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 ...

Samadera Indica
''Samadera indica'' (syn. ''Quassia indica''), the bitter wood or Niepa bark tree, is a species of plant in the family Simaroubaceae. It is a shrub or tree and grows primarily in wet tropical regions, from west Africa, through India, then down through Indonesia to Malesia. It is used in folklore medicine in various Asian countries as well to treat various ailments such as malaria, fevers, rheumatism, bruises, skin conditions and others conditions.

Samadera Harmandiana
''Samadera harmandiana'' (syn ''Quassia harmandiana'') is a freshwater mangrove shrub or small tree in the Simaroubaceae family. It is found in Cambodia, Laos and Vietnam. The wood provides firewood. Certain fish eat the poisonous fruit Description This species grows as a shrub or small tree, some tall. The species was placed in the section ''Samadera'' by Noteboom in 1962, along with '' Quassia indica''. The plants of this section have simple leaves with roughly scattered concave glands, mostly on the under surface. The flowers are bisexual, occurring in axillary or terminal inflorescences, either pseudoumbels with peduncles or in racemes. There are 3-5 calyx lobes, these are imbricate in the bud, obtuse and have a concave gland in the centre. There are 3-5 contorted petals, much longer than the calyx, usually hairy on the underside.

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 ...

Quassia Amara
''Quassia amara'', also known as amargo, bitter-ash, bitterwood, or hombre grande (spanish language, spanish for ''big man'') is a species in the genus ''Quassia'', with some botanists treating it as the sole species in the genus. The genus was named by Carl Linnaeus who named it after the first botanist to describe it: the Surinamese freedman Graman Quassi. ''Q. amara'' is used as insecticide, in traditional medicine and as additive in the food industry. Name, image, harvested organ ''Quassia'' (genus) ''amara'' (species) is an attractive small evergreen shrub or tree from the tropics and belongs to the family ''Simaroubaceae''. ''Q. amara'' was named after Graman Quassi, a healer and botanist who showed Europeans the plant's fever treating uses. The name "amara" means "bitter" in Latin and describes its very bitter taste. ''Q. amara'' contains more than thirty phytochemicals with biological activities in its tissues including the very bitter compound Quassinoid, quassin. There ...

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] |
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.
