Description
Family Pinaceae
Trees
or rarely shrubs
, evergreen
or deciduous, monoecious. Branchlets
often dimorphic
: long branchlets with clearly spirally arranged
, sometimes scalelike leaves; short branchlets often reduced to slow growing lateral
spurs bearing dense clusters
of leaves at apex. Leaves solitary or in bundles of (1 or) 2-5(-8) when basally subtended by a leaf sheath
; leaf blade linear
or needlelike, not decurrent. Cones unisexual
. Pollen cones solitary or clustered, with numerous
spirally arranged microsporophylls
; microsporophyll with 2 microsporangia; pollen usually 2-saccate (nonsaccate in Cedrus, Larix, Pseudotsuga, and most species of Tsuga) . Seed cones erect
or pendulous, maturing in 1st, 2nd, or occasionally 3rd year, dehiscent
or occasionally indehiscent, with many spirally arranged ovulate
scales
and bracts; ovulate scales usually smaller than bracts at pollination, with 2 upright ovules adaxially, free
or only basally adnate
with bracts, maturing into seed scales. Seed scales appressed
, woody or leathery, variable in shape
and size, with 2 seeds adaxially, persistent
or deciduous after cone maturity. Bracts free or adnate basally with seed scales, well developed or rudimentary
, exserted or included
. Seeds terminally winged
(except in some species of Pinus) . Cotyledons 2-18. Germination hypogeal or epigeal. 2n = 24* (almost always) .
Ten or eleven genera and ca.
235 species: N hemisphere; ten genera (two endemic) and 108 species (43 endemic, 24 introduced
) in China.
Species of the Pinaceae are among the most valuable and commercially important plants
in the world. Most species are trees, and are often excellent sources of lumber, wood
products, and resins; many are cultivated for afforestation
and as ornamentals
.[1]
Genus Pinus
Trees
or shrubs
aromatic
, evergreen
; crown usually conic when young, often rounded
or flat-topped with age. Bark
of older stems variously furrowed
and plated, plates
and/or ridges
layered
or scaly
. Branches usually in pseudowhorls; shoots
dimorphic
with long shoots and short shoots; short shoots borne in close spirals
from axils of scaly bracts and bearing fascicles of leaves (needles
) . Buds ovoid
to cylindric
, apex pointed
(blunt
), usually resinous
. Leaves dimorphic, spirally arranged
; foliage
leaves (needles) (1--) 2--5(--6) per fascicle, persisting 2--12 or more years, terete
or ± 2--3-angled and rounded on abaxial
surface, sessile, sheathed at base
by 12--15 overlapping scale leaves, these (at least firmer basal ones) persisting for life of fascicle or shed after first season
; resin canals 2 or more. Pollen cones in dense, spikelike cluster
around base of current
year's growth, mostly ovoid to cylindric-conic, tan to yellow, red, blue, or lavender. Seed cones maturing in 2(--3) years, shed early or variously persistent
, pendent to ± erect
, at maturity conic or cylindric, sessile or stalked
, shedding seed soon after maturity or variously serotinous (not opening upon maturity but much later) ; scales
persistent, woody or pliable, surface of exposed apical portion of each scale (apophysis) thickened, with umbo (exposed scale surface of young cone) represented by a scar
(sometimes apiculate
) or extended into a hook, spur, claw
, or prickle; bracts included
. Seeds winged
or wingless; cotyledons (3--) 6--10(--18) . x
=12.
Species ca.
100 (38 in the flora
with 37 native
and 1 widely naturalized
) : widespread in north temperate
and north tropical
(mountainous) regions, North America, Mexico, West Indies, Central America, Eurasia
(including 1 crossing equator in Sumatra), n Africa, Pacific Islands in Sumatra.
In many areas Pinus is a forest
dominant, either early successional and thus weedy or often longer-lived and part of climax forest. Certain southern pines, especially fire successional species, have a "grass stage," i.e.
, the stem of the young seedling elongates
little during the first several years and bears many long, curved
leaves, the plant then reminiscent of a dense clump
of grass
.
Nomenclature
used here, and to a very large degree
the taxonomy, follows Elbert L.Little Jr. (1971), former Chief Dendrologist, United
States Department of Agriculture, Forest Service. Much work is being done with problematic groups, particularly complexes in Pinus contorta, the pinyons, the bristlecone pines, and P . ponderosa and related taxa. Considerable chemotaxonomic and genetic data are available on the genus, but coverage is far from comprehensive. Therefore, the conservative approach used in this treatment emphasizes external morphology.
Pine (Pinus) has been adopted by Arkansas as the state tree. Southern pine (Pinus spp.) is the state tree of Alabama.[2]
