Ammannia mauritiana is a synonym of Ammannia capitellata, the plant known as Nesaea triflora.36 It received this name, now regarded as illegitimate, temporarily in 2013, when all Nesaea species were moved to Ammannia and A. triflora was already taken.34 It occurs on Madagascar, Réunion, Mauritius and the Comoros; Kenya, Tanzania, India and Sri Lanka are also listed.46
The aquarium plant goes back to an import made in 2000 from the Ambodimanga in eastern Madagascar, where the species grows in the floodplain, among others alongside Myriophyllum mezianum.36 The submersed leaves are yellowish to light green with reddish marbling; in weak light they stay small, while in strong light the shoots turn reddish and grow sturdily.56 The clone is considered adaptable and also grows in moderately hard water without CO₂; other sources recommend CO₂ under medium to strong light.56
