Comments
This species is restricted to carbonate rock outcrops at northern latitudes and is potentially more widespread in western Virginia. However, it is a far northern-ranging species and may be infrequent or rare at the lower elevations where carbonate rocks occur at our latitudes. It has been lumped with A. trichomanes ssp. trichomanes in previous Virginia studies, and herbarium specimens from limestone or dolostone outcrops merit re-evaluation.
Habitat
To date, this taxon is known in Virginia from a single collection: on limestone rocks along Sinking Creek, Giles County (M. Hicks 78705 at BOON). Similar habitats are common in the Virginia Ridge and Valley, and this fern is potentially much more widespread.
Native Status
Native
