Kyllinga nemoralis (white kyllinga).

Abstract

Kyllingia nemoralis is a perennial sedge native to the tropical Old World that has been introduced elsewhere in Oceania, the Indian Ocean and the Americas. Several species of Cyperaceae are listed as highly invasive worldwide. Sedges of the genus Kyllinga are recognized for their invasive tendencies in tropical climates. K. nemoralis exhibits characteristics common to the success of an invasive species, such as asexual spreading, positive reaction to human-caused disturbance, early and consistent reproduction and small seeds. In the tropics, it can be competitive with grass species and is sometimes aggressive in lawns, turf and pasture. A related species K. polyphylla, is a major weed of improved pastures, but can be suppressed by competition from vigorous, well managed grasses. K. nemoralis is listed as invasive in a number of islands in the Pacific and Indian Oceans.
