(true pines; family Pinaceae)
A genus of resinous, evergreen conifers in which the leaves (needles) are borne in groups of twos, threes, or fives on short shoots borne along the twigs. There are separate male and female cones, the latter with woody scales; the seeds are winged. Many pines are important for timber, also yielding resin and turpentine. There are 93 species, all in the northern hemisphere, occurring mainly in northern temperate regions, extending in America and eastern Asia to the seasonal tropics. The common name ‘pine’ is sometimes used to describe other pine-like trees of different genera (e.g. Araucaria araucana. Chile pine or monkey-puzzle tree), or, loosely, to include all conifers.
