Astroloba Rubriflora
''Astroloba rubriflora'' is a succulent plant found in the mountainous Karoo area around Robertson, South Africa. It is listed as a Vulnerable species on the IUCN global Red List. Naming and taxonomy It was formerly grouped by some authorities (L.Bolus) as the only species in a separate monotypic genus, ''Poellnitzia'' (named after the botanist Joseph Karl von Poellnitz), on account of its unusual flowers. Its species name, ''rubriflora'' ("red-flowered"), refers to the peculiarly-formed red flowers, which have green tips. The species has also at various times been placed in the genera ''Aloe'', ''Apicra'' and ''Haworthia''. Description This is one of the most unusual of the species in its genus. Its flowers are unlike those of its close relatives in the ''Astroloba'' and ''Haworthia'' genera, and more similar to those of Aloes. They are evolved to be pollinated by sunbirds. The long thin inflorescence has a horizontal raceme and red flowers with green tips, that all twist into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louisa Bolus
Harriet Margaret Louisa Bolus ''Married and maiden names, née'' Kensit (31 July 1877, Burgersdorp – 5 April 1970, Cape Town) was a South African Botany, botanist and taxonomist, and the longtime curator of the Bolus Herbarium, from 1903. Bolus also has the legacy of authoring more land plant species than any other female scientist, in total naming 1,494 species.

Flora Of The Cape Provinces
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. 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 Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Western Cape
The Western Cape is a province of South Africa, situated on the south-western coast of the country. It is the fourth largest of the nine provinces with an area of , and the third most populous, with an estimated 7 million inhabitants in 2020. About two-thirds of these inhabitants live in the metropolitan area of Cape Town, which is also the provincial capital. The Western Cape was created in 1994 from part of the former Cape Province. The two largest cities are Cape Town and George. Geography The Western Cape Province is roughly L-shaped, extending north and east from the Cape of Good Hope, in the southwestern corner of South Africa. It stretches about northwards along the Atlantic coast and about eastwards along the South African south coast (Southern Indian Ocean). It is bordered on the north by the Northern Cape and on the east by the Eastern Cape. The total land area of the province is , about 10.6% of the country's total.

Robertson Karoo
Robertson Karoo is a semi-arid vegetation type, restricted to sections of the Breede River Valley, Western Cape Province, South Africa. It is a subtype of Succulent Karoo (geographically an extension of the "Little Karoo") and is characterised by the dominance of succulent plant species, and by several endemic plants and animals. Location and extent This vegetation type occurs in several large patches within the Breede River Valley, in the Western Cape Province of South Africa. It occurs in the area between Worcester in the north-west, Ashton in the east, and the Riviersonderend mountains in the south. Landscape and climate Robertson Karoo typically consists of low hills and flats covered in small succulent vegetation, usually growing on rocky shale-based soils. The climate is semi-arid due to the region lying in the rainshadow of the large mountain ranges to the south-west, but the rainfall does tend to occur mainly in winter. This vegetation type has a large number of ende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raceme
A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica'') and radish (genus ''Raphanus'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species ''Cimicifuga racemosa''. A compou ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Haworthia
''Haworthia'' is a large genus of small succulent plants endemic to Southern Africa (Mozambique, Namibia, Lesotho, Eswatini and South Africa). Like the aloes, they are members of the subfamily Asphodeloideae and they generally resemble miniature aloes, except in their flowers, which are distinctive in appearance. They are popular garden and container plants. Description and characteristics ''Haworthias'' are small succulent plants, forming rosettes of leaves from to exceptionally in diameter, depending on the species. These rosettes are usually stemless but in some species stems reach up to . The inflorescences of some species may exceed in height. The plants can grow solitary or can be clump-forming. Many species have firm, tough, fleshy leaves, usually dark green in colour, whereas others are softer and contain leaf windows with translucent panels through which sunlight can reach internal photosynthetic tissues. Their flowers are small, and generally white. Though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
