Supaia
Extinct genus of fern-like plant
Supaia is an extinct genus of fern-like plants, possibly seed ferns.[2] Species belonging to the genus lived during the Permian[3] in North America,[3] east Asia,[4] and Madagascar.[5] The leaves were adapted to minimize water loss, and the genus is thought to have grown as small trees (up to 4 meters (13 ft) in height) in a mudflat environment subject to frequent drought.[6]
