Letestua
''Letestua'' is a monotypic genus of plants in the family Sapotaceae, described as a genus in 1917. The genus name of ''Letestua'' is in honour of Georges Marie Patrice Charles Le Testu (1877–1967), who was a French colonial administrator in tropical Africa and later worked at a botanical garden in Caen. There is only one recognized species, ''Letestua durissima''. It is native to Gabon Gabon ( ; ), officially the Gabonese Republic (), is a country on the Atlantic coast of Central Africa, on the equator, bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo to the east and south, and ... and West Congo.

Sapotoideae
The Sapotoideae are a subfamily of the flowering plant family Sapotaceae. Plants in the subfamily are characterized by their leather-like leaves, often growing in a stipule fashion. The seeds of the tree ''Argania spinosa'' produce an edible oil, traditionally harvested in Morocco.

Paul Henri Lecomte
Paul Henri Lecomte (8 January 1856, in Saint-Nabord, Vosges – 12 June 1934, in Paris) was a French botanist. In 1884, after attaining a number of degrees, Lecomte became a professor at Lycée Saint-Louis in Paris. In addition to his teaching duties, he worked in the botany laboratory of the ''Muséum national d'histoire naturelle'' ( French National Museum of Natural History) under Philippe van Tieghem. Lecomte obtained his doctorate in 1889 and subsequently took part in scientific expeditions to North Africa, Egypt, the Antilles, French Guiana and French Indo-China. In 1906, after having volunteered his time for some twenty years at the Muséum national d'histoire naturelle, Lecomte was formally appointed to head the spermatophyte department, a paid position, succeeding Louis Édouard Bureau. In 1917, he was elected a member of the French Academy of Sciences The French Academy of Sciences (, ) is a learned society, founded in 1666 by Louis XIV at the suggestion of J ...

Auguste Chevalier
Auguste Jean Baptiste Chevalier (June 1873, in Domfront – June 1956, in Paris) was a French botanist, taxonomist, and explorer of tropical Africa, especially of French colonial empire in Africa that included Côte d'Ivoire. He also explored and collected plants in South America and tropical Asia. Chevalier was a prolific contributor to the knowledge of African plants, studying forest trees and their woods, grasses, and agricultural plants of the continent. Unlike other botanists who studied the plants of tropical Africa, Chevalier also ranged to the floral regions of the Sahara. In 1896, he obtained his degree in natural sciences and in 1901 his phD from the University of Lille.Prosopo Sociétés savantesJSTOR Global ...

Pierreodendron
''Pierreodendron'' is a genus of plants in the family Simaroubaceae. Its native range is western tropical Africa and is found in Angola, Benin, Cameroon, Congo, Gabon, Ghana, Ivory Coast, Liberia, Nigeria, Togo and Zaïre. It was first published by German botanist Adolf Engler in Bot. Jahrb. Syst. vol.39 on page 575 in 1907. The genus name of ''Pierreodendron'' is in honour of Jean Baptiste Louis Pierre (1833–1905), a French botanist known for his Asian studies, as well as ''dendron'' the Greek word for tree. Hans Peter Nooteboom (1934–2022) in 1962 (published in 1963), took a very broad view of the genus ''Quassia'' and included therein various genera including, ''Hannoa'' , '' Odyendyea'' , ''Pierreodendron'' , '' Samadera'' , '' Simaba'' and also '' Simarouba'' In 2007, molecular analyses of the Simaroubaceae family (Clayton et al., 2007), suggested the splitting up of genera ''Quassia'' again, with all Nooteboom's synonyms listed above being resurrected as independe ...

Simaroubaceae
The Simaroubaceae, also known as the quassia family, are a small, mostly tropical, family in the order Sapindales. In recent decades, it has been subject to much taxonomic debate, with several small families being split off. A molecular phylogeny of the family was published in 2007, greatly clarifying relationships within the family. Together with chemical characteristics such as the occurrence of petroselinic acid in ''Picrasma'', in contrast to other members of the family such as ''Ailanthus'', this indicates the existence of a subgroup in the family with ''Picrasma'', ''Holacantha'', and '' Castela''. The best-known species is the temperate Chinese tree-of-heaven ''Ailanthus altissima'', which has become a cosmopolitan weed tree of urban areas and wildlands. Well-known genera in the family include the tropical ''Quassia'' and '' Simarouba''. It is known in English by the common names of the quassia family or ailanthus family. Genera 20 genera are accepted: *''Ailanthu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of Genus, genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical o ...

Plant
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

West Congo
The Republic of the Congo, also known as Congo-Brazzaville, the Congo Republic or simply the Congo (the last ambiguously also referring to the neighbouring Democratic Republic of the Congo), is a country located on the western coast of Central Africa to the west of the Congo River. It is bordered to the west by Gabon, to the northwest by Cameroon, to the northeast by the Central African Republic, to the southeast by the Democratic Republic of the Congo, to the south by the Angolan exclave of Cabinda, and to the southwest by the Atlantic Ocean. The region was dominated by Bantu-speaking tribes at least 3,000 years ago, who built trade links leading into the Congo River basin. From the 13th century, the present-day territory was dominated by a confederation led by Vungu which included Kakongo and Ngoyo. Loango emerged in the 16th century. In the late 19th century France colonised the region and incorporated it into French Equatorial Africa. The Republic of the Congo was establi ...

Flora Of West-Central Tropical Africa
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. 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) wa ...
