Diagnosis

Bracts spatulate to lanceolate with rounded apexes arising perpendicularly in a loose spiral from the axis, curving toward the apex, and continuing almost parallel to the axis; bracts extending beyond the ovuliferous organs and several times as long as the vegetative leaves. Ovuliferous scales with an apical whorl of 9–13 elongated segments, apical part of the segments pointed, oriented parallel to the axis or directed outward (abaxially). Seed attachment areas on the adaxial side, in central position. Leaves of the ultimate shoots below the cones closely spaced, basally partially imbricated, much longer than wide, entire margin, and rounded apex.
