A family of five genera worldwide ( Preussing et al. 2010; Rabeau et al. 2017), including three in Africa: Riccardia Gray , Aneura Dumort. and Afroriccardia Reeb & Gradst. The principal characteristics of Aneuraceae are: 1) thallus pinnate or unbranched; 2) midrib usually indistinct; 3) gametoecia at thallus margins or on short lateral branches; 4) sporophyte in a fleshy calyptra; and 5) elaters attached to the tips of the valves.
