Cibotium (from Greek κιβώτιον, kibṓtion, "little chest" or "box"), also known as manfern,[1] is a genus of 11 species of tropical tree ferns.

The natural habitat of Cibotium is among the dripping trees and stream gullies of the rainforests on Hawaiʻi's windward volcanic slopes.

The fossil record indicates that the genus was once a part of the boreotropical flora found in Europe, eastern North America, and western Asia.

In traditional Chinese medicine, it is used as an anti-inflammatory and an anodyne; its rhizome hairs are used in Malaysia and China as a styptic for wounds.

[10] Hair-covered pieces of the rhizome, with bud stalks imitating legs, were used to lend credence to the medieval legend of the Vegetable Lamb of Tartary, a half-sheep, half-plant hybrid.
