| 説明 | Native warm-season perennial slender, tufted C4 grass; stems are erect or ascending with a knee-joint near their base and to 70 cm tall. Flowerheads are a primary axis of racemes 10-30 cm long; branches are short, erect, often well-separated and pressed against the main stem; each branch ends in a small bristle. Spikelets are 2-flowered, 1.8–2.2 mm long and do not have a distinct constriction near their base; fertile lemma is weakly ribbed. Flowers from spring to early winter. Generally on low fertility soils in scrub, woodlands and forests. Most common in the north; mostly restricted to the Plains and western margins of the Slopes south of Dubbo. Native biodiversity. Abundance decline with increased fertility, probably due to greater competition from responsive species. An understorey species which is erect to semi-erect if ungrazed, but tends to grow horizontally with increasing grazing pressure. Of intermediate grazing value; it has moderate palatability and is not very productive. It goes to seed quite quickly, especially on poorer soils. Plants growing on better soils are more palatable and leafier. Increase under light grazing, but declines under heavy grazing; it is more important to provide regular rests as grazing pressure increases. |
