Didymochlaena is a genus of fern with only one species, Didymochlaena truncatula, also known under the synonym Didymochlaena sinuosa.[1] In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is the only genus in the family Didymochlaenaceae.[2] Alternatively, the family may be placed in a very broadly defined family Polypodiaceae sensu lato as the subfamily Didymochlaenoideae.[3] It is commonly grown as a house plant, and is sometimes known as the mahogany maidenhair.
