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 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]
