Leontodon autumnalis L.[1]

Scorzoneroides autumnalis, commonly called autumn hawkbit,[2] is a perennial plant species, widespread in its native range in Eurasia (from Europe east to western Siberia),[3] and introduced in North America.[4]

The plant is sometimes called fall dandelion, because it is very similar to the common dandelion (one of the main differences being a branched stem with several capitula[5]), but "yellow fields", covered by this plant appear much later than dandelions, towards the autumn in the Eastern Europe. In the Latin synonym of the plant name, Leontodon autumnalis,[6]"leontodon" means "lion's tooth", the same as "dandelion".


Description[edit]

Scorzoneroides autumnalis is a perennial herb growing to 35 cm high usually with branched stems and several flower-heads each about 30 mm across. The florets are all ligulate and bright yellow. The leaves are all basal and linear-oblong.[6]

Reproduction[edit]

Flowers in June to October producing achenes.[6]

Habitat[edit]

Frequent in damp grassland[6] and meadows.[7]

Ecology[edit]

The fly Tephritis leontodontis is known to attack the capitula of this plant.[8]

Distribution[edit]

Abundant in Ireland and Great Britain.[7]
