Did you know?
This fern was last seen in New York on Iona Island in the Hudson River in 1954. There are other historical records from the 1800s from Highlands, NY and the northern tip of Manhattan. The genus name refers to the marginal sori (cheilos=marginal and anthos=flower) and the specific name refers to the woolly leaf stalks.

State Ranking Justification [-]
All of the historical locations were surveyed, yet no plants were found. There does seem to be potential habitat at a few of the historical locations and in adjacent areas. This provides hope that this plant is indeed persisting somewhere within the state. More survey work is needed to determine if this plant might be located somewhere within the state.
