scales covering the entire structure except for the basal attachment point. Surface of mature gynoecia covered with numerous laterally fused hexagonal shields, 6–7 surrounding a micropylar tube, interseminal scales slender, long stalked, widened at the apical end, alternating with elongate oval ovaries with long micropylar tubes. Corona absent. Bracts not preserved.
