Description

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]

Taxonomy

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]

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. [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]

Distribution and habitat

Yellow button is endemic to Queensland and grows on rocky coastlines, road verges, woodland and exposed ridges. [4] [6] :306

<i>Xerochrysum bracteatum</i> Flowering plant in the family Asteraceae native to Australia

Xerochrysum bracteatum, commonly known as the golden everlasting or strawflower, is a flowering plant in the family Asteraceae native to Australia. Described by Étienne Pierre Ventenat in 1803, it was known as Helichrysum bracteatum for many years before being transferred to a new genus Xerochrysum in 1990. It is an annual up to 1 m (3.3 ft) tall with green or grey leafy foliage. Golden yellow or white flower heads are produced from spring to autumn; their distinctive feature is the papery bracts that resemble petals. The species is widespread, growing in a variety of habitats across the country, from rainforest margins to deserts and subalpine areas. The golden everlasting serves as food for various larvae of lepidopterans, and adult butterflies, hoverflies, native bees, small beetles, and grasshoppers visit the flower heads.

<i>Chrysocephalum semipapposum</i> Species of plant

Chrysocephalum semipapposum, commonly known as clustered everlasting is a perennial shrub native to Australia. Clustered everlasting belongs to the family Asteraceae. C. semipapposum produces terminal flowers heads in clusters, mainly between spring and early summer with silver-grey appearing stems and branches. It grows up to 40cm high and 60 cm high, although there have been some varieties which can grow up to 1 m. C. semipapposum is often confused with Chrysocephalum apiculatum or 'yellow buttons', due to their similar appearances. C. semipapposum has 4 different subspecies, however they lack distinctive qualities and are often hard to identify. C. semipapposum is endemic to Australia and can be found in multiple states, most notably within Victoria. The plant is found in a variety of habitats including dry rocky regions. Clustered everlasting often grows sparsely and is rarely found in abundance and can be mistaken for a weed. Clustered everlasting has many uses, including as a source of nectar for butterflies, cut flowers or as an addition to a garden.
