Coronidium rupicola, commonly known as the yellow button, [1] 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.
Coronidium rupicola is a small, shrubby, erect perennial with a single stem and terminal yellow button flower-heads about 2 cm (0.79 in) 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, 5 cm (2.0 in) 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. [4]
This species was first described in 1838 by Augustin Pyramus de Candolle as Helichrysum rupicola. [5] 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. [6] [2]
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. [6]: 301 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. [7]
Yellow button is endemic to Queensland and grows on rocky coastlines, road verges, woodland and exposed ridges. [4] [6]: 306
