Plant bright apple green, erect or suberect with branched main stem or prostrate with ascending branches, 3–40 cm long or tall, sometimes in dense stands; rhizophores 2–3 cm long born only at base of stem; stolons pale yellow, forming a right-angle with the stem, developing small bulbils at the tips, with very small leaves. Leaves dimorphic; lateral leaves well spaced on principal stems, closer on branches, ovate-oblong, ovate-lanceolate to lanceolate, 1.75–3 mm long, 0.5–1.8 mm wide, acute at the apex, amplexicaul at base (in primary leaves), acroscopic half leaf semi-ovate, rounded at the base, serrulate, basiscopic half leaf semi-oblong subtruncate at base, subentire; median leaves broadly lanceolate or ovate, 2–3 mm long, ± 1 mm wide, produced at apex into a fine serrated tip, 1/3–1/2 length of leaf, margins of thick-walled hyaline cells, ciliate-denticulate; axillary leaves broadly lanceolate, ± 2.2 mm long, 1.2 mm wide, acute, serrulate. Strobili 4–5(–12) mm long, ± 2 mm wide. Sporophylls dimorphic; dorsal oblong, 1.8 mm long, 0.5 mm wide, acute at apex, ciliolate-denticulate towards apex, with pale keel; ventral hyaline, ovate-triangular, 1.7–1.8 mm long, 0.8 mm wide, aristate, serrulate. Megaspores pale yellow, 250–300 µm in diameter, granulate; microspores red, 25–40 µm in diameter, covered with broad flat verrucae.
