopic, Zero.Five-6 cm yearn, & fall shortly when pollenation; pollen dissemination is by wind. Seed diffusion is mostly by wind, however a select few mintage keep around big seeds by using decreased wings, & come dispersed by birds. A embryos come multi-cotyledonous, using Three-2 dozen cotyledons.

Classification
A Eleven genera come divided into foursome subfamilies, according to a cone, seed & leaf morphology:
