Poales is an order of flowering plants in the monocotyledons, and includes families of plants such as the grasses, bromeliads, and sedges. Plants are living Organisms belonging to the kingdom Plantae. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Liliopsida is a Botanical name for the class containing the family Liliaceae (or Lily Family John Kunkel Small (January 31 1869- January 20 1938 was an American Botanist. This article is about the taxonomic rank for the sequence of species in a taxonomic list see Taxonomic order In scientific classification used The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Monocotyledons or monocots are one of two major groups of Flowering plants (angiosperms that are traditionally recognised the other being Dicotyledons Poaceae or Gramineae is a family in the Class Liliopsida of the flowering plants. The family Cyperaceae, or the sedges, is a taxon of monocot Flowering plants that superficially resemble grasses or rushes

Recent studies (Bremer, 2000) place the origin of the Poales in South America nearly 115 million years ago. South America is a Continent of the Americas, situated entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a The earliest known fossils include pollen and fruits that have been dated to the late Cretaceous. Pollen is a fine to coarse powder consisting of microgametophytes ( pollen grains) which produce the male Gametes (sperm cells of The Cretaceous (kriːˈteɪʃəs, usually abbreviated 'K' for its German translation "Kreide" is a geologic period and system, reaching from the end of The flowers are typically small, enclosed by bracts, and arranged in an inflorescence (except in the genus Mayaca, with solitary terminal flowers). A flower, also known as a bloom or Blossom, is the reproductive structure found in Flowering plants (plants of the division Magnoliophyta, also An inflorescence is a group or cluster of Flowers arranged on a stem that is composed of a main Branch or a complicated arrangement of branches Mayaca is a Genus of Flowering plants often placed in its own family, the Mayacaceae. The flowers of many species are wind pollinated; the seeds usually contain starch. Starch, CAS # 9005-25-8 Chemical formula (C6H10O5n is a Polysaccharide

The APG II system (2003) accepts the order and places it in clade commelinids, in the monocots. In Plant taxonomy, the name commelinids (plural not capitalised is used by the APG II system for a Clade within the Monocots, which in its Monocotyledons or monocots are one of two major groups of Flowering plants (angiosperms that are traditionally recognised the other being Dicotyledons It uses this circumscription:

The APG system (1998) adopted the same placement, although it used the spelling "commelinoids", and used the following circumscription (i.

The Cronquist system did not include an order named Poales, assigning these families to the orders Bromeliales, Cyperales, Hydatellales, Juncales, Restionales and Typhales.

Restionales is a Botanical name for an order of Flowering plants. Typhales is a Botanical name for an order of Flowering plants In the Cronquist system the name was used for an order placed in the

In early systems an order including the grass family did not go by the name Poales but by a descriptive botanical name such as Graminales in the Engler system (update of 1964) and in the Hutchinson system (first edition, first volume, 1926), Glumiflorae in the Wettstein system (last revised 1935) or Glumaceae in the Bentham & Hooker system (third volume, 1883). This list of systems of plant taxonomy presents “taxonomic systems” used in plant classification Descriptive botanical names: Article 16 of the ICBN rules that a name above the rank of family may be either descriptive or formed from the name One of the prime systems of plant taxonomy, the Engler system was devised by Adolf Engler.

By far the most important family economically is the family of grasses (Poaceae, syn. Poaceae or Gramineae is a family in the Class Liliopsida of the flowering plants. Gramineae), which includes barley, maize, millet, rice, and wheat.
