Penaea
''Penaea'' is a genus of flowering plants in the family Penaeaceae, found in southern South Africa. They have an unusual type of embryo sac development; after two rounds of mitosis, four nuclei are formed at each pole, leading to a mature embryo sac containing four polar groups each with three cells. When found in other taxa, these embryo sacs are termed ''Penaea''-type. Species Currently accepted species include: *''Penaea acuta'' Thunb. *'' Penaea acutifolia'' A.Juss. *'' Penaea candolleana'' Stephens *'' Penaea cneorum'' Meerb. *'' Penaea dahlgrenii'' Rourke *'' Penaea dubia'' Stephens *'' Penaea ericifolia'' (A.Juss.)

Rhynchocalyx
''Rhynchocalyx lawsonioides'' is a small flowering tree, the sole species of the genus ''Rhynchocalyx''. It had also previously been regarded as the only species in the monogeneric family Rhynchocalycaceae but is now included in the expanded Penaeaceae along with ''Olinia'' (formerly of the Oliniaceae) under the APG III system of classification. ''Rhynchocalyx'' is endemic to the KwaZulu-Cape coastal forest mosaic ecoregion of the Natal and Eastern Cape provinces of 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 countri .... References Schönenberger, J. and Conti, E., 2003.

Olinia
''Olinia'' is a genus of small trees and shrubs with 10 species in the family Penaeaceae. The species of ''Olinia'' are native to Africa, ranging from west Africa to South Africa. It was previously regarded as the sole genus in the family Oliniaceae, but is now included in the expanded Penaeaceae along with ''Rhynchocalyx'' (formerly of the Rhynchocalycaceae) under the APG III system The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG).

APG III System
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families followi ...

Robert Sweet (botanist)
Robert Sweet (1783–20 January 1835) was an English botanist, horticulturist and ornithologist. Born at Cockington near Torquay, Devonshire, England in 1783, Sweet worked as a gardener from the age of sixteen, and became foreman or partner in a series of nurseries. He was associated with nurseries at Stockwell, Fulham and Chelsea. In 1812 he joined Colvills, the famous Chelsea nursery, and was elected a fellow of the Linnean Society. By 1818 he was publishing horticultural and botanical works. He published a number of illustrated works on plants cultivated in British gardens and hothouses. The plates were mainly drawn by Edwin Dalton Smith (1800–1883), a botanical artist, who was attached to the Royal Botanic Gardens, Kew. His works include ''Hortus Suburbanus Londinensis'' (1818), ''Geraniaceae'' (five volumes) (1820–30), ''Cistineae'', ''Sweet's Hortus Britannicus'' (1826–27), '' Flora Australasica'' (1827–28) and ''British Botany'' (with H. Weddell) (1831). He di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Baptiste Antoine Guillemin
Jean Baptiste Antoine Guillemin (20 January 1796 in Pouilly-sur-Saône – 15 January 1842 in Montpellier) was a French botanist. He studied at the municipal college in Seurre, where he was considered one of the most distinguished pupils. Upon leaving school he was placed with a lawyer. He worked there for eighteen months, but his interest in chemistry and desire to obtain a commission as a military pharmacist, at a time when it was difficult to avoid conscription, caused him to abandon the study of law. In 1812, he was apprenticed to a pharmacist in Dijon. After two years in that city, he went to Geneva, where he studied with Jean Pierre Étienne Vaucher (1763–1841) and Augustin Pyramus de Candolle (1778–1841). One day, while collecting plants in the Alps, he fell and broke his right arm. The injury was slow to heal, and the accident left him with permanent stiffness in the elbow joint. In 1820 he relocated to Paris, where he became curator of the herbarium and library o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
