  • Description

    Description - Evergreen trees with two kinds of leaves, the primary ones linear or scalelike, deciduous, the secondary ones forming the ordinary foliage, narrowly linear, arising from the axils of the former in fascicles of 2-5 (rarely solitary in some western species), subtended by the bud-scales, some of which are united to form a sheath. Staminate aments (flowers) borne at the bases of shoots of the season, the clusters of stamens spirally arranged, each in the axil of a minute scale; filaments very short; anthers 2-celled, the sacs longitudinally dehiscent. Ovule-bearing aments (flowers) solitary or clustered, borne on the twigs of the preceding season, composed of numerous imbricated minute bracts, each with an ovule-bearing scale in its. axil, ripening into a large cone, which matures the following autumn, its scales elongating and becoming woody. Seeds 2 on the base of each scale, winged above, the testa crustaceous. [Name Celtic] About 100 species, of the northern hemisphere. Type species: Pinus sylvestris L.
