Plants terrestrial, evergreen or seasonally green, shortly creeping, fertile erect stem 2-5 cm, with creeping or prostrate stems. Rhizophores restricted to lower part of erect fertile branches or to middle of main stem, borne on ventral side in axils of branches. Main stems branched throughout, stramineous, 0.3-0.4 mm in diam. in lower part, terete, not sulcate or sulcate; primary leafy branches 3 or 4 pairs, simple or forked or once pinnately branched, branchlets sparse, adjacent primary branches on main stem ca. 1 cm apart; leafy portion of main stem including leaves 3-4 mm wide at middle. Axillary leaves on branches symmetrical or slightly asymmetrical, ovate, 1.2-2 × 0.6-1 mm, base exauriculate, margin ciliolate in basal half, upward denticulate. Dorsal leaves ± symmetrical, those on main stems not obviously larger than those on branches; dorsal leaves on branches contiguous, ovate, 1.2-1.6 × 0.6-1 mm, slightly carinate, base subcordate or obtuse, margin minutely denticulate, apex acuminate or aristate. Ventral leaves asymmetrical; ventral leaves on branches spreading, ovate or ovate-lanceolate, 1.6-2 × 1.6-2 mm, apex acute; basiscopic margin subentire or minutely denticulate to apex; acroscopic base enlarged, broader, overlapping stem and branches, margin ciliolate. Strobili solitary, terminal, compact, dorsiventrally complanate, 4.5-13 × 2-4.5 mm; sporophylls strongly dimorphic, resupinate, white-margined; dorsal sporophylls minutely denticulate, with sporophyll-pteryx incomplete (ending midway to apex) and ciliolate; ventral sporophylls ovate-triangular, margin ciliolate, all known sporophylls megasporophylls; megaspores greenish-yellowish orange.

Main stem shortly creeping, 2–10 cm long, rooting throughout its length; branches erect or ascending, 3–5 cm long. Median leaves ovate to narrowly ovate, c. 0.75–1.5 mm long; base slightly asymmetrical; margins denticulate; apex long, acute, usually recurved. Lateral leaves oblong-ovate to ovate, c. 1.5–2 mm long, asymmetrical; margins ciliate on the acroscopic rounded base, denticulate above; apex broadly acute or obtuse. Strobili c. 5–20 mm long; sporophylls in a median position bearing megasporangia, ±symmetrical, keeled, ovate, acuminate with long-ciliate margins; sporophylls in a lateral position bearing microsporangia, spreading, asymmetrical, oblong-ovate, acuminate; margins denticulate, ciliate at base. Megaspores 216–264 µm diam., finely reticulate, verrucose. Microspores 19–38 µm diam., finely granulose to tuberculose.
