| 説明 | Native, warm-season, perennial, Loosely tufted, erect grass; to 60 cm tall and with a densely hairy swollen base. Leaves are flat, 3-6 mm wide and often sprinkled with hairs with warty bases. Flowerheads vary from digitate to a primary axis of racemes. Branches are 4-10 in number, rigid, and widely spreading at maturity; they mostly lack spikelets near their base and lower branches are whorled. Spikelets are paired, 3.75-5 mm long, 2-flowered and hairy. Flowers from late spring to autumn. Usually found in woodlands on better soils and often in areas prone to periodic flooding (e.g. next to waterways and roadsides). Also occurs on sandy and duplex soils, but is uncommon on heavy clays. It has low frost tolerance, but high drought tolerance. Native biodiversity. When abundant it is considered to be useful for stock as it grows rapidly after summer rains, is palatable and has high feed value prior to flowering, but productivity is low to moderate. Strategic spelling from grazing improves production and persistence. |
