Description |
Plants bluish-green from a robust, wide-creeping rhizome; erect stems 20–50 cm, branched and sparsely hairy beneath in the upper 1/2. Outline of branch-system broadly ovate to lanceolate, acute or rarely flagelliform at the apex; secondary branches broadly lanceolate to linear-lanceolate in outline dichotomising 2–6 times; ultimate branchlets 0.6–1.5 cm long; the lowermost basiscopic tertiary branch conspicuously larger than the acroscopic one. Leaves heteromorphic; stem-leaves ovate-lanceolate in outline, apex gradually tapering to a sharp point, margins finely serrate, becoming ciliate at the cordate clasping base, 2–3 mm long; median leaves similar, 3 mm long, apex abruptly tapered into whitish seta 1/4 as long as leaf; lateral leaves (of secondary branches) linear with an acute apex or linear-lanceolate, adnate at the base, margin sinuous, sparsely toothed becoming ciliate towards the base, 4 x 1 mm. Strobili 1.0–1.5 cm, at tips of ultimate branches, maturing ± simultaneously, bearing sporangia at the base and towards the top; sporophylls of 1 kind, broadly ovate tapering to a setose apex, margins dentate becoming ciliate at the base. Megaspores of 2 sizes. |
