Original diagnosis/description

Branches bearing scale-like leaves in opposite decussate pairs. Branchlets sub-opposite to alternate, irregular. Leaves generally of two forms: facial and lateral. Facial leaves of branchlets ovate-obovate, apex acute to subacute, with median ridge in places; those of branches oblong, with acute-obtuse apex. Lateral leaves of branches and branchlets rhomboidal to falcate, apices acute. Microsporangiate cone solitary, terminal on branchlets; each microsporophyll probably bearing 2–5 pollen sacs at its base. Seed cone globose to oblong, probably borne terminally on branchlets, perhaps bearing 4–5 pairs of bract/scale complexes; complexes rhomboidal with distinct subapical umbo. Number of ovules per complex probably one (not clearly discernible).
