| 説明 | Introduced, semi-erect, cool-season, annual, herbaceous legume to 60 cm tall. Leaves trifoliate, leaflets 30-50 mm long, covered in white hairs; the stalks of each leaflet are of similar length. Flowerheads are 4 to 8 cm long cylindrical spikes, with many flowers. Calyx dries to stiff, hard bristles when the plant dies off. Corolla is pink to purple and not persistent. Pods are small and held inside the calyx at maturity. Flowering is in spring and early summer. Widely naturalised, generally where moisture accumulates such as roadsides and creek lines; also in moister areas of natural pastures, shrublands and woodlands. It is not regarded as either a weed or a desirable pasture component. Only of minor forage value as it does not produce a significant amount of leaf. Not particularly palatable as it has hairy stems, leaves and flowers; flowers also become quite bristly when they mature. |
