Restionaceae
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.[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.The vast majority of species, though, are to be found in the Cape Floristic Region and particularly plentiful on hard sandstone formations.Also, many smaller species offer a great variety of decorative features and deserve horticultural attention.The Cronquist system of 1981 also recognized this family and placed it in the order Restionales, in the subclass Commelinidae in class Liliopsida in division Magnoliophyta.
