Rhizome often climbing, grey-green, fleshy, 3–7 mm diam., scaly when young; scales brown, appressed, shiny, acuminate, deciduous. Fronds widely separated, erect or drooping, variable in size and shape, 5–50 cm long, firm in texture; stipe glabrous with scales clustered at swollen base. Lamina narrowing abruptly at base, shiny, light green with clear, thickened margins, simple and oblong to linear-lanceolate, or irregularly pinnately lobed with long terminal segment and 1–9 pairs of lateral lobes, each 5–15 cm long; scales scattered on undersurface of central vein, small, broad and inflated. Veins prominent, branching repeatedly to form network, main lateral veins dark, forming areoles enclosing free vein endings; enclosed veins usually bifurcate (often unbranched near margins of lamina), sometimes more than once bifurcate (particularly near midvein); submarginal vein continuous and wavy. Sori globose, 2–5 mm diam., slightly sunken (showing as raised circle on upper surface), in 2 rows, each about halfway between midvein and margin, without indusium.
