Asplenium adiantumnigrum
Definition
A fern species in the genus Asplenium, popularly known as black spleenwort; it grows on siliceous rocks, old stone walls, and acidic soils in temperate regions. It is characterized by ovate-lanceolate, bi- or tri-pinnately divided fronds of a glossy dark green, supported by rigid stipes that are brownish-black at the base, a structural chromatic trait from which the specific epithet 'adiantum-nigrum' originates.
