Plant ± erect with main stem 10–40 cm tall, glabrous, much branched in the upper part; rhizophores filiform, present only at the base, yellowish, ± 2 cm long. Stolons often numerous, originating at base of stem, often well developed and 15–20 cm long, bearing small leaves. Branches pinnate or bipinnate, narrowly lanceolate to ovate-elliptic in outline. Leaves glossy, strongly dimorphic save at base of main stem, with midvein almost reaching apex and margin hyaline, spaced in lower parts but imbricate in upper parts; lateral leaves 4–6 × 2–2.8 mm, with 2 false nerves one on each side of midrib, minutely toothed, unequilateral, the acroscopic half lanceolate, rounded at base, acute at apex, the basiscopic half oblong often rounded at base, obtuse at apex; median leaves obovate-elliptic in outline, 2–2.5 × 1 mm, rounded at the base, minutely toothed, apex ending abruptly in a long very narrow bristle-like point; axillary leaves ovate-lanceolate in outline, ± 3 × 1.5 mm, wedge-shaped at base, apex pointed, minutely toothed, with 2 false nerves as in lateral leaves. Strobili solitary at apices of ultimate branchlets, 6–8 × 1–3 mm. Sporophylls uniform, broadly triangular, convex, ± 1.5 mm long, 0.7–0.8 mm wide, narrowly acute at apex, with hyaline ciliate margins; spores of two kinds. |
