The Family Pinaceae (Lindley, 1836), or the Pine family, is in the Order Pinales and includes most of the well-known conifers of commercial importance such as cedars, firs, hemlocks, larches, pines and spruces, in 11 genera and between 220-250 species (depending on taxonomic opinion). These trees and shrubs are mostly found in the North Temperate zone, grow from 2 to 100 m tall, are mostly evergreen (except Larix and Pseudolarix, deciduous), resinous, monoecious, with subopposite or whorled branches, and spirally arranged, linear (needle-like) leaves. Male cones are small and herbaceous; female cones are large and usually woody. Seeds occur two to a scale and are usually winged. Embryos are multi-cotyledonous.
