Angiopteris
Quick Summary
Angiopteris is a genus of tree ferns belonging to the family Marattiaceae, which is considered one of the most primitive extant families of ferns. These ferns are characterized by stout, erect stems and can have very large leaves, with Angiopteris evecta reaching lengths of 7–9 meters. The distinguishing feature of the Angiopteris genus is its separate sporangia, which are the structures that produce spores. These sporangia are closely arranged in two rows, forming linear sori surrounded by scales. The Marattiaceae family is found in tropical and subtropical regions worldwide.123
