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 ...

Pierreodendron Kerstingii
''Pierreodendron kerstingii'' is a species of tree in the family Simaroubaceae. It is endemic to West Africa and found in Ivory Coast, Ghana, Togo, and Benin. It is sometimes considered synonym of ''Pierreodendron africanum'', which would then be a widespread species distributed south to Angola and east to the Democratic Republic of the Congo. Description and uses It is a large forest tree growing to tall. The flowers are red and ripe fruits are yellow. The bark is used as insecticide and rat poison, and the extract has anti-tumor properties. Habitat and conservation ''Pierreodendron kerstingii'' occurs in heavily exploited, semi-deciduous forests. It is an uncommon species threatened by habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease .... References kerstingii ...

Jean Baptiste Louis Pierre
Jean Baptiste Louis Pierre (23 October 1833 – 30 October 1905), also known as J. B. Louis Pierre, was a French Botany, botanist known for his Asian studies. Early life Pierre was born in Saint-André, Réunion, Saint-André, Réunion, and studied in Paris before working in the botanical gardens of Calcutta, India. Career In 1864 he founded the Saigon Zoo and Botanical Gardens, which he directed until 1877. Afterward, he returned to Paris and lived at 63 rue Monge, near the Paris Herbarium. In 1883, he moved to Charenton, then to Villeneuve-Saint-Georges, then (circa 1893) to Saint-Mandé. Finally, he settled at 18 rue Cuvier in Paris, where he resided until his death. Pierre made many scientific explorations in tropical Asia. His publications include the ''Flore forestière de la Cochinchine'' (1880-1907), an article "Sur les plantes à caoutchouc de l'Indochine" (''Revue des cultures coloniales'', 1903) and the section on Sapotaceae in the ''Notes botaniques'' (1890-18 ...

Simarouba
''Simarouba'' is a genus of trees and shrubs in the family Simaroubaceae, native to the neotropics. It has been grouped in the subtribe Simaroubina along with the '' Simaba'' and ''Quassia'' genera. They have compound leaves, with between 1 and 12 pairs of alternate pinnate leaflets. Their flowers are unisexual, relatively small (around 1 cm long) and arranged in large panicles. Plants are dioecious, bearing only male or female flowers. The individual flowers have between 4 and 6 sepals and petals and between 8 and 12 stamens. The fruit is a carpophore and has up to 5 drupaceous mericarps. In 1944, Adolf Engler and Arthur Cronquist separated the species in the genus, based mainly on the morphology of their flowers, but also using differences in their leaf structure. ''S. amara'', ''S. glauca'' and ''S. versicolor'' are continental tree species and are often confused with each other, particularly in areas where more than one species is present in the flora. ''S. amara'' can b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Quassia
''Quassia'' ( or ) is a plant genus in the family Simaroubaceae. Its size is disputed; some botanists treat it as consisting of only one species, '' Quassia amara'' from tropical South America, while others treat it in a wide circumscription as a pantropical genus containing up to 40 species of trees and shrubs. Taxonomy The genus was first published in Carl Linnaeus's book ''Species Plantarum'' ed. 2. on page 553 in 1762. The genus was named after a former slave from Suriname, Graman Quassi in the eighteenth century. He discovered the medicinal properties of the bark of '' Quassia amara''. In 1962, Dutch botanist Hans Peter Nooteboom (1934–2022) had taken a very broad view of the genus ''Quassia'' and included therein various genera including, ''Hannoa'' , '' Odyendyea'' , '' Pierreodendron'' , '' Samadera'' , '' Simaba'' and '' Simarouba'' . Then in 2007, DNA sequencing, and phylogenetic analyses was carried out on members of the Simaroubaceae family. It found that ge ...

Samadera
''Samadera'' is a genus of four species of plants belonging to the family Simaroubaceae in the order Sapindales. Its range is from eastern Africa through tropical Asia to eastern Australia. Type species: ''Samadera indica'' Gaertn Description Plants in this genus are large or small trees with simple leaves. The flowers are bisexual, produced in axillary or terminal umbels. The calyces (collective name for the sepals) are small, 3-5 partite (divided into parts) and imbricate (overlapping each other). The 3-5 petals are much longer than the calyx, they are coriaceous (leather-like, stiff and tough) and imbricate. The flower disk is large, conical, with 8-10 stamens, including in the corolla, with a small scale at the base. The stigmas are acute and the ovules are solitary and pendulous. The fruit (or seed capsule) consists of 1-5 large dry compressed 1 seeded drupes (stone fruit), each with a narrow unilateral wing.Edmund Gregory Taxonomy It was first published and described b ...

Simaba
''Simaba'' is a genus of flowering plants belonging to the family Simaroubaceae. Its native range stretches from southern tropical America and Trinidad, across to western tropical Africa to Angola then across to western Malesia. It was first published by French botanist Jean Baptiste Christophore Fusée Aublet (1720–1778), in Hist. Pl. Guiane on page 409 in 1775. 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 ''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 independent genera.

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 ...

Plants Described In 1907
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly 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, 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, mosses, lycophytes, ferns, conifers and other gymnosperm ...
