- Comments
- This subspecies is restricted to calcareous 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 of our latitudes. It has been lumped with A. trichomanes ssp. trichomanes in previous Virginia studies, and herbarium specimens, especially from limestone or dolostone outcrops, merit re-evaluation.
- Habitat
- Recent work by Jordan Metzgar at VPI has verified the presence of this subspecies in seven western Virginia counties, on both carbonate rocks of the Ridge and Valley and calcareous metamorphic rocks of the Blue Ridge. Similar habitats are common in western Virginia, and this fern is potentially much more widespread.
