Élie Antoine Octave Lignier
Élie Antoine Octave Lignier (25 February 1855, in Pougy – 19 March 1916, in Caen) was a French botanist, known for his work in the field of paleobotany. From 1880 to 1887 he worked as assistant to Charles Eugène Bertrand at the University of Lille. He obtained his doctorate in sciences at Paris, and from 1887 gave lectures in botany at the University of Caen. In 1889 he received the title of professor, and from 1896 served as director of the botanical garden at Caen.BHL Taxonomic literature : a selective guide to botanical publications

Melastomataceae
Melastomataceae () is a family of dicotyledonous flowering plants found mostly in the tropics (two-thirds of the genera are from the New World tropics) comprising c. 175 genera and c. 5115 known species. Melastomes are annual or perennial herbs, shrubs, or small trees. Description The leaves of melastomes are somewhat distinctive, being opposite, decussate, and usually with 3-7 longitudinal veins arising either from the base of the blade, plinerved (inner veins diverging above base of blade), or pinnately nerved with three or more pairs of primary veins diverging from the mid-vein at successive points above the base. Flowers are perfect, and borne either singly or in terminal or axillary, paniculate cymes. Ecology A number of melastomes are regarded as invasive species once naturalized in tropical and subtropical environments outside their normal range. Examples are Koster's curse (''Clidemia hirta''), '' Pleroma semidecandrum'' and '' Miconia calvescens'', but many othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleobotanists
Paleobotany or palaeobotany, also known as paleophytology, is the branch of botany dealing with the recovery and identification of plant fossils from geological contexts, and their use for the biological reconstruction of past environments (paleogeography), and the evolutionary history of plants, with a bearing upon the evolution of life in general. It is a component of paleontology and paleobiology. The prefix ''palaeo-'' or ''paleo-'' means "ancient, old", and is derived from the Greek adjective , . Paleobotany includes the study of land plants, as well as the study of prehistoric marine photoautotrophs such as photosynthetic algae, seaweeds or kelp. A closely related field is palynology, which is the study of fossilized and extant spores and pollen. Paleobotany is important in the reconstruction of ancient ecological and climate systems, known as paleoecology and paleoclimatology respectively. It is fundamental to the study of green plant development and evolution. Paleobot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Academic Staff Of The University Of Caen Normandy
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of tertiary education. The name traces back to Plato's school of philosophy, founded approximately 386 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. The Royal Spanish Academy defines academy as scientific, literary or artistic society established with public authority and as a teaching establishment, public or private, of a professional, artistic, technical or simply practical nature. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Aube
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determinat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Calycanthaceae
The Calycanthaceae (sweetshrubs or spicebushes) are a small family of flowering plants in the order Laurales. The family contains three genera and only 10 known species , restricted to warm temperate and tropical regions: They are aromatic, deciduous shrubs growing to 2–4 m tall, except for ''Idiospermum'', which is a large evergreen tree. The flowers are white to red, with spirally arranged tepals. DNA-based phylogenies indicate the Northern Hemisphere ''Calycanthus'' and ''Chimonanthus'' diverged from each other in the mid-Miocene, while the Australian ''Idiospermum'' had already diverged by the Upper Cretaceous and likely represents a remnant of a former Gondwanan distribution of Calycanthaceae. The oldest definitive fossil of the family is '' Jerseyanthus'' from the Turonian of New Jersey; the even earlier '' Araripia'' from the Aptian of Brazil and '' Virginianthus'' from the Albian of Virginia may also represent members of the family, but may also be stem-Calycantha ...

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 ...
