Encyclopedia > Siberian Larch

The Siberian Larch, or Russian larch, (Larix sibirica) is a frost-hardy tree which occurs naturally in northeastern Russia and western Siberia. It has been raised in Canada and in the northern United States, but only in a limited way. At maturity, the tree may attain a height of 130 feet (40 m). Siberia Siberia (Russian: , common English transliterations: Sibir’, Sibir; from the Tatar for “sleeping land”) is a vast region of Russia and northern Kazakhstan constituting almost all of northern Asia. ...

Larix sibirica was first cultivated in 1806. The minimum seed-bearing age is 12 years. Flowering dates are April to May. Male and female flowers are borne separately on the same tree. The male flowers are solitary, yellow, globose-to-oblong bodies that bear wingless pollen. The female flowers are small cones that ripen the first year. A ripe cone is made up of brownish, woody scales, each of which bears two winged seeds. The length of a cone is 1 to 1½ inches (2.54 to 3.81 cm), but the length of a seed is much less. Properly stored seeds remain viable for 25 years or more. 1806 was a common year starting on Wednesday (see link for calendar). ...

Genus Larix

Genus Larix includes ten species. The larches are cone-bearing, deciduous trees widely distributed over the cooler regions of the Northern Hemisphere. They grow in almost any kind of soil, including clay and limestone, but they develop best when grown in the open on somewhat moist, but well-drained soils. Because of its rot resistance, larch wood is especially valuable for posts, poles, railroad ties sleepers, and mine props. Deciduous means temporary or tending to fall off (deriving from the Latin word decidere, to fall off). ... The Northern Hemisphere is the half of a planets surface (or celestial sphere) that is north of the equator (the word hemisphere literally means half ball). On Earth, the Northern Hemisphere contains most of the land and population. ... Sleepers has several meanings: for the 1996 film, see Sleepers (film) for railway sleepers, see railroad tie Sleepers is also a solo album by rapper Big Pooh from the group Little Brother. ...

The larches hybridize readily. L. leptolepis X sibirica, known as L. marschlinsii Coaz, was originated in 1901. 1901 was a common year starting on Tuesday (see link for calendar). ...

Larch - LoveToKnow 1911 (2310 words)
The larch abounds on the Alps of Switzerland, on which it flourishes at an elevation of 5000 ft., and also on those of Tirol and Savoy, on the Carpathians, and in most of the hill regions of central Europe; it is not wild on the Apennine Branchlet of Larch (Larix europaea).
The Siberian larch has smooth grey bark and smaller cones, approaching in shape somewhat to those of the American hackmatack; it seems even hardier than the Alpine tree, growing up to latitude 68°, but, as the inclement climate of the polar shores is neared, dwindling down to a dwarf and even trailing bush.
The thinnings of the larch woods in the Highlands are in demand for railway sleepers, scaffold poles, and mining timber, and are applied to a variety of agricultural purposes.
Larch - Wikipedia, the free encyclopedia (499 words)
Larches are conifers in the genus Larix, in the family Pinaceae.
Larches are among the dominant plants in the immense boreal forests of Russia and Canada.
Larch cones are erect, small, 1-9 cm long, green or purple, ripening brown 5-8 months after pollination; in about half the species the bract scales are long and visible, and in the others, short and hidden between the seed scales.
