Mangart's flats, below ez jezik pass, 2.055 m, East Julian Alps, Posoje, Slovenia EC.Comment: Senecio abrotanifolius is an East Alpine - Illyric botanic element. In the West Alps and other European mountains one would search for it in vain. Apart of the East Alps it is limited to northwestern part of the Dinaric Mountains including Mt. Uka in Istria and Velebit Mountains at its most south occurrences. It is one of the flowering plants, which is not a common plant but sometimes appears massively and colors whole mountain slopes. Its large, deep orange-yellow heads reach up to 4 cm in diameter and deep green, shiny leaves are deeply divided. Hundreds of flower heads in large golden patches among white limestone scree and rocks and saturated green mountain grasses form truly marvelous vistas. Mt. Mangart's flats are especially rich in this sense. Genus Senecio is very large. Worldwide there are about 1.500 species known. Among 20 species of the genus, which grow in Slovenia, eight of them climb up into sub- and alpine elevations. All bloom in some shade of yellow. But Senecio abrotanifolius can be easily recognized by its two to three times deeply divided leaves with the terminal segments, which are only about one to two mm broad. In addition, large, deeply orange-yellow flowers heads are characteristic.Ref.:(1) A.
