Description: Rhizome long-creeping, slender, covered with brown or reddish, simple or sometimes glandular hairs.
Fronds erect, narrow- to broad-triangular, 2-pinnate or more compound, usually covered with short bristly or gland-tipped hairs.
Sori ± circular, marginal and terminal on a vein to submarginal and not quite terminal on a vein; indusium if present false, a reflexed or partially reflexed flap of the lamina at least partly covering marginal sori, or sometimes sori further from the margin and unprotected.
Distribution and occurrence: World: 40–45 species, chiefly tropical & southern temperate regions. Australia: 8 species, Qld, N.S.W., Vic., Tas.
Hypolepis distans has been transferred to the genus Hiya as Hiya distans and this transfer is accepted by Field (2020) but has not yet made its way into APC, and PlantNet is, for the moment, APC compliant.
