sensitive fern family
Species in the family Onocleaceae are terrestrial ferns that have running, horizontal stems (rhizomes) underground. There are two genera in New England, each with a single species. The sterile leaves are deciduous and are produced early in the season; fertile leaves are produced later, are dark-colored and last through the winter. The sori are hidden beneath hardened, inrolled leaf edges. Species in the Onocleaceae were formerly considered to belong to the Polypodiaceae.
