Branchlets pendulous; long shoots puberulent, yellow-brown, graying with age; short shoots 3-4 mm diameter, brownish yellow, densely pubescent. Leaves linear, 12-35 × 1 mm, keeled on both sides. Seed cones brownish purple, maturing brown, cylindric-ellipsoid, 2.5-4 × 1.5-2 cm. Seed scales obovate-reniform, 8-11 × 10-13 mm, lower surface densely pubescent, apex emarginate. Bracts exserted, dark brown-purple, broadly lanceolate, reflexed, 11-15 mm long. Seeds light gray, obliquely obovoid, 7-9 mm long including wing.

Timber is used for construction, railroad ties, and furniture, and the bark yields tannins. The species is also used for afforestation (Wu and Raven 1999).
