Bogrushes

Schoenus is a predominately austral genus of sedges, commonly known as bogrushes, or veldrushes in South Africa. Species of this genus occur mainly in South Africa (some 44 species), Australia (some 70 species) and Southeast Asia. Others are found in scattered locations worldwide, from Europe (2 species) to Asia, North Africa (1 species) and the Americas. Three species occur in the peatlands of southern South America, including S. antarcticus which is found in Tierra del Fuego, where it forms a component of hyperhumid Magellanic moorland.

Taxonomic attention to the South African taxa, starting 2017, revealed a wealth of species. Twenty-four species were transferred from Tetraria and Epischoenus into Schoenus, and several new species were described. S. inconspicuus, discovered on the outskirts of Cape Town, consists of only a few specimens.
