释义
dandelion
plant
weedy perennial herb of the genus Taraxacum of the family Asteraceae, native to Eurasia but widespread throughout much of temperate North America. The most familiar species is T. officinale.
It has a rosette of leaves at the base of the plant; a deep taproot; a smooth, hollow stem; leaves that may be nearly smooth-margined, toothed, or deeply cut; and a solitary yellow flower head composed only of ray flowers (no disk flowers). The fruit is a ball-shaped cluster of many small, tufted, one-seeded fruits. The bitter young leaves are used in salads, and the roots can be used to make a coffee-like beverage.
