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): the family now includes the former families Anarthriaceae, Centrolepidaceae and Lyginiaceae, and as such includes 51 genera with 572 known species. Based on evidence from fossil pollens, the Restionaceae likely originated more than 65 million years ago during the Late Cretaceous period, when the southern continents were still part of Gondwana.
Ehrharta is a genus of plants in the grass family.
Deschampsia is a genus of plants in the grass family, commonly known as hair grass or tussock grass. The genus is widespread across many countries.
Danthonia is a genus of Eurasian, North African, and American plants in the grass family. Members of this genus are sometimes referred to as oatgrass, but that common name is not restricted to this genus. Other common names include heathgrass and wallaby grass. Australian species have since been reclassified into the genus Rytidosperma.
Helictotrichon, or alpine oatgrass, is a genus of perennial flowering plants in the grass family. The genus name comes from the Greek heliktos meaning twisted, and trichos meaning hair, referring to the shape of the awn.
Setaria is a widespread genus of plants in the grass family. The name is derived from the Latin word seta, meaning "bristle" or "hair", which refers to the bristly spikelets.
Arthraxon, commonly known as carpetgrass, is a genus of Asian, African and Australian plants in the grass family, Poaceae, containing the following species:
Orthoclada is a genus of African and Neotropical plants in the grass family.
Urochloa is a genus of plants in the grass family, native to Eurasia, Africa, Australia, Mexico, and the Pacific Islands. Common names include signalgrass.
Danthonioideae is a mainly southern hemisphere subfamily of grasses, containing the single tribe Danthonieae and one unplaced genus, with altogether roughly 300 species. It includes herbaceous to partially woody perennial or annual (less common) grasses that grow in open grasslands, shrublands, and woodlands. It belongs to the PACMAD clade of grasses, but unlike some other lineages in that clade, grasses in the Danthonioideae exclusively use the C3 photosynthetic pathway. Its sister group is the subfamily Chloridoideae.
Cannomois is a group of plants in the Restionaceae described as a genus in 1828. The entire genus is endemic to Cape Province in South Africa.
Merxmuellera is a genus of African grasses named for Hermann Merxmueller, a 20th century German botanist and taxonomist who was an expert on African flora.
Tenaxia is a genus of Asian and African plants in the grass family.
Pentameris pictigluma is a species of flowering plant in the family Poaceae, native to Cameroon in West Africa, Ethiopia to Tanzania in East Africa, and Yemen. It was first described by Ernst Gottlieb von Steudel in 1854 as Aira pictigluma.
