Flora of Virginia Name/Status
Not in Flora of Virginia.
Carl Taylor (US) has studied this population of unusual wood ferns, which closely resemble Dryopteris clintoniana (D.C. Eat.) Howell and may represent a clone of considerably antiquity. He has determined that the plants are allotriploid, sterile hybrids of Dryopteris cristata and D. goldiana that produce irregular, abortive spores. Dryopteris clintoniana is a fertile allohexaploid which originated from the same progenitors, thus accounting for the morphological similarities. Both putative parents are present at the site, which is one of the largest and most diverse montane seepage wetlands in the state.
Forested seepage swamp with calcareous soils and groundwater; known from a single site on the northern Blue Ridge in Fauquier County.
