Cibotium (from Greek κιβώτιον, kibṓtion, "little chest" or "box"), also known as manfern,[1] is a genus of 11 species of tropical tree ferns. It is the only genus in family Cibotiaceae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I).[2] Alternatively, the family may be treated as the subfamily Cibotioideae of a very broadly defined family Cyatheaceae,[3] the family placement used for the genus in Plants of the World Online as of November 2019[update].[4]
