Poales
The Poales are a large order (biology), order of flowering plants in the monocotyledons, and includes families of plants such as the Poaceae, grasses, bromeliads, Juncaceae, rushes and Cyperaceae, sedges. 14 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 IV system (2016) accepts the order within a monocot clade called commelinids, with 14 families.Huijun Wang, Zhigang Wu, Tao Li, Jindong Zhao, Phylogenomics resolves the backbone of Poales and identifies signals of hybridization and polyploidy, ''Molecular Phylogenetics and Evolution'', Volume 200, 2024, 108184, ISSN 1055-7903, https://doi.org/10.1016/j.ympev.2024.108184.

Monocot
Monocotyledons (), commonly referred to as monocots, (Lilianae ''sensu'' Chase & Reveal) are flowering plants whose seeds contain only one Embryo#Plant embryos, embryonic leaf, or cotyledon. A monocot taxon has been in use for several decades, but with various ranks and under several different names. The APG IV system recognises its monophyly but does not assign it to a taxonomic rank, and instead uses the term "monocots" to refer to the group. Monocotyledons are contrasted with the Dicotyledon, dicotyledons, which have two cotyledons. Unlike the monocots however, the dicots are not Monophyly, monophyletic and the two cotyledons are instead the ancestral characteristic of all flowering plants. Botanists now classify dicots into the eudicots ("true dicots") and several Basal (phylogenetics), basal lineages from which the monocots emerged. The monocots are extremely important economically, culturally, and ecologically, and make up a majority of plant biomass used in agriculture. Com ...

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 to Southwest Australia Southwest Australia is a biogeographic region in Western Australia. It includes the Mediterranean-climate area of southwestern Australia, which is home to a diverse and distinctive flora and fauna. The region is also known as the Southwest Au ..., have been described to date. References External linksEcdeiocoleaceaein L. Watson and M.J. Dallwitz (1992 onwards).

Commelinids
In plant taxonomy, commelinids (originally commelinoids) is a clade of flowering plants within the monocots, distinguished by having cell walls containing ferulic acid. Well-known commelinids include palms and relatives (order Arecales), dayflowers, spiderworts, kangaroo paws, and water hyacinth (order Commelinales), grasses, bromeliads, rushes, and sedges (order Poales), ginger, cardamom, turmeric, galangal, bananas, plantains, and bird of paradise flower (order Zingiberales). 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 and Phylogeny The commelinids constitute a well-su ...

Restionaceae
The Restionaceae, also called restiads and restios, are a family of flowering plants native to the Southern Hemisphere; they vary from a few centimeters to 3 meters in height. Following the 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 pollen, the Restionaceae likely originated more than 65 million years ago during the 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 sedges, rushes, and grasses. They have green, photosynthetic stems and leaves that have been reduced to sheaths. Their flowers are extremely small and in sp ...

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 tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Mayacaceae
''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 * ...

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.

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 fol ...
