List Of Systems Of Plant Taxonomy
This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification. A wiktionary:taxonomic system, taxonomic system is a coherent whole of taxonomy (biology), taxonomic judgments on circumscription (taxonomy), 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 mileston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dicotyledones
The dicotyledons, also known as dicots (or, more rarely, dicotyls), are one of the two groups into which all the flowering plants (angiosperms) were formerly divided. The name refers to one of the typical characteristics of the group: namely, that the seed has two embryonic leaves or cotyledons. There are around 200,000 species within this group. The other group of flowering plants were called monocotyledons (or monocots), typically each having one cotyledon. Historically, these two groups formed the two divisions of the flowering plants. Largely from the 1990s onwards, molecular phylogenetic research confirmed what had already been suspected: that dicotyledons are not a group made up of all the descendants of a common ancestor (i.e., they are not a monophyletic In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the gr ...

Juglandales
Juglandales is an order of flowering plants. This order was recognised in several systems (e.g. Engler system and Wettstein system). The Cronquist system placed the order in the subclass Hamamelidae, as comprising the families Juglandaceae and Rhoipteleaceae, the latter consisting of only a single species. In the APG II system these two families are united into family Juglandaceae (with the split into two families being optional), and the family is placed in the order Fagales The Fagales are an order of flowering plants in the rosid group of dicotyledons, including some of the best-known trees.

Leitneriales
''Leitneria floridana'' (corkwood), the sole species in the genus ''Leitneria'', is a deciduous plant sexuality, dioecious shrub or small tree, found only in the southern United States states of Arkansas, Florida, Georgia (U.S. state), Georgia, Missouri and Texas. It grows at damp habitat (ecology), habitats, mostly in coastal areas and has extremely light wood with a density less than that of cork (material), cork. It typically reaches 2–4 m tall, occasionally up to 8 m. The trunk can reach 10 cm in diameter. The leaf, leaves are alternate, simple lanceolate, 5–20 cm long and 3–6 cm broad. In the past, it was treated as the only species in the family Leitneriaceae of the order Leitneriales, but Genetics, genetic research by the Angiosperm Phylogeny Group has recently resulted in its being transferred to the family Simaroubaceae in the Sapindales. It is named after the German natural scientist Edward Frederick Leitner, E. F. Leitner. Fossil record A single, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myricaceae
Myricaceae is a small family of dicotyledonous shrubs and small trees in the order Fagales with its type genus ''Myrica'', the sweet gales. There are three genera in the family, although some botanists separate many species from Myrica into a fourth genus ''Morella''. About 55 species are usually accepted in ''Myrica'' (with ''Morella'' included), one in '' Canacomyrica'', and one in '' Comptonia''. Well-known members of this family include bayberry and sweetfern. * '' Canacomyrica'' Guillaumin 1940 * '' Comptonia'' L'Hér. ex Aiton 1789 * ''Myrica'' L. 1753 (includes: '' Morella'' Lour. 1790) Systematics Modern molecular phylogenetics Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships.

Myricales
The Fagales are an order of flowering plants in the rosid group of dicotyledons, including some of the best-known trees. Well-known members of Fagales include: beeches, chestnuts, oaks, walnut, pecan, hickory, birches, alders, hazels, hornbeams, she-oaks, and southern beeches. The order name is derived from genus ''Fagus'' (beeches). Systematics Fagales include the following seven families, according to the APG III system of classification: *Betulaceae – birch family (''Alnus'', ''Betula'', ''Carpinus'', '' Corylus'', ''Ostrya'', and ''Ostryopsis'') *Casuarinaceae – she-oak family (''Allocasuarina'', ''Casuarina'', ''Ceuthostoma'', and ''Gymnostoma'') *Fagaceae – beech family ('' Castanea'', ''Castanopsis'', ''Chrysolepis'', ''Fagus'', ''Lithocarpus'', ''Notholithocarpus'', ''Quercus'', and '' Trigonobalanus'') *Juglandaceae – walnut family (''Alfaroa'', ''Carya'', '' Cyclocarya'', '' Engelhardia'', ''Juglans'', '' Oreomunnea'', '' Platycarya'', ''Pterocarya'', and '' ...

Fagaceae
The Fagaceae (; ) are a family of flowering plants that includes beeches, chestnuts and oaks, and comprises eight genera with around 1,000 or more species. Fagaceae in temperate regions are mostly deciduous, whereas in the tropics, many species occur as evergreen trees and shrubs. They are characterized by alternate simple leaves with pinnate venation, unisexual flowers in the form of catkins, and fruit in the form of cup-like (Calybium and cupule, cupule) nuts. Their leaves are often lobed, and both petiole (botany), petioles and stipules are generally present. Their fruits lack endosperm and lie in a scaly or spiny husk that may or may not enclose the entire nut, which may consist of one to seven seeds. In the oaks, genus ''Quercus'', the fruit is a non-valved nut (usually containing one seed) called an acorn. The husk of the acorn in most oaks only forms a cup in which the nut sits. Other members of the family have fully enclosed nuts. Fagaceae is one of the most ecologically i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betulaceae
Betulaceae, the birch family, includes six genera of deciduous nut-bearing trees and shrubs, including the birches, alders, hazels, hornbeams, hazel-hornbeam, and hop-hornbeams, numbering a total of 167 species. They are mostly natives of the temperate Northern Hemisphere, with a few species reaching the Southern Hemisphere in the Andes in South America. Their typical flowers are catkins and often appear before leaves. In the past, the family was often divided into two families, Betulaceae (''Alnus'', ''Betula'') and Corylaceae (the rest). Recent treatments, including the Angiosperm Phylogeny Group, have described these two groups as subfamilies within an expanded Betulaceae: Betuloideae and Coryloideae. Betulaceae flowers are monoecious, meaning that they have both male and female flowers on the same tree. Their flowers present as catkins and are small and inconspicuous, often with reduced perianth parts. These flowers have large feathery stamen and produce a high vo ...

Casuarinaceae
The Casuarinaceae are a family of dicotyledonous flowering plants placed in the order Fagales, consisting of four genera and 91 species of trees and shrubs native to eastern Africa, Australia, Southeast Asia, Malesia, Papuasia, and the Pacific Islands. At one time, all species were placed in the genus '' Casuarina''. Lawrence Alexander Sidney Johnson separated out many of those species and renamed them into the new genera of '' Gymnostoma'' in 1980 and 1982, '' Allocasuarina'' in 1982, and ''Ceuthostoma'' in 1988, with some additional formal descriptions of new species in each other genus. At the time, it was somewhat controversial. The monophyly of these genera was later supported in a 2003 phylogenetic study of the family. In the Wettstein system, this family was the only one placed in the order Verticillatae. Likewise, in the Engler, Cronquist, and Kubitzki systems, the Casuarinaceae were the only family placed in the order Casuarinales. Members of this family are charac ...
