Description

Rumohra adiantiformis, the leather fern or leatherleaf fern, is a species of fern in the wood fern family Dryopteridaceae. It has a wide distribution, mainly in the tropical Southern Hemisphere. Other common names include leathery shieldfern, iron fern, 7-weeks-fern, and climbing shield fern. Growing to 90 cm (35 in) tall and broad, Rumohra adiantiformis is a bushy, tufted evergreen plant with glossy dark green fronds. These contain round sori (reproductive clusters) on the underside of the pinnae (leaflets) unlike many other ferns which have separate specialized reproductive fronds. Many of the sori have protective peltate indusia (films), and prominent scales on the stipes of the fronds. Rumohra adiantiformis is native to South America, the Caribbean, southern Africa, the Western Indian Ocean islands, Papua New Guinea, and Australasia. Countries it is native to include such diverse places as Brazil and Colombia, the Galápagos Islands, the Greater Antilles in the Caribbean, Zimbabwe and South Africa Australia, and New Zealand. An example of plant associations of Rumohra adiantiformis is found in the podocarp/broadleaf forests of Westland, New Zealand, with flora associates including Ascarina lucida, Pseudowintera colorata, Pseudopanax colensoi, Cyathea smithii and Blechnum discolor.
