Common name
Description	Rhizome shortly creeping, short, up to 10 mm in diameter; rhizome scales chestnut to rust-coloured, 5-7 mm long, narrowly lanceolate in outline, margin entire. Fronds closely spaced, tufted, few, spreading or erect, up to 90 cm long, slightly dimorphic with fertile fronds slightly longer than sterile fronds. Stipe 2-22 cm long, sparsely to densely set with mixture of hairs and scales, becoming glabrous at maturity. Lamina coriaceous, 5.3-63.5 cm long, narrowly elliptic in outline, pinnate to 2-pinnatifid, with 7-34 pairs of pinnae. Pinnae ovate to narrowly ovate in outline, hairless or nearly so on upper surface, undersurface with hairs and scales along the rhachis and veins; pinnule margins shallowly crenulate to obtusely toothed. Rachis densely set with hairs and scales. Sori marginal at lobe apices, exindusiate.
Notes	Difficult to distinguish from M. vestita. M. nudiuscula has a thickly coriaceous and often a less dissected lamina with hairless or nearly hairless upper surface; the margins are notched with shallowly rounded teeth.
Derivation	nudiuscula: somewhat bare or naked, the upper surface of the lamina is almost hairless.
Habitat	Seasonally moist montane grassland and forest margin, rocky places by waterfalls, exposed or shaded.
Distribution worldwide	Africa, Madagascar.
Distribution in Africa	Dem. Republic of Congo , Lesotho , Malawi , Mozambique , South Africa , Tanzania , Zambia , Zimbabwe .
Growth form	Terrestrial.
