Oleandra distenta Kunze

distenta: extended, stretched out; possibly referring to the widely spaced fronds on the widely creeping rhizome.

Rhizome long creeping, up to 4 mm in diameter, scandent, branched; rhizome scales appressed, shiny, lanceolate, up to 7 mm long, with a dark brown central stripe and paler ciliate margins. Roots thin, wiry, singly below each old frond. Fronds widely spaced on rhizome or on short side branches, erect to arching, deciduous, simple. Stipe articulated near the base, up to 6 cm long, covered with scattered scales similar to, but smaller than those on the rhizome. Lamina 14-33 × 1.5-6.5 cm, glabrous on both surfaces, thinly membranous (dry) to thinly coriaceous, linear lanceolate in outline, base wedge-shaped, apex abruptly ending in a tip, margin subentire, wavy; midrib prominent below; veins obvious, simple, sometimes forked near the costa, finely parallel. Sori circular, up to 2.5 mm in diameter, in a irregular line on either side of the midrib, situated within the inner half of the lamina; indusium round to kidney-shaped, small, hairless, dark brown, entire.

Widespread in tropical and southern Africa.
