Genera:Pinus (pine), Picea (spruce), Abies (fir)
Family Name:Pinaceae – pine family
General Description:Pines, spruces and firs are members of the Pinaceae family and share basic morphological and reproductive characteristics. Pines, spruces and firs are needle-bearing, pyramidal trees (at least when young) with branches growing in a whorled pattern. They are monoecious, cone-bearing plants. To the casual observer they look very much the same and are frequently lumped together and called a “pine” or often “a Christmas tree”. Since the most important features of a plant family are the reproductive structures, this Plant Profile will focus on the male, female and seed bearing structures of Pinaceae.
