Protea Nubigena
''Protea nubigena'', commonly known as cloud sugarbush, is a very rare species of a flowering shrub belonging to the '' Protea'' genus. It is endemic to KwaZulu-Natal, South Africa and is found in the uKhahlamba Basalt Grassland within the Royal Natal National Park, near Mont-Aux-Sources, at an altitude of about in well-drained, humus-rich soil on shaded slopes. Description The plant grows as an erect shrub which is up to high, and blooms from March to April. It is a long-lived species, and survives fires by resprouting from underground boles or rootstocks. The plant is monoecious with both sexes in each flower; the wind-dispersed seeds are not stored on the plant and are released immediately after ripening. It is pollinated by birds. Conservation It is listed as ' critically endangered' on the SANBI red list The South African National Biodiversity Institute (SANBI) is an organisation established in 2004 in terms of the National Environmental Management: Biodiversity ...

Protea
''Protea'' () is a genus of South African flowering plants, also called sugarbushes (Afrikaans: ''suikerbos''). Etymology The genus ''Protea'' was named in 1735 by Carl Linnaeus, possibly after the Greek god Proteus, who could change his form at will, possibly because they have such a wide variety of forms. Linnaeus's genus was formed by merging a number of genera previously published by Herman Boerhaave, although precisely which of Boerhaave's genera were included in Linnaeus's ''Protea'' varied with each of Linnaeus's publications. Taxonomy The family Proteaceae to which ''Protea'' species belong is an ancient one among angiosperms. Evidence from pollen fossils suggests Proteaceae ancestors grew in Gondwana, in the Upper Cretaceous, 75–80 million years ago. The Proteaceae are divided into two subfamilies: the Proteoideae, best represented in southern Africa, and the Grevilleoideae, concentrated in Australia and South America and the other smaller segments of Gondwana that ...

KwaZulu-Natal
KwaZulu-Natal (, also referred to as KZN and known as "the garden province") is a province of South Africa that was created in 1994 when the Zulu bantustan of KwaZulu ("Place of the Zulu" in Zulu) and Natal Province were merged. It is located in the southeast of the country, with a long shoreline on the Indian Ocean and sharing borders with three other provinces and the countries of Mozambique, Eswatini and Lesotho. Its capital is Pietermaritzburg, and its largest city is Durban. It is the second-most populous province in South Africa, with slightly fewer residents than Gauteng. Two areas in KwaZulu-Natal have been declared UNESCO World Heritage Sites: the iSimangaliso Wetland Park and the uKhahlamba Drakensberg Park. These areas are extremely scenic as well as important to the surrounding ecosystems. During the 1830s and early 1840s, the northern part of what is now KwaZulu-Natal was established as the Zulu Kingdom while the southern part was, briefly, the Boer Nata ...

Royal Natal National Park
Royal Natal National Park is a park in KwaZulu-Natal province, South Africa and forms part of the uKhahlamba Drakensberg Park World Heritage Site. Notwithstanding the name, it is actually not a South African National Park managed by the SANParks, but rather a Provincial Park managed by Ezemvelo KZN Wildlife. This park is now included in the Maloti-Drakensberg Transfrontier Conservation Area Peace Park. The Drakensberg Mountains were once the hunting ground of the San people (bushmen). Though the San no longer live in the area, they recorded their exploits in the form of remarkable rock paintings. The main features of the park are the Drakensberg Amphitheatre, a rock wall long by up to high, Mont-Aux-Sources peak where the Orange and Tugela rivers have their source, and the Tugela Falls, the world's highest waterfall. A distinctive rock feature and popular hiking destination in the park is the so-called "Policeman's Helmet". Royal_Natal.jpg, Trail in Royal Natal Nation ...

Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about fiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoecy
Monoecy (; adj. monoecious ) is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. It is a monomorphic sexual system alongside gynomonoecy, andromonoecy and trimonoecy. Monoecy is connected to anemophily. It can prevent self-pollination in an individual flower but cannot prevent self-pollination between male and female flowers on the same plant. Monoecy in angiosperms has been of interest for evolutionary biologists since Charles Darwin. Terminology Monoecious comes from the Greek words for one house. History The term monoecy was first introduced in 1735 by Carl Linnaeus. Darwin noted that the flowers of monoecious species sometimes showed traces of the opposite sex function. Monoecious hemp was first reported in 1929. Occurrence Monoecy is most common in temperate climates and is often associated with inefficient pollinators or wind-pollinated plants. It may be beneficial to reducing pollen-stigma i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollination
Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind. Pollinating agents can be animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species, it can produce hybrid offspring in nature and in plant breeding work. In angiosperms, after the pollen grain (gametophyte) has landed on the stigma, it germinates and develops a pollen tube which grows down the style until it reaches an ovary. Its two gametes travel down the tube to where the gametophyte(s) containing the female gametes are held within the carpel. After entering an ovum cell through the micropyle, one male nucleus fuses with the polar bodies to produce the endosperm tissues, while the other fuses with the ovule to produce the ...

Flora Of KwaZulu-Natal
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 ...
