The Restionaceae, also called restiads and restios, are a family of perennial, evergreen rush-like flowering plants native to the Southern Hemisphere and from 10 cm to 3 m in height. Based on evidence from fossil pollens, the Restionaceae likely originated some 60 million years ago during the Cretaceous period, when the southern continents were still part of Gondwana. The family consists of tufted or rhizomatous, herbaceous plants, superficially rush-like in overall appearance. They belong to a group of monocotyledons that includes several superficially similar families, such as the sedges, rushes and true grasses. They have green, photosynthetic stems and leaves that have been reduced to sheaths. Their flowers are extremely small and in spikelets, which in turn make up the inflorescences.
