Description

Macarthuriaceae are rigid or wiry, rush-like herbs or subshrubs with green stems and reduced leaves.[3][5] The small flowers have five perianth members, sometimes also five "petals", and eight stamens fused at the base.[5]

Taxonomy

In 2009, Macarthuria was placed with Limeum in the Limeaceae, based on its morphology, but at that time no molecular material of Macarthuria had been examined.[6] Prior to this, Endress and Bittrich had placed it in the family Molluginaceae.[7] However, in 2011, molecular evidence was published, showing that Macarthuria is sister to all core Caryophyllales.[8][9] Thus, Macarthuria needed to be placed in a family of its own, Macarthuriaceae.[3][2]

gollark: Yep!
gollark: Hmm, 6 million actually.
