Coronidium rupicola, commonly known as the yellow button,Шаблон:R is a flowering plant in the family Asteraceae. It is a small, upright, perennial shrub with yellow flowers borne on a single stem and is endemic to Queensland, Australia.

Description

Coronidium rupicola is a small, shrubby, erect perennial with a single stem and terminal yellow button flower-heads about Шаблон:Cvt in diameter. Unlike other species of Coronidium it doesn't have conspicuous, large bracts, instead a ring of smaller, narrow light-coloured bracts. The florets are thickly crowded with a greenish centre. The flowers in bud are thickly covered with long, whitish hairs, new growth stems silvery and woolly. The leaves are narrow, lanceolate, Шаблон:Cvt long, pale green, densely woolly underneath, upper surface smooth, margins rolled under and wavy. Flowering occurs throughout the year and the fruit is a cypsela.[1]

Taxonomy

This species was first described in 1838 by Augustin Pyramus de Candolle as Helichrysum rupicola.[2] In 2008 Paul Graham Wilson published a paper titled "Coronidium, a new Australian genus in the Gnaphalieae (Asteraceae)", in which he erected the new genus Coronidium and transferred this species to it. It was published in the journal Nuytsia.[3][4]

Etymology

Wilson coined the genus name Coronidium from the Greek words korone (crown) and the diminutive -idion, a reference to a feature seen on the fruit after bristles have broken away from it.Шаблон:RШаблон:Rp The specific epithet rupicola is derived from the Latin words rūpēs meaning "cliff", and -cola meaning "to inhabit", and is a reference to the habitat where this species is found.[5]

Distribution and habitat

Yellow button is endemic to Queensland and grows on rocky coastlines, road verges, woodland and exposed ridges.[1][3]Шаблон:Rp
