Merwilla
''Merwilla'' is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae (also treated as the family Hyacinthaceae).Stevens, P.F. (2001 onwards),Asparagales: Scilloideae, ''Angiosperm Phylogeny Website'', retrieved 2014-02-25 It is distributed in southern Africa, from Zimbabwe to South Africa.

List of South African plant botanical authors#V Description Species of ''Merwilla'' grow from relatively large bulbs, the upper part of which is usually above ground. The bulbs have light yellow to gray tunics. Plants have broad leaves. The flowers are borne in a raceme. Each flower has six blue tepals, forming a star shape.

Scilloideae
Scilloideae (named after the genus ''Scilla'', "squill") is a subfamily of bulbous plants within the family ''Asparagaceae''. Scilloideae is sometimes treated as a separate family Hyacinthaceae, named after the genus ''Hyacinthus''. Scilloideae or Hyacinthaceae include many familiar garden plants such as ''Hyacinthus'' (hyacinths), ''Hyacinthoides'' (bluebells), ''Muscari'' (grape hyacinths) and ''Scilla'' and ''Puschkinia'' (squills or scillas). Some are important as cut flowers. Scilloideae are distributed mostly in Mediterranean climates, including South Africa, Central Asia and South America. Their flowers have six tepals and six stamens with a superior ovary, which previously placed them within the lily family (Liliaceae), and their leaves are fleshy, mucilaginous, and arranged in a basal rosette. The Scilloideae, like most lily-like monocots, were at one time placed in a very broadly defined lily family (Liliaceae). The subfamily is recognized in modern classification syst ...

Asparagaceae Genera
Asparagaceae, known as the asparagus family, is a family of flowering plants, placed in the order Asparagales of the monocots. The family name is based on the edible garden asparagus, ''Asparagus officinalis''. Those who live in the temperate climates may be surprised to learn that this family includes both common garden plants as well as common houseplants. The garden plants include asparagus, yucca, bluebell, and hosta, and the houseplants include snake plant, corn cane, spider plant and plumosus fern. Taxonomy In earlier classification systems, the species involved were often treated as belonging to the family Liliaceae. The APG II system of 2003 allowed two options as to the circumscription of the family: either Asparagaceae ''sensu lato'' ("in the wider sense") combining seven previously recognized families, or Asparagaceae ''sensu stricto'' ("in the strict sense") consisting of very few genera (notably ''Asparagus'', also ''Hemiphylacus''), but nevertheless totalling ...

Zimbabwe
Zimbabwe (), officially the Republic of Zimbabwe, is a landlocked country located in Southeast Africa, between the Zambezi and Limpopo Rivers, bordered by South Africa to the south, Botswana to the south-west, Zambia to the north, and Mozambique to the east. The capital and largest city is Harare. The second largest city is Bulawayo. A country of roughly 15 million people, Zimbabwe has 16 official languages, with English, Shona language, Shona, and Northern Ndebele language, Ndebele the most common. Beginning in the 9th century, during its late Iron Age, the Bantu peoples, Bantu people (who would become the ethnic Shona people, Shona) built the city-state of Great Zimbabwe which became one of the major African trade centres by the 11th century, controlling the gold, ivory and copper trades with the Swahili coast, which were connected to Arab and Indian states. By the mid 15th century, the city-state had been abandoned. From there, the Kingdom of Zimbabwe was established, fol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively. The largest city is Johannesburg. About 80% of the population are Black South Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Botanic Gardens, Kew
Royal Botanic Gardens, Kew is a non-departmental public body in the United Kingdom sponsored by the Department for Environment, Food and Rural Affairs. An internationally important botanical research and education institution, it employs 1,100 staff. Its board of trustees is chaired by Dame Amelia Fawcett. The organisation manages botanic gardens at Kew in Richmond upon Thames in south-west London, and at Wakehurst, a National Trust property in Sussex which is home to the internationally important Millennium Seed Bank, whose scientists work with partner organisations in more than 95 countries. Kew, jointly with the Forestry Commission, founded Bedgebury National Pinetum in Kent in 1923, specialising in growing conifers. In 1994, the Castle Howard Arboretum Trust, which runs the Yorkshire Arboretum, was formed as a partnership between Kew and the Castle Howard Estate. In 2019, the organisation had 2,316,699 public visitors at Kew, and 312,813 at Wakehurst. Its site at Kew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of South African Plant Botanical Authors
List of authors of South African botanical taxa is a list of authors who have named South African plants and the standard abbreviations used for those authors in the botanical literature. The entry for each author is given on a single line showing their name, dates and other names by which they have been known. Following this comes a list of the major groups they have worked on, separated by commas, and finally the standard form for their name (in bold). The major groups are *S - Spermatophytes/Phanerogams (flowering plants and gymnosperms) *M - Fungi and Lichens (Mycology) *A - Algae *P - Pteridophytes *B - Bryophytes *F - Fossils *L - Pre-Linnaean taxonomy, Linnaean (from ') *C - Cryptogamic (from ') The dates given are those of birth and death where one or both are available. If neither is known, a date on which the author is known to have published a name (usually the earliest if more than one is known) is given preceded by 'fl.' (''floruit'').

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Tepal
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, '' Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...
