| 説明 | Introduced, warm-season, annual or short-lived perennial, erect, woody legume 60-150 cm tall. Leaves have 3 leaflets, each nearly stalkless, linear to lanceolate, hairless above, sparsely hairy below and 3-4 cm long. Flowerheads are long racemes with about 40 pea-like flowers. Petals are yellow with brown veins. Fruit are 20-35 mm long, cylindrical pods that hang downwards on the stem. Flowering is from summer to autumn. A native of tropical Africa, it is mostly found in disturbed places (e.g. roadsides, wasteland, ploughed land), but also in open grassland, woodland, wet sclerophyll forest and rainforest margins. Is not toxic to stock and has been utilized as a pasture species overseas, though palatability is low. Other Crotalaria species have been suspected of being toxic. Regarded as a weed, but has potential as a green manure crop on low fertility soils where the growing season is long. |
