Description: |
Plants 5-30 cm high, branched in the upper half and each branch again branching 2 or 3 times, deltoid to ovate-lanceolate in outline, branchlets and leaves curling inwards when dry. Stems erect, tufted or closely spaced, 1 to 3 from a stout, shortly creeping rhizome. Leaves green on upper surface, pale creamy green through beige to almost silvery grey on lower surface, dimorphic, closely overlapping. Upper leaves up to 1.6 × 0.7 mm, ovate to oblong-lanceolate in outline, apex rounded, margin toothed, hyaline. 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. |
