Spyridium Coactilifolium
''Spyridium coactilifolium'', commonly known as butterfly spyridium, is a species of flowering plant in the family Rhamnaceae. It has white-velvety flowers and oval shaped leaves that are thickly covered in soft hairs. Description ''Spyridium coactilifolium'' is a small perennial shrub with rusty-coloured short, matted, dense hairs on the branches. The leaves are oval to egg-shaped, rounded at the base, blunt and notched at the apex, long and densely covered with soft, star-shaped hairs. The flower petals are velvety-white, usually 4 or 5, entire or notched at the apex and about long. The bracts are silky, brown, and egg-shaped with small hairs on the margins. Flowering occurs from December to February and the fruit is a brown capsule, egg-shaped with the narrower end at the base, hard, thin, brittle, smooth except near the base. Taxonomy and naming ''Spyridium coactilifolium'' was first formally described in 1858 by Siegfried Reisseck and the description was published in '' ...

Siegfried Reisseck
Siegfried Reissek (11 April 1819 in Teschen – 9 November 1871 in Vienna) was an Austrian naturalist and botanist who specialized in spermatophytes. He is known for his studies involving plant anatomy and histology. From 1837 to 1841 he was a student at the University of Vienna. He worked as assistant curator at the Royal Botanical Collection in Vienna between 1845 and 1867, when he was appointed head curator; and from 1848 was a member of the Vienna Academy of Sciences. He circumscribed numerous plant taxa, including the genus ''Stenanthemum'' (family Rhamnaceae). The plant genus ''Reissekia'' from Brazil (in the family Rhamnaceae) commemorates his name.

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 int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bract
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Encounter Bay
Encounter Bay is a bay in the Australian state of South Australia located on the state's south central coast about south of the state capital of Adelaide. It was named by Matthew Flinders after his encounter on 8 April 1802 with Nicolas Baudin, the commander of the Baudin expedition of 1800–03. It is the site of both the mouth of the River Murray and the regional city of Victor Harbor. It is one of four "historic bays" located on the South Australian coast. Extent There are at least two definitions of the bay’s extent: *Firstly, the US National Geospatial-Intelligence Agency states that Newland Head is its westerly extremity while the mouth of the River Murray is the easterly extremity. *Secondly, Australian authorities consider the bay’s extent consists of all of the sea north of a line running east from the southern tip of Rosetta Head to the Younghusband Peninsula. Encounter Bay is one of four bays on the South Australian coast considered by the Australian go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fleurieu Peninsula
The Fleurieu Peninsula () is a peninsula in the Australian state of South Australia located south of the state capital of Adelaide. History Before British colonisation of South Australia, the western side of the peninsula was occupied by the Kaurna people, while several clans of the Ngarrindjeri lived on the eastern side. The people were sustained by the flora and fauna of the peninsula, for food and bush medicine. The bulrushes, reeds and sedges were used for basket-weaving or making rope, trees provided wood for spears, and stones were fashioned into tools. The Fleurieu Peninsula was named after Charles Pierre Claret de Fleurieu, the French explorer and hydrographer, by the French explorer Nicolas Baudin as he explored the south coast of Australia in 1802. The name came into official use in 1911 after Fleurieu's great-nephew, Count Alphonse de Fleurieu, visited Adelaide and met with the Council of the Royal Geographical Society of South Australia, which recommended to t ...

National Parks And Wildlife Act 1972
Protected areas of South Australia consists of protected areas located within South Australia and its immediate onshore waters and which are managed by South Australian Government agencies. As of March 2018, South Australia contains 359 separate protected areas declared under the ''National Parks and Wildlife Act 1972'', the ''Crown Land Management Act 2009'' and the ''Wilderness Protection Act 1992'' which have a total land area of or 21.5% of the state's area. Jurisdiction The jurisdiction for legislation of protected areas within South Australia and the immediate onshore waters known officially as ‘the coastal waters and waters within the limits of South Australia' belongs to the South Australian government. The major piece of legislation concerned with the creation and the subsequent management of protected areas is the ''National Parks and Wildlife Act 1972''. Protected areas created by this Act form the majority of South Australia’s contribution to the National Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spyridium
''Spyridium'' is a genus of about thirty species of flowering plants in the family Rhamnaceae, and is endemic to Australia. Plants in the genus ''Spyridium'' are shrubs or subshrubs usually with small leaves, flowers usually in clusters of small composite heads, the individual flowers small and densely woolly-hairy, and the fruit a capsule. Species of ''Spyridium'' are found in all Australian states except Queensland. Description Plants in the genus ''Spyridium'' are shrubs or subshrubs, usually less than tall and have hairy branchlets. The leaves are arranged alternately along the branches and are usually small, with papery brown stipules at the base. The flowers are small, bisexual, densely white woolly-hairy, sessile and usually borne in small composite heads with small brown bracts at the base, the heads themselves usually clustered in a corymbose cyme. There are five sepals, five petals and three carpels, and the fruit is a capsule with the remains of the sepals attac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
