| 説明 | Introduced, cool-season, annual, ascending to erect, slender herb, 15-50 cm tall. Leaves are very finely divided into linear or threadlike segments that are less than 1 mm wide. Flowerheads are umbels in the leaf axils; they have small flowers with very small (about 0.3 mm long) white petals. Fruit are small and strongly ribbed; these are longer lasting and more likely to be noticed than the flowers. Flowering is from late winter to early summer. A native of America, it occurs in disturbed pastures, gardens and waste places. It is more abundant in moist areas, but is also found in drier areas during wet years. An indicator of disturbance and bare ground. It is a minor component of many pastures and regarded as an insignificant weed. It is relatively unpalatable to stock and only grazed when there is little else on offer. It may taint milk when present in sufficient quantities. Control can be achieved by maintaining strong dense pastures. |
