Pollen cones terminal or axillary , solitary, maturing and shed annually; microsporophylls 6-16, decussate or whorled , each bearing (2 or) 3-6(-9) pollen sacs ; pollen wingless. Seed cones usually terminal, solitary, globose , ovoid , or oblong , dehiscent or indehiscent when mature in 1st or 2nd(or 3rd) year; cone scales developing after ovules originate in bract axils; bracts almost completely enveloped by cone scales, free only at apex; ovules 1-numerous per bract axil, erect ; cone scales of mature cones 3-16, flat or peltate, woody, leathery, or succulent, 1-20-seeded. Seeds winged or not; wings derived from seed coat . Cotyledons usually 2, rarely 3-6. Germination epigeal.

Nineteen genera and ca. 125 species: worldwide; eight genera (one introduced ) and 46 species (16 endemic, 13 introduced) in China.[1]

Notes

Publishing author : Hook. Publication : Hooker's Icones Plantarum 6 1843 (Jul. 1843)

Was formerly included under the family Taxodiaceae. The Taxodiaceae is now merged with Cupressaceae (see Farjon 2001).

This taxon is considered by Australian botanists to be an F1 hybrid between the two other species in this genus (all endemic in Tasmania); however, published evidence for this assertion is considered to be inconclusive and the species is maintained in Farjon (2005).[2].
