Cyperus zollingeri, commonly known as roadside flatsedge,[1] is a sedge of the family Cyperaceae that is native to tropical areas of Australia,[2] Africa and Asia.

[3] The annual herb or grass-like sedge typically grows to a height of 0.1 to 0.4 metres (0.33 to 1.31 ft) and has a tufted habit.

In 1854 the botanist Ernst Gottlieb von Steudel classified it by the current name in the work Synopsis Plantarum Glumacearum.
