Mature ♀ cones 1–6, 7–12 mm diam. before dehiscence, ± globose; peduncles stout. Scales 6, thick, broadly rhomboid, the outer ones c. 1/2 length of others and more tapering towards apex; boss in upper ⅓ of scale, short and broadly conic or rhomboid; apex mucronate. Central column short. Seeds many, dark brown. Cones persisting for several years after dehiscence and sometimes enlarging in that time.
