Status: | Native |
Description: |
Rhizome creeping, 2-8 mm in diameter; rhizome scales brown, awl-shaped. Fronds closely spaced, herbaceous, glabrous, erect or arching. Stipe up to 25 cm long, thin, wiry, dark brown to black, shining, glabrous. Lamina 2-3 pinnate, pinnate near the apex, triangular to ovate-deltate in outline, 20 × 18 cm. Rhachis and stalks black, shiny, glabrous. Pinnules persistent, 1-2.7 × 0.5-2 cm, wedge-shaped with straight sides, entire to deeply incised on the outer margin into narrow lobes. Lobes with outer margin minutely toothed, veins ending in the marginal serrations. Sori 2-5 beneath pinnule lobes on the undersurface of deflexed, membranous, oblong or slightly curved pale brown, glabrous indusial flaps. |
Notes: | Can be distinguished from other species (A. poiretii) by having persistent pinnules, oblong or lunulate sori and veins of the pinnules that end in the teeth of the serrations of the outer margins. |
Derivation of specific name: | capillus-veneris: hair of venus |
Habitat: | Terrestrial or lithophytic, on moist cliff faces, on boulders and along streams or moist ditches, in low-altitude woodland or medium-altitude riverine forest, exposed or shaded. Very occasional epiphytic on trees in spray of waterfalls. |
Altitude range: (metres) | Up to 1700 m |
Worldwide distribution: | Widespread in Africa, with the exception of West Africa. Throughout tropical, sub-tropical and warmer-temperate regions in the rest of the world. |
