Rhizome short, covered with dark brown, shiny scales with long, fine tips. Fronds clustered, weak and trailing, 10–50 cm long; tip often without pinnae, sometimes taking root and producing plantlets (these usually preceded by a group of small dark scales). Stipe short, slender, green to light brown, flattened above with slight groove, with a tuft of scales at base, but none further up. Lamina once pinnate, linear to narrowly oblong, tapering towards tip, pale green, membranous; rachis slender, green, grooved with narrrow green wings, extending into long, bare tip. Pinnae shortly stalked, relatively distant, 6–20 pairs, usually fan-shaped, sometimes 3-lobed, larger towards base, 2–15 mm long; outer margin toothed; veins forking repeatedly, radiating. Sori linear-oblong, oblique to midvein, not reaching margin, occasionally confluent; indusium oblong, thin, with irregular margin, opening towards centre of pinna.
