| 説明 | Native, yearlong-green, perennial, scrambling-climbinglegume, with stolons. Leaves have 3 leaflets, each 3-10 cm long, sparsely hairy and ovate. The central leaflet has a longer stalk than the lateral leaflets. Flowerheads are racemes of 2-12 yellow to greenish-yellow, 12-25 mm long, pea-like flowers in the leaf axils. Pods are drooping, cylindrical, hairy and 4-8 cm long. Flowering is over most of the year. Found north from the Macleay Valley in damp-wet areas where the annual rainfall exceeds 1200 mm. Tolerant of acidity, waterlogging, short-term flooding and shade, but not drought or frost. Native biodiversity. Not commonly sown as no commercial seed, even though it is one of the best legumes for wet conditions and a useful pioneer species. Easily established, very palatable, non-bloating and relatively high yielding (especially compared to other legumes in moderate to dense shade). It is preferentially grazed and can only withstand short periods of heavy grazing (appropriate rest periods are essential). Stands will persist for 3 or more years and production is maximised if soil phosphorus is maintained at moderate (or better) levels and lenient grazing is used. Remove stock when there is still plenty of vine and some leaf to maximise persistence and production. The more leaf left on the plant, the faster the regrowth. |
