cones maturing in 2 years, shedding seeds and falling soon thereafter, pendent, symmetric, lance-cylindric before opening, broadly lance-cylindric when open, 15–25cm, creamy brown to light yellow-brown, stalks to 6cm;

apophyses somewhat thickened, strongly cross-keeled, tip reflexed;

umbo terminal, low.

cones maturing in 2 years or variably serotinous, variably persistent, spreading to reflexed, often curved, nearly symmetric or variably asymmetric, lanceoloid to ovoid before opening, broadly ovoid to nearly globose when open, 2–6cm, tan to pale red-brown, lustrous, nearly sessile or on stalks to 1cm;

apophyses nearly rhombic, variously elongate, cross-keeled, often mammillate toward outer cone base and on inside above middle;
