Seed cones 1-3 together, terminal, globose, ovoid, or cylindric-ovoid; bracts and cone scales spirally arranged, sessile, connate proximally; bracts persistent, broadly ovate or triangular-ovate, flat, large, leathery, base cordate, margin irregularly and finely serrulate, apex long acuminate, hard; ovules 3 per bract axil, sessile; cone scales of mature cones sessile on and fused to proximal middle part of abaxial side of bract, minute, distal part free, 3-lobed, lobes irregularly serrulate at apex.

The minute cone scales of Cunninghamia have often been overlooked, and in much of the literature what is termed the cone scale is in fact the bract.
