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