Scots Pine, Pinus sylvestris L.
DISTINGUISHING CHARACTERISTICS: Leaves in bundles of 2, slender, 1 to 4 inches long, usually twisted and often marked with fine white lines (seen with magnifying glass). Cones 1 to 2 inches long, falling intact (i.e., basal scales not missing); end of scales raised and pyramidal (less commonly flattened), with or without tiny prickles. Bark scaly and light orange on larger branches and upper trunk, divided into large gray plates covered with orange scales on lower trunk.
SIMILAR TREES: Mugo pine is shrubby; other common two-needle pines have longer leaves. Mature Scots pines can be easily distinguished from other species y the orange bark of their upper trunk and limbs.
