Pinaceae (/pɪˈneɪ.siː/), also known as the pine family, is a family of coniferous trees and shrubs, including many of the well-known conifers of commercial importance such as cedars, firs, hemlocks, larches, pines and spruces.
Etymology
The name Pinaceae is derived from the genus Pinus, which is the Latin name for the pine tree.
Description
Members of the Pinaceae family are trees or shrubs, mostly evergreen, with resinous wood. The leaves are simple, spirally arranged, needle-like or scale-like, and often sheathed at the base in early leaf development. The plants are mostly monoecious with both male and female cones on the same plant.
