Description

[ Back to top ]

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 Juniperus

Shrubs or trees evergreen . Branchlets terete , 3--6 angled , variously oriented, but not in flattened sprays . Leaves opposite in 4 ranks or in whorls of 3. Adult leaves closely appressed to divergent, scalelike to subulate , free portion to ca. 10 mm (to ca. 15 mm in Juniperus communis ) ; abaxial gland visible or not, elongate to hemispheric ( J. ashei ), sometimes exuding white crystalline deposit. Pollen cones with 3--7 pairs or trios of sporophylls, each sporophyll with 2--8 pollen sacs . Seed cones maturing in 1 or 2 years, globose to ovoid and berrylike, 3--20 mm, remaining closed , usually glaucous; scales persistent , 1--3 pairs, peltate, tightly coalesced , thick and fleshy or fibrous to obscurely woody. Seeds 1--3 per scale, round to faceted , wingless; cotyledons 2--6. x = 11.

Species ca. 60: primarily Northern Hemisphere, 1 in e Africa.

Juniperus is the only dioecious (sometimes monoecious) genus of Cupressaceae in the flora . Cones, generally terminal , are axillary in J. communis.

Numerous cultivars of Juniperus species are widely used for landscaping. Mutants , or "sports," affecting plant habit and foliage are present in all species and are likely related to single-gene mutations . Many have been given formal names or incorrectly ascribed to hybridization. Gymnocarpy (bare seeds protruding from the cone), caused by insect larvae (T. A. Zanoni 1978), is occasionally found in most junipers, particularly in the southwestern United States. Specimens with such aberrations may be almost impossible to identify without chemical data.[2]
