Original diagnosis/description
Plant with smooth stems and strobili terminating in clusters of ovoid sporangia, their bases tapering into short, straight stalks. Distal sporangia more widely separated. Sporangia spit longitudinally into two equal valves that lack thickened margins. Strobilar axis and stalks with central, longitudinally orientated ?vascular strands. Strobilar axis 2-3mm wide with central strand c.0.4 mm in diameter. Sporangial maximum diameter 2.5–3.5 mm (x = 2.8 mm, n = 30), approximate height 4–7.5 mm (x = 5.6 mm, n = 26). Stalk width 0.6–2.0 mm, central trace 0.2 mm wide, length approximately 1–2 mm.
