Pinus sylvestris, Linn. Scotch or Scots Pine. Tree, to 70, or occasionally 120 ft., with spreading, often somewhat pendulous branches, pyramidal when young, with broad and round-topped often picturesque head in old age: branchlets dull grayish yellow: winter-buds oblong ovate, brown, resinous: lvs. rigid, acute, twisted, bluish green, 1 1/2 - 3 in. long: cones short-stalked, conic-oblong, grayish or reddish brown, 1 1/2 -2 1/2 in. long; apophysis little thickened, slightly keeled, only those near the base elongated; umbo small, obtuse; seed dark gray, 1/6 in. long. Eu. to W. and N. Asia. —One of the most important timber trees of Eu. It is quite hardy, but has little to recommend it as an ornamental tree.

Varieties

  • Pinus sylvestris var. sylvestris. The bulk of the range, from Scotland and Spain to central Siberia.
  • Pinus sylvestris var. hamata Steven. The Balkans, northern Turkey and the Caucasus. Foliage more consistently glaucous all year, not becoming duller in winter; cones more frequently with a pyramidal apophysis.
  • Pinus sylvestris var. mongolica Litv. Mongolia and adjoining parts of southern Siberia and northwestern China. Foliage duller green, shoots grey-green; leaves occasionally up to 12 cm long.
  • Pinus sylvestris var. nevadensis D.H.Christ. The Sierra Nevada in southern Spain and possibly other Spanish populations. Cones often with thicker scales, but doubtfully distinguishable on morphology.
