Macarthuriaceae is a family of plants in the orderCaryophyllales and consists of a single genus,Macarthuria.
Macarthuriaceae are rigid or wiry, rush-like herbs or subshrubs with green stems and reduced leaves.[2][5] The small flowers have five perianth members, sometimes also five "petals", and eight stamens fused at the base.[5]
In 2009,Macarthuria was placed withLimeum in theLimeaceae, based on its morphology, but at that time no molecular material ofMacarthuria had been examined.[6] Prior to this,Endress andBittrich had placed it in the familyMolluginaceae.[7] However, in 2011, molecular evidence was published, showing thatMacarthuria is sister to all coreCaryophyllales.[8][9] Thus,Macarthuria needed to be placed in a family of its own, Macarthuriaceae.[2][1]
