Marattiales

Class Marattiopsida is a group of ferns containing a single order, Marattiales, and family, Marattiaceae. Class Marattiopsida diverged from other ferns very early in their evolutionary history and are quite different from many plants familiar to people in temperate zones. Many of them have massive, fleshy rootstocks and the largest known fronds of any fern. In this group, such fronds are found in the genus Angiopteris, native to Australasia, Madagascar and Oceania. These fronds may be up to 7.5 meters (25 feet) long. In Jamaica the species Angiopteris evecta is widely naturalized and is registered as an invasive species. The plant was cultivated in the Castleton Gardens in 1860 and was able to distribute itself from there. This article explains how to read a taxobox. ... Angiopteris evecta. ...

This plant order also contains the King Fern, Marattia salicina, known in Maori as Para. Sometimes called the Potatoe Fern, this is a large Australasian fern with an edible fleshy rhizome that is used as a food source by some indigenous peoples.
