Aizoaceae
The Aizoaceae, or fig-marigold family, is a large family of dicotyledonous flowering plants containing 135 genera and about 1800 species. They are commonly known as ice plants or carpet weeds. They are often called vygies in South Africa and New Zealand. Highly succulent species that resemble stones are sometimes called mesembs. Description The family Aizoaceae is widely recognised by taxonomists. It once went by the botanical name "Ficoidaceae", now disallowed. The APG II system of 2003 (unchanged from the APG system of 1998) also recognizes the family, and assigns it to the order Caryophyllales in the clade core eudicots. The APG II system also classes the former families Mesembryanthemaceae Fenzl, Sesuviaceae Horan. and Tetragoniaceae Link under the family Aizoaceae. The common Afrikaans name "vygie" meaning "small fig" refers to the fruiting capsule, which resembles the true fig. Glistening epidermal bladder cells give the family its common name "ice plants".

Harriet Margaret Louisa Bolus
Harriet Margaret Louisa Bolus '' née'' Kensit (31 July 1877, Burgersdorp – 5 April 1970, Cape Town) was a South African 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. Early life and education Bolus was born in Burgersdorp, Cape Province, South Africa, on 31 July 1877. She was the daughter of William Kensit and Jane Stuart Kensit. Her parents were both British-born. Her grandfather William Kensit was a serious amateur botanist and specimen collector in South Africa. She attended Collegiate Girls' High School in Port Elizabeth, earned a teaching credential in 1899, and was awarded a BA degree in literature and philosophy by the University of the Cape of Good Hope in 1902. Career She worked as an assistant to her great-aunt Sophia's husband Harry Bolus in his herbarium while she was in college. In June 1913 she ...

Heidrun Hartmann
Heidrun Hartmann, née Heidrun Elsbeth Klara Osterwald (born 5 August 1942 Kolberg; died 11 July 2016) was a German botanist. She worked at the University of Hamburg and specialised in Aizoaceae, Crassulaceae The Crassulaceae (from Latin ''crassus'', thick), also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crass ..., collected plants from Africa and South America. She was honoured in 1995 when botanist Steven Allen Hammer published '' Hartmanthus'' an African genus of tropical, succulent flowering plants in the family Aizoaceae.

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Louisa Bolus
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Described In 1992
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...
