List Of Systems Of Plant Taxonomy
This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification. A taxonomic system is a coherent whole of taxonomic judgments on circumscription and placement of the considered taxa. It is only a "system" if it is applied to a large group of such taxa (for example, all the flowering plants). There are two main criteria for this list. A system must be taxonomic, that is deal with many plants, by their botanical names. Secondly it must be a system, i.e. deal with the relationships of plants. Although thinking about relationships of plants had started much earlier (see history of plant systematics), such systems really only came into being in the 19th century, as a result of an ever-increasing influx from all over the world of newly discovered plant species. The 18th century saw some early systems, which are perhaps precursors rather than full taxonomic systems. A milestone event was the publication of ''Species Plantarum'' by Linnaeus which serve ...

Ulvaceae
Ulvaceae () is a widely distributed family of thin green algae having either a flat or a hollow tubular thallus, reproducing by the conjugation of planogametes or of zoospores, and being classed among the Ulotrichales or now more commonly placed in the order Ulvales. Genera in the family Ulvaceae * ''Enteromorpha'' * '' Enteronia'' * ''Gemina'' * '' Letterstedtia'' * ''Lobata'' * ''Ochlochaete'' * ''Percursaria'' * ''Phycoseris'' * ''Ruthnielsenia'' * '' Solenia'' * ''Ulva'' * '' Ulvaria'' * ''Umbraulva The genus ''Umbraulva'', which is a green alga within the Ulvaceae family, was proposed by Bae and Lee in 2001.

Chlorococcales
Chlorococcales is a formerly recognized Order (biology), order of green algae in the Class (biology), class Chlorophyceae. , the type family Chlorococcaceae was placed in the order Chlamydomonadales. Conventionally, many groups of coccoid green algae were lumped in the order Chlorococcales sensu lato by Komárek & Fott (1983), based on Pascher's (1918) idea of establishing orders according to life forms. However, coccoid green algae are currently placed in several orders of Chlorophyceae, Trebouxiophyceae, Ulvophyceae (e.g., ''Chlorocystis'') and Prasinophyceae within the division Chlorophyta, or in the division Charophyta (e.g., Chlorokybales, Desmidiales). Families According to Komárek & Fott (1983): * Chlorococcaceae (Chlorococcoideae, Spongiococcoideae) * Palmellaceae (Hormotiloideae, Palmelloideae, Neochloridoideae, Chlorosarcinoideae) * Chlorochytriaceae * Dicranochaetaceae * Characiaceae (Fernandinelloideae, Characioideae, Schroederioideae) * Treubariaceae * Golenki ...

Mesotaeniaceae
The Mesotaeniaceae are a small family of unicellular green algae known as the "saccoderm desmids". The Mesotaeniaceae appear to be sister or ancestral to the Zygnemataceae. The desmids are a deep branching group of Zygnemataceae. ''Spirotaenia'' was found to be a basal green alga. Genera The Mesotaeniaceae includes the following genera: * ''Ancylonema'' Berggren, 1872 * ''Cylindrocystis'' Meneghini ex De Bary, 1858 * '' Geniculus'' Prescott, 1967 * ''Mesotaenium'' Nägeli, 1849 * ''Netrium'' (Nägeli) Itzigsohn & Rothe, 1856 * '' Nucleotaenium'' Gontcharov & Melkonian, 2010 * '' Planotaenium'' (Ohtani) Petlovany & Palamar-Mordvintseva, 2009 * '' Roya'' West & G.S.West, 1896 * ''Spirotaenia'' Brébisson, 1848 * '' Tortitaenia'' A.J.Brook, 1998 Synonyms: * ''Endospira'' Brébisson, nom. inval., is a synonym of Spirotaenia * ''Entospira'' Kuntze, 1898 is a synonym of ''Spirotaenia'' * ''Polytaenia'' A.J.Brook, 1997, nom. illeg.

Zygnemataceae
The Zygnemataceae are a family of filamentous or unicellular, uniseriate (unbranched) green algae. The filaments are septated and reproduction is by conjugation; ''Spirogyra'' is commonly used in schools to demonstrate this kind of reproduction. The family is notable for its diversely shaped chloroplasts, such as stellate in ''Zygnema'', helical in ''Spirogyra'', and flat in ''Mougeotia''. The Zygnemataceae are cosmopolitan, but though all generally occur in the same types of habitats, ''Mougeotia'', ''Spirogyra'', and ''Zygnema'' are by far the most common; in one study across North America, 95% of the Zygnemataceae collected were in these three genera. Classification and identification is primarily by the morphology of the conjugation, which is somewhat rare to find in natural populations of permanent water bodies; when in the vegetative state, the rarer genera resemble the three most common, and are often mistaken for them and catalogued as such. Conjugation can be induced in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zygnematales
The Zygnematales ( el, ζυγός (''zygós'') and νῆμα (''nḗma'') ( nom.), νήματος (''nḗmatos'') (gen.)), also called the Conjugatales, are an order of green algae, comprising several thousand different species in two families. The larger family Zygnemataceae, with well-known genera such as ''Zygnema'' and ''Spirogyra'', includes members that grow as unbranched filaments, which grow longer through normal cell division. This group includes the desmids. Most members of both families live in freshwater, and form an important component of the algal scum that grows on or near plants, rocks, and various debris. Systematically they fall within the division Charophyta/Streptophyta, in which the land plants (Embryophyta) emerged. Sexual reproduction in Zygnematales takes place through a process called ''conjugation''. Here filaments of opposite gender line up, and tubes form between corresponding cells. The male cells then become amoeboid and crawl across, or sometimes b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oedogoniaceae
The Oedogoniales are an order of filamentous freshwater green algae of the class Chlorophyceae. The order is well-defined and has several unique features, including asexual reproduction with zoospores that possess stephanokont flagella: numerous short flagella arranged in a subapical whorl. The oedogoniales have a highly specialized type of oogamy, and an elaborate method of cell division which results in the accumulation of apical caps. The order comprises one family, Oedogoniaceae, with three genera. Some common features among these genera may be obscure. The hairs of ''Bulbochaete'' and the heterotrichous system ''Oedocladium'' are similar to Chaetophorales, with which they may share a distant relationship. Of the genus Oedogonium' there are over 330 species, about 70 species of ''Bulbochaete'', and 10 species of ''Oedocladium''. More than half of these species are known to North America.Tiffany, L. H. (1955). ''Geographic Distribution of the North American Species of the Oed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
