Summary
[edit]DescriptionCyperus brevifolius flowerhead2.jpg |
English: Introduced warm-season perennial slender grass-like sedge, mostly 5-20 cm tall and with long rhizomes. Leaves are bright green, shiny, hairless and grasslike. Flowerheads are green, oval and 3-7 mm across; with numerous (up to 100), densely-packed spikelets. Flowering is from spring to early autumn. A native of tropical regions, it is a weed of lawns, pastures and disturbed areas. An indicator of wet, poorly drained situations. Produces little bulk and of little importance for grazing animals. Can become abundant in wet years, but becomes less common in dry years. Generally control is not required. If invasive, it can be controlled by improving drainage and sowing pasture species that are tolerant of waterlogging. |
