Pollen cones ellipsoid, ca. 15mm, yellow. Seed cones maturing in 2 years, variably serotinous, mostly whorled, downcurved, asymmetric, ovoid before opening, broadly ovoid when open, (4–)6–10cm, gray- to pale red-brown, nearly sessile or on stalks to 1cm; apophyses thickened, diamond-shaped, strongly keeled, elongate, mammillate at cone base abaxially; umbo central, a stout, curved, sharp claw. Seeds deltoid-obovoid, oblique; body ca. 6mm, deep purple-brown to black; wing 10–20(–30)mm. 2n =24.
