larch (redirected from European larches)

larch, any tree of the genus Larix, conifers of the family Pinaceae (pine family), which are unusual in that they are not evergreen. The various species are widely distributed in the Northern Hemisphere. Needles of the larches are mostly borne in characteristic radiating clusters. A western American larch (L. occidentalis) achieves a great height, and its lumber is used for interior construction, ties, posts, and cabinetmaking. The American, or black, larch (L. laricina), commonly called also tamarack and hackmatack, ranges from the Arctic Circle to cold swamps in more temperate regions of the NE United States and is cultivated elsewhere for its beauty. The wood of this species has been used in shipbuilding and for posts, ties, and poles. The European larch (L. decidua) has long been valued for its durable wood and as a source of Venice turpentine. This tree, the Japanese larch (L. leptolepis), and the Siberian larch (L. sibirica) are also cultivated for ornament. The related golden larch is Pseudolarix amabilis. Larch is classified in the division Pinophyta, class Pinopsida, order Coniferales, family Pinaceae.

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.

Larch - The Larch Project develops aids for formal specifications. Each Larch specification has two components: an interface containing predicates written in the LIL (Larch Interface Language) designed for the target language and a 'trait' containing assertions about the predicates written in LSL, the Larch Shared Language common to all. ["The Larch Family of Specification Languages", J. Guttag et al, IEEE Trans Soft Eng 2(5):24-365 (Sep 1985)].
