Dennstaedtia davallioides

Rhizome long-creeping, much-branched, 3–5 mm diam., covered with short, cinnamon-brown hairs. Fronds distant, erect but drooping near tips, soft, 60–150 cm long. Stipe long, stiff, smooth and shiny, red-brown (sometimes dark), deeply but narrowly grooved; a few hairs near base. Lamina 3–4-pinnate, broad, somewhat triangular, mid- to dark green, delicate; hairs mostly along veins, short and colourless. Rachises mostly red-brown, shiny, narrowly grooved between prominent ridges; smaller rachises paler, with hairs on both surfaces (more numerous in grooves). Pinnae opposite to subopposite with lower primary pinna-pairs distant; pinnules markedly asymmetrical, decurrent (forming green wing along rachis), deeply and obliquely lobed; narrow lobules (or teeth) each having single vein. Sori as described above; cup-shaped indusial structure obvious when sorus mature.
