Nat. Ord. (Natural Order) Coniferï¿½. Lin. Syst. (Linnean System) Monï¿½cia, Monadelphia. The Larch is a resinous, cone-bearing tree, belonging to the Pine family, but differing from that genus in the annual shedding of its leaves like other deciduous trees. In Europe it is a native of the coldest parts of the Alps and Appenines; and in America, is indigenous to the most northern parts of the Union, and the Canadas. The leaves are collected in little bunches, and the branches shoot out from the main stem in a horizontal, or, more generally, in a declining position.
