Poales
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; ...

Monocotyledon
Monocotyledons (), commonly referred to as monocots, (Lilianae ''sensu'' Chase & Reveal) are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf, or cotyledon. They constitute one of the major groups into which the flowering plants have traditionally been divided; the rest of the flowering plants have two cotyledons and are classified as dicotyledons, or dicots. Monocotyledons have almost always been recognized as a group, but with various taxonomic ranks and under several different names. The APG III system of 2009 recognises a clade called "monocots" but does not assign it to a taxonomic rank. The monocotyledons include about 60,000 species, about a quarter of all angiosperms. The largest family in this group (and in the flowering plants as a whole) by number of species are the orchids (family Orchidaceae), with more than 20,000 species. About half as many species belong to the true grasses ( Poaceae), which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ecdeiocoleaceae
The Ecdeiocoleaceae comprise a family of flowering plants with two genera and three species. The botanical name has rarely been recognized by taxonomists. The APG II system, in 2003 (unchanged from the APG system, 1998), does recognize such a family, and assigns it to the order Poales in the clade commelinids, in the monocots. Three species in two genera, '' Ecdeiocolea'' and '' Georgeantha'', both endemic Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found else ... to Southwest Australia, have been described to date.

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, an ...

Anarthriaceae
The Anarthriaceae are a family of three genera, '' Anarthria'', '' Hopkinsia'' and '' Lyginia'' of flowering plants, now included in Restionaceae following APG IV (2016). The family is accepted in the Angiosperm Phylogeny Group's classification system, APG III system, but is not considered a separate family in many other taxonomic systems.Watson, L., and Dallwitz, M.J. 1992 onwards. The families of flowering plants: descriptions, illustrations, identification, and information retrieval. Version: 19 December 2012. http://delta-intkey.com The three genera are herbaceous but differ greatly in characteristics. The APG II system, of 2003 (unchanged from the APG system, of 1998), does recognize this family, and assigns it to the order Poales in the clade commelinids, in the monocots. The family contains three genera and 10 species, and is found in Southwest Australia Southwest Australia is a biogeographic region in Western Australia.

Mayaca
''Mayaca'' is a genus of flowering plants, often placed in its own family, the Mayacaceae (or Mayaceae in earlier systems). In the APG II system of 2003, it is assigned to the order Poales in the clade commelinids. The Cronquist system, of 1981, also recognised such a family and placed it in the order Commelinales in the subclass Commelinidae. The group is widely distributed in Latin America from Mexico to Argentina, as well as in the West Indies, the southeastern United States, and central Africa. Species Eighteen or so species names have been proposed, but only 5 are accepted as distinct. * ''Mayaca baumii'' Gürke - Congo-Brazzabille, Zaïre, Angola, Zambia * ''Mayaca fluviatilis'' Aubl. - southeastern United States from Texas to North Carolina; West Indies (Cuba, Jamaica, Trinidad); Latin America from central Mexico to Argentina * ''Mayaca kunthii'' Seub. - Venezuela, Brazil, Uruguay * ''Mayaca longipes'' Mart. ex Seub. - Venezuela, Brazil, Colombia, the Guianas * ''Ma ...

Bromeliaceae
The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, '' Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss ('' Tillandsia usneoides''), and terrestrial species, such as the pineapple ('' Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte '' Tillandsia'' species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thurniaceae
The Thurniaceae are a family of flowering plants composed of two genera with four species. The botanical name has been recognized by most taxonomists. The APG II system, of 2003, also recognizes such a family, and assigns it to the order Poales in the clade commelinids, in the monocots. The family consists of two genera, totalling only a few species, perennial plants of wet habitats in South America and South Africa. This represents a slight change from the APG system, 1998, which treated the two genera as each constituting their own family ( Prioniaceae and Thurniaceae), both placed in the order Poales. The Cronquist system of 1981 also recognized such a family and placed it in the order Juncales in the subclass Commelinidae in class Liliopsida in division Magnoliophyta.

Joinvilleaceae
The Joinvilleaceae are a family of flowering plants with a single genus including four species. The APG II system, of 2003 (unchanged from the APG system, 1998) assigns it to the order Poales in the clade commelinids in the monocots. The family consists of one genus with four currently accepted species, distributed from the Malay Peninsula to the Caroline Islands and high islands in the Pacific Ocean. It is evolutionarily significant as a relictual group closely related to grasses. They closely resemble large grass plants, in both general appearance and microanatomy, but possess fleshy fruits.

APG III System
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families follo ...
