Carlina corymbosa
''Carlina corymbosa'', common name Clustered Carline Thistle, is a herbaceous perennial plant in the genus ''Carlina'', belonging to the family Asteraceae.
==Description==
''Carlina corymbosa'' reaches on average in height. This plant has rhizomatous roots, overwintering buds situated just below the soil surface (hemicryptophyte)〔(''Herbario Virtual'' )〕 and an almost leafless stalk growing directly from the ground (scapose). The stem is green to whitish, thick and erect. The leaves are alternate, sessile or amplexicaul and lobed with spines on the margins.〔Pignatti S. - Flora d'Italia – Edagricole – 1982, Vol. III, pag. 214〕
The yellow flowers are terminal, in diameter and surrounded by thorny bracts. The outer bracts are similar to leaves, while the inner bracts surrounding the disk florets are membranous and stiff, with a golden color. The flowering period extends from June through August. The flowers are hermaphrodite and are pollinated by insects (usually bees, wasps and butterflies) (entomogamy). The fruits are achenes long, each with a feathery yellow pappus. Seed dispersal is by wind (anemochory).〔 Julve, Ph., 1998 ff. - The French Flora Database (Baseflor ) 〕
