Description

Family Cupressaceae

Trees or shrubs evergreen , monoecious or dioecious. Leaves decussate or in whorls of 3, scalelike and then often dimorphic with flattened facial leaves and keeled lateral leaves, or needlelike particularly in juvenile plants , often with an abaxial resin gland . 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]

Adult leaves dimorphic , appressed , overlapping, scalelike, lateral leaves overlapping facial leaves, free portion of long-shoot leaves to ca. 3 mm; abaxial glands present. Pollen cones with 6--8 pairs of sporophylls, each sporophyll with 4 pollen sacs . Seed cones maturing and opening first year, ellipsoid , 17--30 mm; scales persistent , (2--) 3 pairs, oblong and basifixed , thin and woody; proximal pair reduced, sterile , often reflexed or lacking; median pair fertile ; distal pair connate , sterile. Seeds 2 per scale, lenticular , unequally 2-winged; cotyledons 2. x = 11.
