Tetraria is a genus of flowering plants in the sedge family, Cyperaceae, native to Tanzania, South Africa, Borneo, Australia and New Zealand. [3]
The type species is Tetraria compar (L.) P.Beauv. [4]
Recent molecular work has shown that Tetraria is polyphyletic and in need of revision. [5] [6]
Tetraria are perennial herbs, with generally few nodes. [7] The leaves are conspicuously sheathed with flat or incurved blades. [7] The inflorescence is usually a narrow panicle, with the flowers being bisexual, the lower flowers being male, and there are generally three stamens and three stigmas. [7] The fruit (a nutlet) is generally trigonous and often retains its style as a beak or crown. [7]

The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus Carex with over 2,000 species.
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, Australia and Southeast Asia. Others are found in scattered locations worldwide, from Europe to Asia, North Africa 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.
