There genus names are Larix and Abies . Both Larix and Abies belong to the family Pinaceae.
Larches differ from most other conifers because they are deciduous.
They lose their needle-like leaves in the fall and new leaves appear in the spring. There are three basic Larch types that live in North America. Larches not only differ from other conifers by being deciduous but their needles are arranged differently. On older twigs they arise from woody pegs that resemble barrels in dense clusters of twenty-forty. The American Larch has a straight slender trunk with light horizontal branches.
