| 説明 | Native warm-season perennialslender hairless C4 grass; tufted or with short stolons; stems are flattened near their base, erect and to 50 cm tall. Flowerheads are digitate, with 3-8 branches, each 7-20 long and widely spreading at maturity. Spikelets are pressed against the stem, pointed and narrowed at the apex, laterally flattened, keeled and 2-flowered; lower fertile lemma is 2-3 mm long and awned; upper lemma is deeply 2-lobed, with an awn arising between the lobes. Flowers from late spring to autumn. Most commonly found on alluvial soils subject to periodic flooding (e.g. road drains, edge of wetlands); rarely abundant and more common in the north of the state. Native biodiversity. Good coloniser of bare ground. After warm-season rain it grows very quickly and provides moderately palatable feed; however, it has low productivity and runs to seed very quickly. Tolerant of grazing and tends to become more abundant under heavy grazing, but rests at flowering aid its persistence. |
