Rumohra adiantiformis is a fern species from the family Dryopteridaceae. It is native to a diverse range of countries in the Caribbean, South America, southern Africa, Australasia, Papua New Guinea, and islands in the West Indian Ocean.
Rumohra adiantiformis is an evergreen herbaceous fern species growing up to 2’-4’ feet depending on the growing conditions. The dark green-colored, lacy-looking, finely-cut, glossy, and triangular-shaped fronds give the plant a tropical appearance. A feature of leather leaf distinguishing it from most other fern species is it does not have separate reproductive fronds. Instead, the reproductive clusters, called sori, are located on the underside of the leaflets. Since the fern species spreads slowly, it is suitable for growing in small spaces, pots, and hanging baskets as well. Common names include Leather Fern, Leather-leaf Fern, Leathery Shield Fern, Iron Fern and 7-weeks Fern.
