| 説明 | Introduced warm-season perennial tufted bluish-green C4 grass; stems are erect and to 150 cm tall. Flowerheads are spatheate panicles 15-40 cm long, with many paired racemes (branches). Racemes are 1.5-5 cm long and have 5-7 awns. Spikelet are white-haired and paired (1 stalked and awnless, the other unstalked and awned). Flowers from spring to autumn. A native of Africa, it is most common on lighter soils in disturbed low-fertility areas such as roadsides, wasteland and native pastures; it can also invade undisturbed areas. Tolerant of a wide range of soil types and is very drought tolerant. A serious weed of poorer soils, it often forms monocultures, excluding most other species. A very vigorous grass that makes strong warm-season growth. Young new growth is palatable, but it quickly becomes coarse and unpalatable at flowering. Needs to be kept short to prevent seeding and maintain feed quality, but will seed in as little as 2-3 weeks after grazing or slashing. Tolerant of burning, heavy grazing and regular slashing. |
