Centrolepidaceae
Centrolepidaceae are a family of flowering plants now included in Restionaceae following APG IV (2016). The botanical name has been recognized by most taxonomists. The APG II system, of 2003 (unchanged from the APG system, 1998), also recognised such a family, and assigned it to the order Poales in the clade commelinids in the monocots. The family was regarded as containing three genera, '' Aphelia'', ''Centrolepis'', and ''Gaimardia'', with about 35 species total, found in Australia, New Zealand, southern South America and Southeast Asia Southeast Asia, also spelled South East Asia and South-East Asia, and also known as Southeastern Asia, South-eastern Asia or SEA, is the geographical United Nations geoscheme for Asia#South-eastern Asia, south-eastern region of Asia, consistin ....

Poales Families
The Poales are a large order of flowering plants in the monocotyledons, and includes families of plants such as the grasses, bromeliads, and sedges. Sixteen plant families are currently recognized by botanists to be part of Poales. Description The flowers are typically small, enclosed by bracts, and arranged in inflorescences (except in three species of the genus ''Mayaca'', which possess very reduced, one-flowered inflorescences). The flowers of many species are wind pollinated; the seeds usually contain starch. Taxonomy The APG III system (2009) accepts the order within a monocot clade called commelinids, and accepts the following 16 families: The earlier APG system (1998) adopted the same placement of the order, although it used the spelling "commelinoids". It did not include the Bromeliaceae and Mayaceae, but had the additional families Prioniaceae (now included in Thurniaceae), Sparganiaceae (now in Typhaceae), and Hydatellaceae (now transferred out of the monocots; ...

APG System
The APG system (Angiosperm Phylogeny Group system) of plant classification is the first version of a modern, mostly molecular-based, system of plant taxonomy. Published in 1998 by the Angiosperm Phylogeny Group, it was replaced by the improved APG II in 2003, APG III system in 2009 and APG IV system in 2016. History The original APG system is unusual in being based, not on total evidence, but on the cladistic analysis of the DNA sequences of three genes, two chloroplast genes and one gene coding for ribosomes. Although based on molecular evidence only, its constituent groups prove to be supported by other evidence as well, for example pollen morphology supports the split between the eudicots and the rest of the former dicotyledons. The system is rather controversial in its decisions at the family level, splitting a number of long-established families and submerging some other families. It also is unusual in not using botanical names above the level of order, that is, an orde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Restionaceae
The Restionaceae, also called restiads and restios, are a family (biology), family of flowering plants native to the Southern Hemisphere; they vary from a few centimeters to 3 meters in height. Following the APG IV system, APG IV (2016): the family now includes the former families Anarthriaceae, Centrolepidaceae and Lyginiaceae, and as such includes 51 genera with 572 known species. Based on evidence from fossil pollens, the Restionaceae likely originated more than 65 million years ago during the Cretaceous, Late Cretaceous period, when the southern continents were still part of Gondwana.Bremer, K. (2002). "Gondwanan Evolution of the Grass Alliance of Families (Poales)." ''Evolution'', 56(7): 1374-1387 Description The family consists of tufted or rhizomatous, herbaceous plants belonging to a group of monocotyledons that includes several similar families, such as the Cyperaceae, sedges, Juncaceae, rushes, and Poaceae, grasses.

APG IV System
The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG). It was published in 2016, seven years after its predecessor the APG III system was published in 2009, and 18 years after the first APG system was published in 1998. In 2009, a linear arrangement of the system was published separately; the APG IV paper includes such an arrangement, cross-referenced to the 2009 one. Compared to the APG III system, the APG IV system recognizes five new orders (Boraginales, Dilleniales, Icacinales, Metteniusales and Vahliales), along with some new families, making a total of 64 angiosperm orders and 416 families. In general, the authors describe their philosophy as "conservative", based on making changes from APG III only where "a well-supported need" has been demonstrated. This has sometimes resulted in placements that a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commelinids
In plant taxonomy, commelinids (originally commelinoids) (plural, not capitalised) is a clade of flowering plants within the monocots, distinguished by having cell walls containing ferulic acid. The commelinids are the only clade that the APG IV system has informally named within the monocots. The remaining monocots are a paraphyletic unit. Also known as the commelinid monocots it forms one of three groupings within the monocots, and the final branch; the other two groups are the alismatid monocots and the lilioid monocots. Description Members of the commelinid clade have cell walls containing UV-fluorescent ferulic acid. Taxonomy The commelinids were first recognized as a formal group in 1967 by Armen Takhtajan, who named them the Commelinidae and assigned them to a subclass of Liliopsida (monocots). The name was also used in the 1981 Cronquist system. However, by the release of his 1980 system of classification, Takhtajan had merged this subclass into a larger one, and no ...
