It belongs to the Aspleniaceae family. It grows in Europe, while in Central Europe it is a protected plant. In Greece, we find it with the common names skorpidi, asplinio, skorpidochorto, skorpidatsi, skopirotiri, chrysochorto, or agriosparti. Rustyback is fairly widespread in the crevices of rocks and in crevices of old walls, preferring the walls facing north. The ancient Greeks used it for their diuretic and expectorant properties.
