Roots proliferous. Base fronds rounded to reniform, 5–45 cm diam.; upper part spreading and nest-like, bluntly and deeply lobed, to 3 times forked, remaining green for a long time. Foliage fronds ascending to pendulous, 22–105 cm long; base narrowly cuneate, 0–5 times forked; ultimate divisions strap-shaped, 0.5–3.2 cm wide; first fork usually at or below middle of frond, 1 division often remaining undivided following forking of the frond, the latter thus appearing to divide in threes; upper surface green, ± sparsely stellately hairy; lower surface greyish green, ±densely covered with stellate hairs. Sporangia covering most of the undersurface of ultimate segments of foliage fronds, sometimes reaching around sinus of first fork, sometimes not reaching apex. Spores 50–67.5 µm long, 25–35 µm wide.
