Leaves green on upper surface, pale creamy green through beige to almost silvery grey on lower surface, dimorphic, closely overlapping.

Lateral leaves 1.8-2 × 1.0-1.2 mm, asymmetrically broadly ovate in outline, apex pointed, base adnate to the stem, margin lacerate-serrate and hyaline. Strobili 5-11 mm long, at tips of ultimate branches, male below, female above. Sporophylls uniform, ovate, pointed, margin toothed, smaller and more contracted than the sterile leaves.
