Seed cones solitary or paired toward branchlets tips, sessile or rarely shortly pedunculate, dark brown, ovoid-cylindric when open, 15-25 cm, maturing in 2 years, then quickly shedding seeds and falling. Apophyses dull, nearly rhombic, slightly thickened and raised, strongly cross keeled; umbo broadly triangular, with a short, stiff, reflexed prickle.
