"Ceterach officinarum", called "Asplenium ceterach" by many authors, is a fern species commonly known as Rustyback. It is characterised by an short rhizome which gives rise to several green fronds that have a pinnated lamina with trichomes on the abaxial surface, but not the adaxial one. The petiole is shorter than the corpus of the leaf.

This species is found in Western and Central Europe, including the Mediterranean region. It is associated with fissures in carbonate rocks.

This fern species has been used medicinally as a diuretic.
