DistributionThroughout the Coastal Plain, the southeastern 60% of the Piedmont, and the southernmost Mountains. Scattered in the northwestern Piedmont, but seemingly absent in most of the Mountains.

This is a Southeastern species, ranging from NS, ME, and MO, south to the Gulf Coast from FL to TX.
AbundanceCommon and widespread in the Coastal Plain and the southeastern half of the Piedmont; rare to uncommon in the northwestern Piedmont. Infrequent in the southern border counties in the Mountains, but nearly absent elsewhere in the province. Populations usually are composed of large patches of plants.
HabitatThis is one of the most common wetland ferns in the state, growing in acidic soils of pocosins, bogs (in the Mountains), streamhead ecotones, swamps, blackwater bottomlands, wet pools, and many types of alluvial forests. It will tolerate some mowing and will persist in lawns where formerly there were streamheads.
PhenologyFruits from June to September.
IdentificationThis is a familiar wetland species of acidic soils, generally where shaded. It has separate fertile and sterile fronds, quite different from each other. On the sterile frond, the stipe is rather greenish in color and about 10-12 inches long, with the leathery blade about the same length, and about 5-6 inches wide, generally ovate in shape. There are 7-10 pairs of pinnae, distinctly alternate, not dissected or lobed into pinnules, each with straight edges and about 2-3 inches long with a pointed tip. The blade of Sensitive Fern (Onoclea sensibilis) is somewhat similar but has opposite pinnae and each pinna has shallow lobes. The fertile frond is about as tall as the sterile one, with a long stipe as well. However, the handful of pairs of pinnae are very narrow but still 2-3 inches long, mostly ascending, and are green in color for several months but turn brown in the fall season, often remaining into the winter.
Taxonomic CommentsThe species was long named as Woodwardia areolata. Note that the other former Woodwardia in the eastern US -- W. virginica -- is now in a separate genus -- Anchistea.
