Leontodon autumnalis L.[1]

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

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

Flowers in June to October producing achenes.[6]

Habitat

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

Ecology

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

Distribution

Abundant in Ireland and Great Britain.[7]
