Angiopteris

Angiopteris is a genus of huge evergreen ferns from the family Marattiaceae, found throughout the paleotropics from Madagascar to the South Pacific islands.

They feature a large, erect, woody rhizome with a wide base supported by thick roots. The fronds are deltoid, pinnate, long, with spreading leaflets. At the base of the fronds is a pair of thick, leathery stipules — in the case of A. canaliculata, measuring up to long and wide. Species of smaller stature with elongate synangia and creeping rhizomes are sometimes segregated into the genus Archangiopteris, and a once-pinnate monotypic segregate genus has been called Macroglossum, but molecular data supports inclusion of these taxa within a broad concept of Angiopteris.
