The Restionaceae are a group of rush-like plants found in southern parts of the world, particularly Africa, Australasia and southeast Asia. Leaves are commonly reduced to sheaths around the photosynthetic stems. Smaller species that retain distinct linear or setaceous leaves have historically been distinguished as a separate family Centrolepidaceae.
