Adiantum hispidulum, commonly known as Rough Maidenhair Fern or five-fingered jack, is a small fern in the family Pteridaceae of widespread distribution. It is found in Africa, Australia, Polynesia, Malesia, New Zealand and other Pacific Islands.[2] Its fronds rise in clumps from rhizomes among rocks or in the soil in sheltered areas.

Adiantum hispidulum was first described by Swedish botanist Olof Swartz in 1802.[3]
Its species name is derived from the Latin hispis “hair” and means “minutely hairy”.[4] Five Fingered Jack is an alternate vernacular name.[5]
Adiantum hispidulum grows in tufts or clumps among rocks or from the ground, its fronds arising from the short dark clumped rhizomes. The dark stipe measures up to 45 cm (18 in) in length. The fronds are divided into long and short narrow triangular or elliptic pinnae, each of which is divided again into smaller roughly rectangular, diamond-, or fan-shaped pinnules. Each pinnule may have 1 to 20 sori along its margins underneath. Young growth may have a pinkish tinge before it matures into the dark green foliage.[2][6]
Adiantum hispidulum is grown as an ornamental plant that adapts readily to cultivation, although may be slow growing. It is more tolerant of sun and drying out than other fern species.[4]
