Female cones cylindrical, isolated, erect, terminal in position on ultimate branches, with spirally disposed bracts and in each of their axils one fan-like ovaliferous scale, which is most frequently deeply fivelobated in the upper expanded half, contracted to a sort of petiole in the lower one and bear 2-3 ovate seeds on the lower part of the expanded portion. Whether the scales are simple or not cannot be accurately determined. Seeds with a narrow membranous margin.

Shoots bearing spirally arranged bifacial leaves. Observed width of axes
up to 5 mm; axes together with leaves up to 30 mm. Leaves slightly overlapping,
straight. Different shapes and dimensions of leaves indicating heterophylly:
(1) Shape narrow-subtriangular with acute apex; observed dimensions up to 35 mm
long, 6 mm wide; leaf base rhomboid, slightly decurrent; this type of leaves
possibly originating from main axes; (2) Shape ovate, apex obtuse, observed

Conifer. Shoots bearing spirally arranged bifacial leaves. Heterophylly
may occur. Shape of bracts rhomboid with acute apex. Ovuliferous dwarf-shoots

planes of symmetry, provided with a single or several sterile scales forming median
