Stenanthemum Arens
''Stenanthemum arens'' is a species of flowering plant in the family Rhamnaceae and is endemic to South Australia. It is a twiggy shrub with broadly egg-shaped to almost circular leaves and heads of 10 to 20 silky-hairy white, tube-shaped flowers, usually with whitish floral leaves. Description ''Stenanthemum arens'' is a twiggy shrub, its young stems covered with soft or shaggy, greyish or rust-coloured hairs. Its leaves are broadly egg-shaped with the narrower end toards the base, or almost round, long and wide on a petiole long, with narrowly triangular to linear stipules long at the base. Both surfaces of the leaves are covered with greyish, star-shaped hairs. The leaves are often folded lengthwise. The flowers are borne in groups of 10 to 20 up to wide with bracts long and surrounded by whitish flower leaves. Each flower is on a shaggy-hair pedicel up to long. The floral tube is long and wide, the sepals long and the petals long. Flowering has been observed in J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhamnaceae
The Rhamnaceae are a large family of flowering plants, mostly trees, shrubs, and some vines, commonly called the buckthorn family. Rhamnaceae is included in the order Rosales. The family contains about 55 genera and 950 species. The Rhamnaceae have a worldwide distribution, but are more common in the subtropical and tropical regions. The earliest fossil evidence of Rhamnaceae is from the Late Cretaceous. Fossil flowers have been collected from the Upper Cretaceous of Mexico and the Paleocene of Argentina. Leaves of family Rhamnaceae members are simple, i.e., the leaf blades are not divided into smaller leaflets.Flowering Plants of the Santa Monica Mountains, Nancy Dale, 2nd Ed. 2000, p. 166 Leaves can be either alternate or opposite. Stipules are present. These leaves are modified into spines in many genera, in some (e.g. '' Paliurus spina-christi'' and ''Colletia cruciata'') spectacularly so. ''Colletia'' stands out by having two axillary buds instead of one, one developing i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Journal Of The Adelaide Botanic Gardens
The Adelaide Botanic Garden is a public garden at the north-east corner of the Adelaide city centre, in the Adelaide Park Lands. It encompasses a fenced garden on North Terrace (between Lot Fourteen, the site of the old Royal Adelaide Hospital, and the National Wine Centre) and behind it the Botanic Park (adjacent to the Adelaide Zoo). Work was begun on the site in 1855, with its official opening to the public on 4 October 1857. The Adelaide Botanic Garden and adjacent State Herbarium of South Australia, together with the Wittunga Botanic Garden and Mount Lofty Botanic Garden, comprise the ''Botanic Gardens of South Australia'', administered by the Board of the Botanic Gardens and State Herbarium, a state government statutory authority. Early history From the first official survey carried out for the map of Adelaide, Colonel William Light intended for the planned city to have a "botanical garden". To this end, he designated a naturally occurring ait that had formed in the cour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of South Australia
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurman ...

Rosales Of Australia
Rosales () is an order of flowering plants.Peter F. Stevens (2001 onwards). "Rosales". At: Trees At: Angiosperm Phylogeny Website. At: Missouri Botanical Garden Website. (see ''External links'' below) It is sister to a clade consisting of Fagales and Cucurbitales. It contains about 7,700 species, distributed into about 260 genera. Rosales comprise nine families, the type family being the rose family, Rosaceae. The largest of these families are Rosaceae (90/2500) and Urticaceae (54/2600). The order Rosales is divided into three clades that have never been assigned a taxonomic rank. The basal clade consists of the family Rosaceae; another clade consists of four families, including Rhamnaceae; and the third clade consists of the four urticalean families.Douglas E. Soltis, et alii. (28 authors). 2011. "Angiosperm Phylogeny: 17 genes, 640 taxa". ''American Journal of Botany'' 98(4):704-730.

Stenanthemum
''Stenanthemum'' is a genus of flowering plants family Rhamnaceae and is endemic to Australia. Plants in the genus ''Stenanthemum'' are small shrubs usually lacking spines. The leaves are arranged alternately along the branches, simple, usually folded in half lengthwise on a short petiole. The flowers are arranged in dense heads, usually on the ends of branches with bracts at the base of the flowers, and there are sometimes whitish floral leaves. The flowers are bisexual, more or less sessile and have five sepals, five petals and a tube-shaped hypanthium, the petals hooded over the stamens. The fruit is a schizocarp containing spotted or mottled seeds. Taxonomy The genus ''Stenanthemum'' was first formally described in 1858 by Siegfried Reissek in the journal ''Linnaea''. The genus name means "narrow flower". List of species The following is a list of species of ''Stenanthemum'' accepted by the Australian Plant Census as at November 2022: *'' Stenanthemum arens'' (S.A.) *' ...

Gawler Ranges
The Gawler Ranges are a range of stoney hills in South Australia to the north of Eyre Peninsula. The Eyre Highway skirts the south of the ranges. The Gawler Ranges National Park is in the ranges north of Kimba and Wudinna. The ranges are covered by the Gawler Ranges Native Title Claim. History The traditional owners of the Gawler Ranges are the Barngarla, Kokatha and Wirangu peoples, who have inhabited the area for at least 30,000 years and are now known collectively as the Gawler Ranges Aboriginal People. These Aboriginal peoples maintained and used rock holes in the granite rock formations as a water source. The ranges were named by Edward John Eyre after the Governor of South Australia, George Gawler in 1839. This was on one of Eyre's earlier expeditions before his famous crossing of the Nullarbor Plain further west. It was on this expedition that Edward John Eyre made the first recorded sighting of South Australia's floral emblem, the Sturt desert pea, in 1839 duri ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus '' Homo'' and within this genus to the species '' Homo sapiens''. '' Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

South Australia
South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories by area, and second smallest state by population. It has a total of 1.8 million people. Its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital Adelaide, or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 33,233. South Australia shares borders with all of the other mainland states, as well as the Northern Territory; it is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria, and to the south by the Great Australian B ...

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, ...

Hypanthium
In angiosperms, a hypanthium or floral cup is a structure where basal portions of the calyx, the corolla, and the stamens form a cup-shaped tube. It is sometimes called a floral tube, a term that is also used for corolla tube and calyx tube. It often contains the nectaries of the plant. It is present in many plant families, although varies in structural dimensions and appearance. This differentiation between the hypanthium in particular species is useful for identification. Some geometric forms are obconic shapes as in toyon, whereas some are saucer-shaped as in ''Mitella caulescens''. Its presence is diagnostic of many families, including the Rosaceae, Grossulariaceae, and Fabaceae. In some cases, it can be so deep, with such a narrow top, that the flower can appear to have an inferior ovary - the ovary is below the other attached floral parts. The hypanthium is known by different common names in differing species. In the eucalypts, it is referred to as the ''gum nut' ...
