Trichomanes intricatum
Closeup of T. intricatum
Trichomanes intricatum is known as the weft fern. This is an unusual filmy fern that grows in rock shelters and crevices in the eastern United States, being known only from its gametophyte generation. It is a rare plant that is protected in several states.[1]
Recent study has found a relationship between this species and an Asian filmy-fern species, Crepidomanes schmidtianum. Both share the same chloroplast genome. The relationship is uncertain. [2]
In 2011, Atsushi Ebihara and Alan S. Weakley transferred Trichomanes intricatum to Crepidomanes intricatum based on the chloroplast molecular sequence data.[3]
