Alexandre Henri Gabriel De Cassini
Viscount Alexandre Henri Gabriel (vicomte) de Cassini (9 May 1781 – 23 April 1832) was a French botanist and naturalist, who specialised in the sunflower family (Asteraceae) (then known as family Compositae). He was the youngest of five children of Jacques Dominique, Comte de Cassini, famous for completing the map of France, who had succeeded his father as the director of the Paris Observatory. He was also the great-great-grandson of famous Italian-French astronomer, Giovanni Domenico Cassini, discoverer of Jupiter's Great Red Spot and the Cassini division in Saturn's rings. The genus ''Cassinia'' was named in his honour by the botanist Robert Brown. He named many flowering plants and new genera in the sunflower family (Asteraceae), many of them from North America. He published 65 papers and 11 reviews in the '' ouveauBulletin des Sciences'' of the Société Philomatique de Paris between 1812 and 1821. In 1825, Cassini placed the North American taxa of ''Prenanthes'' (fami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ambroise Tardieu
Ambroise Tardieu (2 March 1788, in Paris – 17 January 1841, in Paris) was a France, French cartography, cartographer and engraving, engraver, and is celebrated for his version of John Arrowsmith (cartographer), John Arrowsmith's 1806 map of the United States. About Tardieu's son, Auguste Ambroise Tardieu (1818–1879), was also an artist and a famous forensic medical scholar, who supplied the illustrations for Pierre François Olive Rayer's three-volume ''Traité des maladies des reins'' (1839–41), a treatise on diseases of the kidneys. Neither should be confused with Jean Baptiste Pierre Tardieu, an unrelated French cartographer and engraver active in the early 19th century. Tardieu came from a family boasting a number of fine engravers, and was trained from an early age by his uncle, Pierre Alexandre Tardieu (1756–1844), a leading French engraver. Showing considerable talent in this field, Ambroise persevered and became a celebrated engraver of portraits. In addition ...

Cassini Division
Saturn has the most extensive and complex ring system of any planet in the Solar System. The rings consist of particles in orbit around the planet made almost entirely of water ice, with a trace component of rocky material. Particles range from micrometers to meters in size. There is no consensus as to what mechanism facilitated their formation: while investigations using theoretical models suggested they formed early in the Solar System's existence, newer data from '' Cassini'' suggests a more recent date of formation. In September 2023, astronomers reported studies suggesting that the rings of Saturn may have resulted from the collision of two moons "a few hundred million years ago". Though light reflected from the rings increases Saturn's apparent brightness, they are not themselves visible from Earth with the naked eye. In 1610, the year after Galileo Galilei's first observations with a telescope, he became the first person to observe Saturn's rings, though he could not se ...

19th-century French Botanists
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and confirm ce ...

Nabalus
''Nabalus'' is a genus of Asian and North American flowering plants in the tribe Cichorieae within the family Asteraceae. ''Nabalus'' is now considered the correct name for a group of plants in North America that were formerly considered to be members of '' Prenanthes'', and were included in that genus in the Flora of North America treatment. Common names for the genus include "rattlesnake root" and "white lettuce." The latter reflects its close relationship to lettuce (''Lactuca sativa'') but having flowers that are whitish or purplish-white in some species. Many (perhaps all) of the species are monocarpic perennials, in which an individual plant may live for multiple years in a vegetative condition but then will die after flowering and fruiting. Species ''Nabalus'' species include: Asian ''Nabalus'' species * '' Nabalus acerifolius'' - Japan * '' Nabalus angustilobus'' - Sichuan * '' Nabalus faberi'' - Guizhou, Sichuan * '' Nabalus leptanthus'' - Sichuan * '' Nabalus n ...

Prenanthes
''Prenanthes'' is a genus of plant in the family Asteraceae, often referred to as rattlesnake root. Molecular analysis in 2009 revealed that the genus as traditionally envisioned was polyphyletic, meaning that it is a conglomeration of species not closely related to one another.Posch, M., et al. (2011)A new trisaccharide derivative from ''Prenanthes purpurea''.Journal of the Serbian Chemical Society 76(6), 841-45. The genus formerly included species now placed in '' Aetheorhiza'', '' Askellia'', ''Brickellia'', '' Chondrilla'', '' Crepidiastrum'', ''Crepis'', '' Emilia'', '' Erythroseris'', '' Faberia'', '' Hololeion'', ''Hypochaeris'', '' Ixeris'', ''Lactuca'', '' Lapsanastrum'', ''Launaea'', ''Lygodesmia'', ''Nabalus'', '' Notoseris'', '' Paraprenanthes'', '' Parasenecio'', '' Picrosia'', '' Sonchella'', '' Sonchus'', '' Soroseris'', ''Stephanomeria'', ''Trixis'', and ''Youngia''.

Philomatic Society
The Philomaths, or Philomath Society ( or ''Towarzystwo Filomatów'', or ''Filomatų draugija''; from the Greek φιλομαθεῖς "lovers of knowledge"), was a secret student organization that existed from 1817 to 1823 at the Imperial University of Vilnius. History The society was created on 1 October 1817 in Vilnius, Vilna Governorate, Russian Empire, which had acquired those territories in the Partitions of Poland in 1794. The society was composed of students and alumni of the Imperial University of Vilnius. Notable members included Józef Jeżowski (co-founder and president), Jan Czeczot (co-founder), Józef Kowalewski (co-founder), Onufry Pietraszkiewicz (co-founder), Tomasz Zan (co-founder), Adam Mickiewicz (co-founder), Antoni Edward Odyniec, Ignacy Domejko, Teodor Łoziński, Franciszek Malewski, , Aleksander Chodźko, Michał Kulesza.

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Brown (Scottish Botanist From Montrose)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose, Scotland on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a mi ...

Cassinia
''Cassinia'' is a genus of about fifty-two species of flowering plants in the family Asteraceae that are native to Australia and New Zealand. Plants in the genus ''Cassinia'' are shrubs, sometimes small trees with leaves arranged alternately, and heads of white, cream-coloured, yellow or pinkish flowers surrounded by several rows of bracts. Description Plants in the genus ''Cassinia'' are shrubs or small trees, sometimes with sticky foliage. The leaves are arranged alternately, the edges flat to strongly rolled under, and the flowers white to cream-coloured, yellow or pinkish, arranged in heads, the heads in cylindrical, top-shaped or bell-shaped corymbs. The heads are surrounded by several rows of usually erect, boat-shaped bracts. The florets are bisexual and cylindrical with five lobes and the cypselas are small and usually have a pappus of bristles. Taxonomy The genus ''Cassinia'' was first formally described in 1817 by Robert Brown in his book ''Observations on the Natu ...
