Gnaphalium luteoalbumL. Contents | |
Helichrysum luteoalbum, the Jersey cudweed, [1] is a species of flowering plant in the family Asteraceae.
It is an erect herbaceous biennial up to 70 cm (28 in) tall, branching from the base. Leaves are oblanceolate to lanceolate and covered in hairs like that of the edelweiss. The leaves can survive frozen over in winter. Flowers are cream, yellow, white, or pink. [2] Seeds have a pappus which lets them float over long distances.
This species was first published by Carl Linnaeus in his 1753 Species plantarum , under the name Gnaphalium luteo-album (the orthography was later changed to omit the hyphen). In 1829, Ludwig Reichenbach transferred it to Helichrysum , but this name was not taken up, and the species was retained in Gnaphalium until 1981, when Olive Mary Hilliard and Brian Laurence Burtt transferred it into Pseudognaphalium . [3] [4]
In 2004, an investigation into the phylogenetic relationships of Helichrysum and related genera found this species to have arisen within Helichrysum. As a result of this, Reichenbach's long-forgotten name for this species was resurrected. [5] A later study showed that all the sampled Pseudognaphalium species arose within Helichrysum as did Anaphalis , Achyrocline and Humeocline . [6]
This species is so widely distributed that it is unclear where it is native and where naturalised. In general it is considered naturalised in North and South America, and native to every other continent except Antarctica. [7] It grows in meadows, wastelands, and edges of forests. Its rosettes are occasionally mistaken for edelweiss.
In Vietnam, the plant is used as a food ingredient, such as in the rice cake banh khuc. It has also been used in traditional medicine of the region, as a diuretic, hemostatic, antipyretic, for the treatment of cough, and for pain relief. [8]
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 Greek words ἑλίσσω and χρῡσός.
The Gnaphalieae are a tribe of flowering plants in the family Asteraceae. It is most closely related to the tribes Anthemideae, Astereae, and Calenduleae.
Gnaphalium is a genus of flowering plants in the family Asteraceae, commonly called cudweeds. They are widespread and common in temperate regions, although some are found on tropical mountains or in the subtropical regions of the world.
Cudweed is a common name for several species, and may refer to:
Xerochrysum is a genus of flowering plants native to Australia. It was defined by Russian botanist Nikolai Tzvelev in 1990, preceding Bracteantha which was described the following year. 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.
Asteroideae is a subfamily of the plant family Asteraceae. It contains about 70% of the species of the family. It consists of several tribes, including Astereae, Calenduleae, Eupatorieae, Gnaphalieae, Heliantheae, Senecioneae and Tageteae. Asteroideae contains plants found all over the world, many of which are shrubby. There are about 1,135 genera and 17,200 species within this subfamily; the largest genera by number of species are Helichrysum (500–600) and Artemisia (550).
This is a list of the terrestrial flora of the Houtman Abrolhos. Only vascular plants are listed — there have been some collections of mosses, liverworts and lichens from the Houtman Abrolhos, but no information has been published on these non-vascular groups.
Calomeria is a plant genus in the family Asteraceae.
Anemocarpa is a genus of flowering plants in the family Asteraceae, endemic to Australia.
Acidonia microcarpa is a species of shrub in the plant family Proteaceae. It is the only species in the genus Acidonia. It is endemic to the south coast of the Southwest Botanic Province of Western Australia.
Ozothamnus ferrugineus, commonly known as tree everlasting, is a member of the genus Ozothamnus, of the Asteraceae family - one of the largest families of flowering plants in Australia. Native to the Australian states of New South Wales, Victoria, South Australia, and Tasmania, it forms an erect shrub or small tree between 2 and 3 metres in height.
Argentipallium is a genus of flowering plants in the family Asteraceae. The genus, which is endemic to Australia, was first formally described in 1992 by Paul G. Wilson in the botanical journal Nutsyia.
Pseudognaphalium is a genus of flowering plants in the sunflower family.
Coronidium boormanii is a perennial herbaceous shrub in the family Asteraceae found in Australia. Previously known as Helichrysum boormanii, it was given its new name in 2008.
Coronidium scorpioides, commonly known as the button everlasting, is a perennial herbaceous shrub in the family Asteraceae found in Australia. Previously known as Helichrysum scorpioides, it was placed in the newly described genus Coronidium in 2008.
Sebaea is a genus of annual plants in the family Gentianaceae. Species occur in Africa, Madagascar, India, China, Thailand, Australia and New Zealand. The genus was paraphyletic and has been split in four genera: Exochaenium, Klackenbergia, Lagenias and Sebaeas.str.. Synapomorphies for Sebaea s.str. include the presence of extra stigma along the style and the shape of the testa cells of the seeds.
Ozothamnus cuneifolius, commonly known as wedge-leaf everlasting or wedge everlasting, is a shrub in the family Asteraceae. It is native to forests of the south-east of New South Wales and Gippsland in Victoria in Australia.
Ozothamnus rogersianus, commonly known as Nunniong everlasting, is a shrub in the family Asteraceae. It is endemic to Victoria, Australia.
Argentipallium niveum is a species of flowering plant within the genus, Argentipallium, in the daisy family (Asteraceae). It is endemic to Western Australia.
Ozothamnus occidentalis is a shrub in the family Asteraceae, native to Western Australia.
