The rough maidenhair fern, whose botanical name is adiantum hispidulum, is a small fern in the pteridaceae family.
This fern, also known as the five-fingered jack, is found in Africa, Australia, Polynesia, Malesia, New Zealand, and other Pacific islands.
These ferns grow in clusters or clumps among rocks or from the ground, and their midribs emerge from rhizomes in short dark clumps.
The leaves are divided into elongated triangular or oval pinnae, each further subdivided into smaller nearly oblong, diamond-shaped, or fan-shaped pinnae.
