—larcher, adj./lahrch/, n.1. any coniferous tree of the genus Larix, yielding a tough durable wood.2. the wood of such a tree.[1540-50; earlier larche < MHG L laric- (s. of larix) larch]
* * *Any of about 10–12 species of coniferous trees that make up the genus Larix of the pine family, native to cool temperate and sub-Arctic regions of the Northern Hemisphere.Though the larch has the pyramid shape typical of conifers, it sheds its short, light-green, needlelike leaves in autumn. The most widespread North American larch, the tamarack, or eastern larch (L. laricina), matures in 100–200 years, may grow 40–100 ft (12–30 m) tall, and has gray to reddish-brown bark. Coarse-grained, strong, hard, and heavy, larch wood is useful in ship construction and for telephone poles, mine timbers, and railroad ties.
* * *▪ treeany of about 10 to 12 species of coniferous trees constituting the genus Larix of the family Pinaceae, native to cool temperate and sub-Arctic parts of the Northern Hemisphere. One species, Larix griffithii, is found only in the Himalayas. A larch has the pyramidal growth habit typical of conifers; but the leaves are shed in autumn, like deciduous trees. The short, needlelike leaves are arranged spirally on new growth and in whorls at the tips of short spurs on older twigs. There are 10 to 30 soft, light-green needles on each spur. The related golden larch has cones that disintegrate at maturity; those of Larix species often remain on the trees several years, then fall intact.The most widely distributed North American larch is tamarack, hackmatack, or eastern larch (L. laricina). The bracts on its small cones are hidden by the scales. Eastern larch trees mature in 100 to 200 years. This species may grow 12 to 20 metres (about 40 to 65 feet) tall and have gray to reddish-brown bark. A taller species, the western larch (L. occidentalis) of the Pacific Northwest, has bracts that protrude beyond the cone scales.The European larch (L. decidua), native to mountainous areas of northern and central Europe and Siberia, usually is 24 to 42 metres (about 80 to 140 feet) tall. It has reddish-gray bark and produces a clear oleoresin known as Venetian turpentine.Several species of Larix are grown as ornamentals, especially the Japanese larch (L. leptolepis) and L. decidua ‘Pendula,' a cultivar of the European larch. Larch wood is coarse-grained, strong, hard, and heavy; it is used in ship construction and for telephone poles, mine timbers, and railroad ties.
