The common name dandelion (/ ˈ d æ n d ə l aɪ. ən / DAN-də-ly-ən; from French dent-de-lion 'lion's tooth', referring to the jagged leaves) is also given to specific members of the genus. [8] Like other members of the family Asteraceae, they have very small flowers collected together into a composite flower head.
Taraxacum officinale, the dandelion or common dandelion, [6] is a herbaceous perennial flowering plant in the daisy family, Asteraceae. The common dandelion is well known for its yellow flower heads that turn into round balls of many silver-tufted fruits that disperse in the wind. These balls are called "clocks" in both British and American ...
Taraxacum ceratophorum, also known as the horned dandelion, is a species of flowering plant within the genus Taraxacum and family Asteraceae. [1] This alpine species has a preference for mountainous habitat, where it can be found growing at elevations up to 3000 meters above sea level. [ 2 ]
Taraxacum arcticum is a moderately long-lived perennial with a whitish taproot and a rosette of five to eight green leaves, sometimes growing solitarily and sometimes somewhat matted. The leaves are 5 to 10 cm (2 to 4 in) long and 1 to 1.5 cm (0.4 to 0.6 in) wide, and have several deep lobes and a long triangular final lobe.
Taraxacum kok-saghyz, often abbreviated as TKS and commonly referred to as the Kazakh dandelion, rubber root, or Russian dandelion, [1] [2] is a species of dandelion native to Kazakhstan, Kyrgyzstan and Uzbekistan, notable for its production of high-quality rubber. [3]
The red-seeded dandelion can also be identified by its leaves, which have consistently triangular lobes throughout, whereas T. officinale tends to have erratic lobing with minimal or no triangular form. The leaves of T. erythrospermum thus bear a closer resemblance to the basal leaves of sow thistles (Sonchus oleraceus). [citation needed]
Crepis tectorum is identified by its long, erect stem and yellow, dandelion-like flowers. [4] The leaves are pointed and lobed with a length of 10–15 centimetres (3.9–5.9 in) and width up to 4 cm (1.6 in). [4] The flower heads look like they contain single flowers, but in fact they contain many ray florets. [4]
The lower leaves are 10 to 30 cm long, lanceolate, keeled lengthwise, grey-green, pointed, hairless, with a white midrib. The upper leaves are shorter and more erect. It is the only United Kingdom dandelion-type flower with grasslike leaves. [3]
