Gomontia Arhiza
''Gomontia'' is a genus of green algae, in the family Gomontiaceae. The genus name of ''Gomontia'' is in honour of Maurice-Augustin Gomont (1839 - 1909), who was a French phycologist. The genus was circumscribed by Jean-Baptiste Édouard Bornet and Charles Henri Marie Flahault Charles Henri Marie Flahault (3 October 1852 – 3 February 1935) was a French botanist, among the early pioneers of phytogeography, phytosociology, and forest ecology.

Jean-Baptiste Édouard Bornet
Jean-Baptiste Édouard Bornet (September 2, 1828, Guérigny – December 18, 1911, Paris) was a French botanist. Life Bornet studied medicine in Paris, and in 1886 became a member of the French Académie des sciences. With Gustave Thuret, he was co-author of ''Notes algologiques'' (1876-1880) and the ''Études phycologiques'' (1878), both works being published after Thuret's death in 1875. He helped establish the nature of lichens and was the first to find the reproductive process of red algae. In the field of lichenology, he wrote ''Recherches sur les gonidies des lichens'' (1873). With Charles Flahault, he published on Nostocaceae: ''Revision des Nostocacées héterocystées'' (1886–88). Awards and honours In 1877, botanist Munier-Chalmas published '' Bornetella'' is a genus of green algae in the family Dasycladaceae and named in Jean-Baptiste Édouard Bornet's honor. Bornet was elected a member of the Royal Swedish Academy of Sciences in 1888. He was awarded the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Ulvophyceae Genera
The Ulvophyceae or ulvophytes are a class of green algae, distinguished mainly on the basis of ultrastructural morphology, life cycle and molecular phylogenetic data.Graham LE, Graham JM, Wilcox LW (2009) ''Algae''. 2nd Edition. Benjamin Cummings (Pearson), San Francisco, CA The sea lettuce, ''Ulva'', belongs here. Other well-known members include ''Caulerpa'', ''Codium'', ''Acetabularia'', ''Cladophora'', '' Trentepohlia'' and ''Monostroma''. The Ulvophytes are diverse in their morphology and their habitat. Most are seaweeds such as those listed above. Others, such as ''Rhizoclonium'', ''Pithophora'' and some species of ''Cladophora'' live in fresh water and in some areas are considered weeds. Evolution The origin and early diversification of the Ulvophyceae likely took place in the late Neoproterozoic. Although most contemporary ulvophytes are marine macroalgae (seaweeds), ancestral ulvophytes may have been freshwater, unicellular green algae. Molecular phylogenetic eviden ...

Charles Henri Marie Flahault
Charles Henri Marie Flahault (3 October 1852 – 3 February 1935) was a French botanist, among the early pioneers of phytogeography, phytosociology, and forest ecology. The word '' relevé'' for a plant community sample is his invention. Early life and education Flahault was born in Bailleul, Nord, and received his Baccalauréat de Lettres at Douai in 1872, after which he became a gardener at the Jardin des Plantes de Paris. He was noticed by Joseph Decaisne (1807–1882), who gave him private lessons, after which he entered the Sorbonne in 1874 to study in the laboratory of Philippe Van Tieghem (1839–1914), obtaining his doctoral degree in biology in 1878. He continued his studies at Uppsala University in 1879 together with Gaston Bonnier. Career In 1881 joined the University of Montpellier where in 1883 he became professor of botany, and in 1890 he founded the ''Institut de Botanique''.

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Green Algae
The green algae (singular: green alga) are a group consisting of the Prasinodermophyta and its unnamed sister which contains the Chlorophyta and Charophyta/Streptophyta. The land plants (Embryophytes) have emerged deep in the Charophyte alga as sister of the Zygnematophyceae. Since the realization that the Embryophytes emerged within the green algae, some authors are starting to properly include them. The completed clade that includes both green algae and embryophytes is monophyletic and is referred to as the clade Viridiplantae and as the kingdom Plantae. The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic, multicellular seaweeds. There are about 22,000 species of green algae. Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds. A few other organi ...
