Wall Rue, Asplenium ruta-muraria
Aspleniaceae or Spleenwort Family
A small, rock-loving fern with evergreen leaves that somewhat resemble parsley. Tiny, chestnut brown, oblong spore cases (sori) lie along the veins on the undersides of some leaves (the fertile leaves).
A somewhat rare native fern that likes limestone rocks in shady woods.
Rare in Wildwood, but known from several populations.
Most people would not recognize this as a fern, and as it has no flowers, they might not notice it at all. However, it is easily recognized if you look for rock-dwelling parsley-like plants.
