Genus Onoclea is a group of fern species that are commonly referred to as the "Sensitive Ferns". The genus name is derived from the Greek words "onos" meaning donkey and "kleio" meaning to close, as the leaves of the plant are said to resemble the ears of a donkey and tend to wilt at the first sign of drought or frost.
Other synonyms for the Genus Onoclea include the "Beaded Fern", "Chain Fern", "Interrupted Fern", and the "Woolly-Leafed Fern". Each of these names is derived from a particular distinguishing characteristic of the fern species, such as the small bead-like structures found on the fronds of the Beaded Fern, or the characteristic gaps found in the frond of the Interrupted Fern.
