Marsh Fern


Thelypteris palustris
Thelypteridaceae

This is a very common fern in wet, sunny areas. It can be found inhabiting the moist edges of wetland areas. Fertile fronds, 18-24 inches in height, have leaf edges that are slightly rolled over the spore-bearing sori. These rolled edges distinguish the Marsh Fern from its relative Massachusetts Fern.
