Xerochrysum (syn. Bracteantha) is a genus of flowering plants native to Australia. It was defined by Russian botanist Nikolai Tzvelev in 1990, preceding (and taking precedence over) Bracteantha which was described the following year. [1] [2] A 2002 molecular study of the tribe Gnaphalieae has indicated the genus is probably polyphyletic, with X. bracteatum and X. viscosum quite removed from each other. [3]
This genus and its species names were formerly included in Bracteantha and before that in Helichrysum .
As of January 2014 [update] the authoritative Australian Plant Name Index recognises seven formally named species and five accepted species awaiting formal naming, description and publication: [4]
The genus Helichrysum consists of an estimated 600 species of flowering plants in the sunflower family (Asteraceae). The type species is Helichrysum orientale. They often go by the names everlasting, immortelle, and strawflower. The name is derived from the Ancient Greek words ἥλιος and χρῡσός.
Callitris is a genus of coniferous trees in the Cupressaceae. There are 16 recognized species in the genus, of which 13 are native to Australia and the other three native to New Caledonia. Traditionally, the most widely used common name is cypress-pine, a name shared by some species of the closely related genus Actinostrobus.
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.
Eriocaulon is a genus of about 400 species commonly known as pipeworts, of monocotyledonous flowering plants in the family Eriocaulaceae.
Olearia, most commonly known as daisy-bush, is a genus of flowering plants belonging to the family Asteraceae, the largest of the flowering plant families in the world. Olearia are found in Australia, New Guinea and New Zealand. The genus includes herbaceous plants, shrubs and small trees. The latter are unusual among the Asteraceae and are called tree daisies in New Zealand. All bear the familiar daisy-like composite flowerheads in white, pink, mauve or purple.
Pomaderris is a genus of about 80 species of flowering plants in the family Rhamnaceae, the species native to Australia and/or New Zealand. Plants in the genus Pomaderris are usually shrubs, sometimes small trees with simple leaves arranged alternately along the branches and bisexual, woolly-hairy flowers arranged in racemes or panicles. The flowers are usually yellow and often lack petals.
Dillwynia is a genus of about 20 species of flowering plants in the family Fabaceae, and is endemic to Australia. Plants in this genus are shrubs with simple leaves and yellow or red and yellow flowers similar to others in the family.
Cassinia is a genus of about fifty-two species of flowering plants in the family Asteraceae that are native to Australia and New Zealand. Plants in the genus Cassinia are shrubs, sometimes small trees with leaves arranged alternately, and heads of white, cream-coloured, yellow or pinkish flowers surrounded by several rows of bracts.
Randall James Bayer is an American systematic botanist born in Buffalo, New York, who spent his childhood in East Aurora. He earned a B.Sc. with major in plant breeding and minor in horticulture in 1978 from Cornell University; an M.Sc. in systematic botany in 1980 from the Ohio State University; and a Ph.D. in 1984 from the Ohio State University with the dissertation Evolutionary Investigations in Antennaria. His interest in the genus Antennaria was inspired by noted evolutionary botanist George Ledyard Stebbins (1906–2000) who was a visiting professor at the Ohio State University in 1978–1979.
Hovea is a genus of about forty species of flowering plants in the family Fabaceae, and is endemic to Australia. Plants in this genus are sub-shrubs, shrubs or small trees with simple leaves and purple, blue or mauve flowers with a white centre. The fruit is a pod containing brown to blackish seeds. Species of Hovea occur in all Australian states, the Australian Capital Territory and the Northern Territory.
Xanthosia is a genus of flowering plants in the family Apiaceae and is endemic to Australia. It comprises 20 species of shrubs endemic to Australia. Plants in the genus Xanthosia are perennial herbs or small shrubs, the leaves divided, toothed or lobed,, the flowers white, pinkish or pale green and usually arranged in a compound umbel.
Goodia is a genus of six species of flowering plants in the family Fabaceae, and is endemic to Australia. Plants in the genus Goodia are shrubs with trifoliate leaves. The flowers are arranged in racemes, the sepals with two "lips", the standard petal more or less circular and the fruit is a flattened pod.
Lasiopetalum, commonly known as velvet bushes, is a genus of about forty-five species of flowering plants in the family Malvaceae, all endemic to Australia.
Daviesia, commonly known as bitter-peas, is a genus of about 130 species of flowering plants in the family Fabaceae, and is endemic to Australia. Plants in the genus Daviesia are shrubs or small trees with leaves modified as phyllodes or reduced to scales. The flowers are arranged singly or in groups, usually in leaf axils, the sepals joined at the base with five teeth, the petals usually yellowish with reddish markings and the fruit a pod.
Xerochrysum viscosum is a flowering plant in the family Asteraceae. The plant is native to Australia, occurring in Queensland, New South Wales, Victoria, Tasmania and the Australian Capital Territory
Xerochrysum subundulatum is a flowering plant in the family Asteraceae, native to Australia, growing in Victoria, New South Wales and Tasmania.
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 40 cm 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.
Vittadinia is a genus of Australian and New Zealand plants in the tribe Astereae within the family Asteraceae.
Asteridea is a genus of flowering plants in the family Asteraceae. Evidence suggests that the genus, Asteridea, is monophyletic.
Xerochrysum bicolor is a flowering plant in the family Asteraceae, native to Tasmania, where it is found in wetter habitats near the coast. It was originally described by Lindley in 1835 as Helichrysum bicolor, before gaining its current name in 2001.
