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]
Description
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]
