Species in the genus Marattia of plants

Fern - Conservation plans have been proposed for Ptisana purpurascens, an endemic of the distant Ascension Island in the South Atlantic, where a single population remains on Green Mountain. This population is now believed to be more stable than previously feared, but long-term threats to its survival do exist, in the form of competition with alien invasive species like introduced plants such as Lantana camara and grazing by sheep.
