Protea Restionifolia
''Protea restionifolia'', which is also known as the Reed-leaf sugarbush, is a flowering shrub endemic to the Western Cape province of South Africa where it is found from the upper part of the Breede River Valley through the Bot River Valley to Wolseley and the Koue Bokkeveld Mountains. Other vernacular names which have been recorded for this species are grass-leaf sugarbush and restio-leaf erodendrum. In Afrikaans it is known as the ''bruingrondsuikerbos''. Description The shrub forms a dense root-like mat of rhizomes of up to one meter in diameter. This species has evolved to have thin, round reed-like leaves, very similar to the restios it shares its habitat with. ''P. restionifolia'' flowers in spring, blooming from August to October, peaking in September. The plant is monoecious with both sexes in each flower. It is rarely confused with other species in the field, but is similar to ''P. piscina'' and ''P. revoluta''. It can easily be distinguished from these speci ...

Restionaceae
The Restionaceae, also called restiads and restios, are a family of flowering plants native to the Southern Hemisphere; they vary from a few centimeters to 3 meters in height. Following the 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 pollen, the Restionaceae likely originated more than 65 million years ago during the 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 sedges, rushes, and grasses. They have green, photosynthetic stems and leaves that have been reduced to sheaths. Their flowers are extremely small and in sp ...

Renosterveld
Renosterveld is a term used for one of the major plant communities and vegetation types of the Cape Floristic Region (Cape Floral Kingdom) which is located in southwestern and southeastern South Africa, in southernmost Africa. It is an ecoregion of the Mediterranean forests, woodlands, and scrub biome. Etymology Renosterveld directly translated in the Afrikaans language means "rhinoceros-field", a possible reference to the high number of rhinoceroses seen by the Afrikaner settlers at the time. It may also derive its name from the renosterbos (rhinoceros bush – ''Dicerothamnus rhinocerotis''), which is a common species of shrub found here. The dull grey colour of renosterbos is similar to the colour of a rhino's hide. Geology Renosterveld plants grow on rich soil, which makes them more nutritious than typical fynbos plants. Typically, renosterveld is largely confined to fine-grained soils – mainly clays and silts – which are derived from the shales of the Malmesbury and ...

Karoo
The Karoo ( ; from the Afrikaans borrowing of the South Khoekhoe Khoemana (also known as !Orakobab or Korana) word is a semidesert natural region of South Africa. No exact definition of what constitutes the Karoo is available, so its extent is also not precisely defined. The Karoo is partly defined by its topography, Karoo Supergroup, geology and climate, and above all, its low rainfall, arid air, cloudless skies, and extremes of heat and cold. The Karoo also hosted a well-preserved ecosystem hundreds of millions of years ago which is now represented by many fossils. The Karoo formed an almost impenetrable barrier to the interior from Cape Town, and the early adventurers, explorers, hunters, and travelers on the way to the Highveld unanimously denounced it as a frightening place of great heat, great frosts, great floods, and great droughts. Today, it is still a place of great heat and frosts, and an annual rainfall of between 50 and 250 mm, though on some of the mountains i ...

Fynbos
Fynbos (; , ) is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. The area is predominantly coastal and mountainous, with a Mediterranean climate. The fynbos ecoregion is within the Mediterranean forests, woodlands, and scrub biome. In fields related to biogeography, fynbos is known for its exceptional degree of biodiversity and endemism, consisting of about 80% (8,500 fynbos) species of the Cape floral kingdom, where nearly 6,000 of them are endemic. The area continues to face severe human-caused threats, but due to the many economic uses of the fynbos, conservation efforts are being made to help restore it. Origin of the term The word '' fynbos'' is often taken literally to mean ''fine bush'', as in Afrikaans '' bos'' means '' bush'', whereas in this instance ''bush'' refers to the type of vegetation. Typical fynbos foliage is ericoid rather than ''fine''. The term in its pre-Afrikaans, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trunk (botany)
Trunks are the Plant stem, stems of woody plants and the main structural element of trees. The woody part of the trunk consists of dead but structurally significant heartwood and living sapwood, which is used for nutrient storage and transport. Separating the wood from the bark is the Vascular cambium, cambium, from which trunks grow in diameter. Bark is divided between the living inner bark (the phloem), which transports sugars, and the outer bark, which is a dead protective layer. The precise Cell (biology), cellular makeup of these components differs between non-flowering plants (gymnosperms) and flowering plants (Flowering plant, angiosperms). A variety of specialised cells facilitate the storage of carbohydrates, water, minerals, and transport of water, minerals, and hormones around the plant. Growth is achieved by Cell division, division of these cells. Vertical growth is generated from the Meristem, apical meristems (stem tips), and horizontal (radial) growth, from the c ...

Protea Scorzoneriifolia
''Protea'' () is a genus of South African flowering plants, also called sugarbushes (Afrikaans: ''suikerbos''). It is the type genus of the Proteaceae family. About 92% of the species occur only in the Cape Floristic Region, a narrow belt of mountainous coastal land from Clanwilliam to Grahamstown, South Africa. Most protea species are found south of the Limpopo River. ''Protea madiensis'' grows in Afromontane enclaves across tropical Africa, from Guinea to Sudan, Mozambique, and Angola. ''Protea afra'' ranges from the Cape region to Uganda and Kenya, including in the chaparral zone of Mount Kenya National Park. The extraordinary richness and diversity of species characteristic of the Cape flora are thought to be caused in part by the diverse landscape, where populations can become isolated from each other and in time develop into separate species. Etymology The genus ''Protea'' was named in 1735 by Carl Linnaeus when he was examining male and female plants of a species now k ...

Protea Scabra
''Protea scabra'', also known as the sandpaper-leaf sugarbush, is a flowering groundcover that belongs to the genus ''Protea''. The plant is endemic to South Africa and is found from the Hottentots Holland Mountains across the Riviersonderend Mountains, the Kleinrivier Mountains and around the town of Caledon to the Swartberg mountains. Other vernacular names which have been recorded for this species are rasp-leaf erodendrum, scab-leaf protea, and scabrous sugarbush. In Afrikaans it is known as the ''skurweblaargrondsuikerbos''. Taxonomy This species was collected as a herbarium specimen by William Roxburgh during a stop at the Cape of Good Hope on the way to India, and was first described by Robert Brown in the 1810 publication ''On the Proteaceae of Jussieu''. Brown states the wealthy merchant George Hibbert grew the species in his private protea collection, although he questions if it were not another new species entirely. Brown also described ''Protea tenuifolia'' from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glabrousness (botany)
Glabrousness () is the technical term for a lack of hair, down, setae, trichomes, or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabrescent''. In the model plant ''Arabidopsis thaliana'', trichome formation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protea Revoluta
''Protea revoluta'', also known as the roll-leaved sugarbush or rolled-leaf sugarbush, is a species of plant which is classified in the genus ''Protea''. ''P. revoluta'' is only found growing in the wild in South Africa, where plants can be found growing between the Cederberg inland on the Atlantic coast and the Witteberg area to the north. In Afrikaans this species is known by the vernacular name of ''gerolde-blaarsuikerbos''. This species was first described according to the modern Linnaean system by the naturalist Robert Brown in his 1810 treatise ''On the Proteaceae of Jussieu''. The plant is a prostrate groundcover and grows flat up to two metres in diameter. The blooming season lasts from November to January. The seeds are stored on the plant in the dry inflorescence. They are usually released one to two years after flowering, and are dispersed to new growing locations by action of the wind. The plant is monoecious with both sexes in each flower. Pollination in this s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
