    • n asplenium A genus of ferns characterized by linear or oblong sori lying on the veins (which are free in most species) and obliquely to the costa, the involucre being conformable to the sorus and opening toward the costa when single. It is the largest genus of the order (Filices) excepting Polypodium, and its species are found in all parts of the world, wherever ferns grow. It includes very varied forms. Many of the species are evergreen, and some are cultivated for their beauty. Among the more common species, generally known as spleenwort, are the lady-fern (A Filix-fæmina), black maidenhair (A. Trichomanes), distributed around the globe, wall-rue (A., Ruta-muraria), and ebony spleenwort (A. ebeneum).
