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]

Genus Cupressus

Trees or large shrubs evergreen . Branchlets terete or quadrangular , in decussate arrays (or partially comblike in Cupressus macnabiana ). Leaves opposite in 4 ranks . Adult leaves appressed to divergent, scalelike, rhomboid , free portion of long-shoot leaves to 4 mm; abaxial gland present or absent. Pollen cones with 4--10 pairs of sporophylls, each sporophyll with 3--10 pollen sacs . Seed cones maturing in 1--2 years, generally persisting closed many years or until opened by fire, globose or oblong , 1--4 cm; scales persistent , 3--6 pairs, valvate , peltate, thick and woody. Seeds 5--20 per scale, lenticular or faceted , narrowly 2-winged; cotyledons 2--5. x = 11.

Species 10--26: warm north temperate regions .

The genus Cupressus in North America consists mainly of small, disjunct , relictual populations, many differing from related populations in color and size of leaves and seeds, activity of leaf glands , glaucousness of various parts, form of growth, and characteristics of bark . Disagreements on the number and rank of taxa reflect these variations . This treatment, with seven taxa, approaches the more conservative end of a spectrum; anywhere from 6 to 15 taxa---species, subspecies , and varieties---might be accepted in the flora . The taxonomy of the genus would benefit from detailed studies of variation in and among populations (cf. J. F. Goggans and C. E. Posey 1968).

The Mediterranean Cupressus sempervirens Linnaeus, usually with a fastigiate habit, is commonly cultivated in California, often away from dwellings, but it does not appear to have become naturalized . Other introduced Eurasian and Mexican species are clearly associated with cultivated landscapes.[2]
