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]
