Leucospermum Muirii
''Leucospermum muirii'' is a rounded, upright, evergreen shrub of about high, with a single trunk at its base, that is assigned to the Proteaceae. The flowering branches are thick and are initially grey due to a covering of fine crinkly hairs, which are soon lost. The very narrow spade-shaped leaves of about long and wide carry three to seven teeth, and also quickly lose their soft layer of hairs. Its smallish globe-shaped flower heads of in diameter occur with one to four together, each on a stalk of long. It has pale to greenish yellow flowers, becoming orange with age, with some long hairs near their tips, from which straight styles stick out. This gives the flower head the likeness of a pincushion. It flowers from July till October and is pollinated by birds. It is called Albertinia pincushion in English and bloukoolhout in Afrikaans. It is an endemic species that can only be found near Albertinia in the very south of the Western Cape province of South Africa. Desc ...

Diploid
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle.

Wildfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of Combustibility and flammability, combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire(bushfires in Australia, in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Fire ecology, Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burn, controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurre ...

Protea Repens
''Protea repens'', known as the common sugarbush and in Afrikaans as the suikerbossie, is an erect shrub growing in the southern regions of South Africa. Related to other proteas, this plant is a relatively adaptable and variable species and can be found growing widely in various soils. Due to its showy flowers and adaptability, it is a popular garden subject for use in wildlife gardens in South Africa. Etymology The name of the plant family Proteaceae as well as the genus ''Protea'', both to which ''P. repens'' belongs to, derive from the name of the Greek god Proteus, a deity that was able to change between many forms. This is an appropriate image, seeing as both the family and the genus are known for their astonishing variety and diversity of flowers and leaves. The specific epithet ''repens'' means 'creeping', a case of mistaken identity, where Linnaeus used two different illustrated plates to describe the species: one was of ''P. repens'', and the other showed a dwarf creep ...

Leucospermum Praecox
''Leucospermum praecox'' is an evergreen, rounded, upright shrub of up to 3 m (9 ft) high, and 4 m (12 ft) in diameter that is assigned to the family Proteaceae. It has hairless, inverted egg-shaped to broadly wedge-shaped leaves of about 5 cm (2 in) long with six to eleven teeth near the tip, globe-shaped flower head with initially yellow flowers, later orange or scarlet, with styles sticking far out, giving the head the appearance of a pincushion. It is called Mossel Bay pincushion or large-tufted pincushion in English. It flowers between April and September. It is an Endemism, endemic species that is restricted to the very south of the Western Cape province of South Africa. Description The Mossel Bay pincushion is an upright, rounded shrub of 2–3 m (6–9 ft) high and up to 4 m (12 ft) in diameter that has a stout main stem of up to 8 cm (3.2 in) in diameter. The branches are covered by a smooth, grey bark. The flowerin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leucadendron Galpinii
''Leucadendron'' is a genus of about 80 species of flowering plants in the family Proteaceae, endemic (ecology), endemic to South Africa, where they are a prominent part of the fynbos ecoregion and vegetation type. Description Species in the genus ''Leucadendron'' are small trees or shrubs that are erect or creeping. Most species are shrubs that grow up to 1 m tall, some to 2 or 3 m. A few grow into moderate-sized trees up to 16 m tall. All are evergreen. The leaf, leaves are largely elliptical, sometimes needle-like, spirally arranged, simple, entire, and usually green, often covered with a waxy bloom, and in the case of the Silvertree, with a distinct silvery tone produced by dense, straight, silky hairs. This inspired the generic name ''Leucadendron'', which literally means "white tree". The flowers are produced in dense inflorescences at the branch tips; plants are plant sexuality, dioecious, with separate male and female plants. The seed heads, or infructescences, of ''Leu ...

Restionaceae
The Restionaceae, also called restiads and restios, are a family (biology), family of flowering plants native to the Southern Hemisphere; they vary from a few centimeters to 3 meters in height. Following the APG IV system, APG IV (2016): the family now includes the former families Anarthriaceae, Centrolepidaceae and Lyginiaceae, and as such includes 51 genera with 572 known species. Based on evidence from fossil pollens, the Restionaceae likely originated more than 65 million years ago during the Cretaceous, Late Cretaceous period, when the southern continents were still part of Gondwana.Bremer, K. (2002). "Gondwanan Evolution of the Grass Alliance of Families (Poales)." ''Evolution'', 56(7): 1374-1387 Description The family consists of tufted or rhizomatous, herbaceous plants belonging to a group of monocotyledons that includes several similar families, such as the Cyperaceae, sedges, Juncaceae, rushes, and Poaceae, grasses. They have green, photosynthetic stems and leaves that h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ericaceae
The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with c.4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers (''Erica'', ''Cassiope'', ''Daboecia'', and ''Calluna'' for example). Description The Ericaceae contain a morphologically diverse range of taxa, including herbs, dwarf shrubs, shrubs, and trees. Their leaves are usually evergreen, alternate or whorled, simple and without stipules. Their flowers are hermaphrodite and show considerable variability. The petals are often fused (sympetalous) with shapes ranging from narrowly tubular to funnelform or widely urn-shaped. The corollas are usually ra ...

Gouritsmond
Gouritsmond is a small South African tourist town in the municipality of Hessequa, Garden Route District, Western Cape Province. It is situated about 36 road kilometres south-east of Albertinia. Gouritsmond is located just on the west side of the Gouritz River estuary and on the Indian Ocean. In 2011, Gouritsmond had 515 inhabitants in 206 households. Description The landscape surrounding the village is a section of the coastal plains of the Cape and is characterised by overgrown sand dunes. Its name is derived from the mouth of the Gouritz River, which flows into the ocean here. As an official administrative settlement, Gouritsmond is a young settlement, although European immigrants have been farming in the area since 1730. In the process, the present settlement area was a fishing ground and was therefore called The Fisheries. Gouritsmond was granted town status in 1915 and changed its name to Gouritzriviermond between 1915 and 1966 and finally to the current version. Landmar ...

Still Bay
The Stillbay (also Still bay) industry is the name given by archaeologists A. J. H. Goodwin and C. van Riet Lowe in 1929 to a Middle Stone Age stone tool manufacturing style after the site of Stilbaai (also called Still Bay) in South Africa where it was first described. It may have developed from the earlier Acheulian types. In addition to Acheulian stone tools, bone and antler picks were also used. Its start and end are calculated at 71.9 ka and 71.0 ka. At present, too few data exist to limit the 95% confidence intervals of these date to more than 4 to 5 ky. However, available data are consistent with a duration of less than 1 ky. Sampson in 1974 questioned its existence on the grounds that sites were not properly described and they lacked stratigraphic integrity However, more recent work from sites such as Blombos Cave and Sibudu Cave attest to its existence. It is broadly analogous to the Mousterian culture in Europe. Olduvai Gorge has within its many ages of tools, some o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leucospermum
''Leucospermum'' is a genus of evergreen upright, sometimes creeping shrubs that is assigned to the Proteaceae, with currently forty-eight known species. Almost all species are easily recognised as ''Leucospermum'' because of the long protruding styles with a thickened pollen-presenter, which jointly give the flower head the appearance of a pincushion, its common name. Pincushions can be found in South Africa, Swaziland, Zimbabwe and Mozambique. The shrubs mostly have a single stem at their base, but some species sprout from an underground rootstock, from which the plant can regrow after fire has killed the above ground biomass. In a larger group of species, specimens are killed by fire, and their survival depends on the seeds. In all species, seeds are collected by ants, which take them to their underground nests to feed on their ant breads, a seed dispersal strategy known as myrmecochory. This ensures that the seeds do not burn, so new plants can grow from them. ''Leucospermum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Section (botany)
In botany, a section ( la, sectio) is a taxonomic rank below the genus, but above the species. The subgenus, if present, is higher than the section, and the rank of series, if present, is below the section. Sections may in turn be divided into subsections.Article 4 in Sections are typically used to help organise very large genera, which may have hundreds of species. A botanist wanting to distinguish groups of species may prefer to create a taxon at the rank of section or series to avoid making new combinations, i.e. many new binomial names for the species involved. Examples: * ''Lilium'' sectio ''Martagon'' Rchb. are the Turks' cap lilies * ''Plagiochila aerea'' Taylor is the type species of ''Plagiochila'' sect. ''Bursatae'' See also * Section (biology) References Section Section, Sectioning or Sectioned may refer to: Arts, entertainment and media * Section (music), a complete, but not independent, musical idea * Section (typography), a subdivision, especially ...
