Psaronius is an extinct genus of marattialean tree fern that grew up to about 10 m tall during the Carboniferous to Permian periods, known mainly from petrified stems and root mantles. It is not a plant you can grow, so care fields are not applicable.
Psaronius is an extinct genus marattialean tree fern which grew to 10m in height, and is associated with leaves of the organ genus Pecopteris and other extinct tree ferns. Originally, Psaronius was a name for the petrified stems, but today the genus is used for the entire tree fern. Psaronius tree fern fossils are found from the Carboniferous through the Permian.
