The Restionaceae, also called restiads and restios, are a family of flowering plants native to the Southern Hemisphere; they vary from a few centimeters to 3 meters in height. Following the APG IV (2016):[1] the family now includes the former families Anarthriaceae, Centrolepidaceae and Lyginiaceae, and as such includes 51 genera with 572 known species.[2] Based on evidence from fossil pollen, the Restionaceae likely originated more than 65 million years ago during the Late Cretaceous period, when the southern continents were still part of Gondwana.[3][4]

Distribution

A number of the largest African species have become popular as garden ornamentals in many parts of the world, some being useful as accent plants similar to small species of bamboo, but with pendant stems of greater delicacy. Also, many smaller species offer a great variety of decorative features and deserve horticultural attention.
