| Description: |
Plants in colonies or large isolated clumps. Rhizome erect to procumbent, massive, c. 6 mm in diameter; rhizome scales hard, up to 20 mm long, dark brown, linear-lanceolate in outline, margins irregular to lacerate. Fronds erect to arching, tufted, coriaceous, up to 2.5 m long. Stipe brown, up to 0.8 m long (up to 1/3 of total frond length). Lamina pinnate with a free conform terminal pinna, roughly lanceolate in outline. Sterile pinnae petiolate, glabrous, linear to oblong-lanceolate in outline, margin entire to wavy, apex rounded to bluntly pointed, base unequally wedge-shaped, usually directed forward at about 45° from the rhachis and facing upwards; midrib prominent on lower surface; venation visible on upper surface with areoles. Fertile pinnae similar in size and shape to sterile pinnae, or sometimes slightly smaller, undersurface entirely covered with sori. |

| Derivation of specific name: | aureum: golden, possibly referring to the golden-brown colour of the ripening sporangia in our specimens. |
| Habitat: | Mostly in coastal mudflats, mangrove forest and reedbeds, in or near estuaries, at inland springs, exposed or lightly shaded.
In south-eastern Zimbabwe it was recorded next to some hot springs, in peatlike soil with salt efflorescences. |
