Seed cone ovoid, ca. 35 mm long and ca. 30 mm wide. Bract-scale complexes swollen to form a mound around the apical third, supplied with a single vascular strand from cone axis, which firstly divides into abaxial and central adaxial bundles; central adaxial bundle bifurcating once horizontally; abaxial bundle dividing horizontally into 8–10 smaller bundles; 2 lateral adaxial bundles, each branched from abaxial bundle on a lateralmost side; resin canal placed both adaxial and abaxial to the vascular strands. Ovuliferous scale fused to bract except for each lateral margin; apical part trilobed.
