Needles 2-5 per bundle, triangular in cross section, 3.5-7 cm × 1-1.5 mm, vascular bundle 1, resin canals 2, marginal, sometimes also 1 median, base with sheath shed. Seed cones usually solitary, pedunculate (peduncle 0.7-2 cm), reddish brown at maturity, cylindric-oblong or cylindric-ovoid, 3-9(-17) × 1.5-7 cm, slightly resinous. Seed scales cuneate-obovate, 2.5-3.5 × 1.5-2.3 cm; apophyses rhombic, apex thin, straight or slightly incurved. Seeds ellipsoid or obovoid, 0.8-1.2 cm, together with wing subequal to seed scales.
