Angiopteris is a genus of huge evergreen ferns from the family Marattiaceae, found throughout the paleotropics from Madagascar to the South Pacific islands. Species of smaller stature with elongate synangia and creeping rhizomes are sometimes segregated into the genus , and a once-pinnate monotypic segregate genus has been called , but molecular data supports inclusion of these taxa within a broad concept of Angiopteris. Angiopteris is unique among ferns in having explosively dispersed spores, thought to be caused by the cavitation of an airspace between spore layers.
