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 ...

Quassia Amara13
''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 genus ''Sam ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Flower
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants ( angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same f ...

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.

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 ...

Pierreodendron
''Pierreodendron'' is a genus of plants in the family Simaroubaceae.

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 ...

Hans Peter Nooteboom (2 July 1934 – 20 April 2022) was a Dutch botanist, pteridologist, plant taxonomist, and journal editor. Biography Born in the Dutch East Indies, Hans Nooteboom with his family returned in 1939 to the Netherlands, where he remained during WWII. After graduation from secondary school in Rotterdam, he studied biology at Leiden University. There he studied under van Steenis and Robert Hegnauer and graduated with MSc.

Species Plantarum
' (Latin for "The Species of Plants") is a book by Carl Linnaeus, originally published in 1753, which lists every species of plant known at the time, classified into genus, genera. It is the first work to consistently apply binomial nomenclature, binomial names and was the starting point for the botanical nomenclature, naming of plants. Publication ' was published on 1 May 1753 by Laurentius Salvius in Stockholm, in two volumes. A second edition was published in 1762–1763, and a third edition in 1764, although this "scarcely differed" from the second. Further editions were published after Linnaeus' death in 1778, under the direction of Karl Ludwig Willdenow, the director of the Berlin-Dahlem Botanical Garden and Botanical Museum, Berlin Botanical Garden; the fifth edition was titled "fourth edition" and was published by Willdenow in four volumes, 1798 (1), 1800 (2), 1801 (31), 1803 (32), 1804 (33), 1805 (41), 1806 (42), rather than the dates printed on the volumes themselves. ...
