Description

Tree to 30(-40) m tall, with slender trunk to 0.6(-1) m in diameter. Bark very gray, cracking into flakes and then plates with age. Branchlets thinly short hairy at first, scarcely to strongly grooved. Buds 2-4(-4.5) mm long, heavily white-resinous. Needles arranged to the sides and above the twigs, directed exclusively upward on high branches, (1-)1.5-2.5(-5) cm long, shiny bright green above, the tips shallowly notched or rounded on lower branches to pointed on those bearing seed cones. Individual needles flattened to plump in cross section and with a resin canal on either side just inside the lower epidermis or deep within the leaf, without stomates above or with a few short lines of stomates near the tip and with four to seven lines in each dull light green stomatal band beneath. Pollen cones about 15 mm long, red. Seed cones elongate egg-shaped, 5-8(-10) cm long, 2-4 cm across, deep purple when young, maturing light reddish brown. Bracts only about a third as long as the seed scales and hidden by them. Persistent cone axis narrowly conical. Seed body 5-6 mm long, the wing up to twice as long. Cotyledons four or five.

Northern and central Eurasia from northeastern European Russia and the southern Ural Mountains across Siberia (hence the species name) north of the Chinese and Mongolian border region to the Uda and Amur Rivers and central Heilongjiang province (China), with an outlier in the Tian Shan (Kyrgyzstan).
