Description
Genus Larix
Trees
deciduous; crown sparse, open. Bark
silver-gray to gray-brown on young trees, becoming reddish brown to brown, smooth
initially, scaly
to thickened and furrowed
with age. Branches whorled
; short (spur) shoots
prominent
on twigs
2 years or more old, each bearing leaves (needles
), and often pollen cone, or seed cone; lateral
long shoots (sylleptic branches) sometimes produced
by current-year growth increments
; leaf scars
many. Buds rounded
. Leaves in tufts of 10--60 on short (spur) shoots or borne singly on 1st-year long shoots, deciduous, ± flattened, with abaxial
keel, sessile, base
decurrent, sheath
absent, apex pointed
or rounded; resin canals 2. Pollen cones solitary, ovoid-cylindric, yellowish. Seed cones maturing in 1 season
, persisting several years, erect
, globose
to ovoid
, usually terminal
on short shoots and thus appearing stalked, sometimes sessile on 1-year-old long shoots; scales
persistent
, circular to oblong-obovate, thin, lacking apophysis and umbo; bracts included
or exserted. Seeds winged
; cotyledons 4--6. x
=12.
Species 10: boreal and cold north temperate
areas, North America, Eurasia
.
Species of Larix are present in most boreal regions; they often form only a minor component
of the vegetation. Some are important for their hard, heavy, and decay-resistant wood
. Only a few have received any horticultural attention; some cultivars exist for the most commonly cultivated Old World larches, L. decidua Miller and L. kaempferi (Lambert) Carrière, but almost none for the North American species.[1]
Habitat
Ecology: Woodlands and mixed forest at 2,300-3,500 m along various river systems .[2]
