Trichomanes intricatum
Closeup of T. intricatum
Trichomanes intricatum is known as the weft fern.[1] 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.[2]
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. [3]
In 2011, Atsushi Ebihara and Alan S. Weakley transferred Trichomanes intricatum to Crepidomanes intricatum based on the chloroplast molecular sequence data.[4]
