The fronds of species within this genus 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 peltate indusia and have prominent scales on the stipes of the fronds. Species have a wide distribution; for example, Rumohra adiantiformis is found in the Old World as well as the New World, including such diverse places as the Galapagos Islands[3] and New Zealand.
