Black spleenwort, scientifically known as Asplenium adiantum-nigrum, is a species of fern found in many parts of the world. It gets its name from the black central stem, or rachis, that supports the compound leaves. This perennial plant typically grows on walls, rocks, and in woods, preferring damp and shaded areas. It is characterized by its pinnate leaves and small, round sori (clusters of spore-producing structures) on the underside of the leaves.
