Inflorecence scheme and floral diagram. 1 – glume, 2 – lemma, 3 – awn, 4 – palea, 5 – lodicules, 6 – stamens, 7 – ovary, 8 – styles. Flowers of Poaceae are characteristically arranged in spikelets, each having one or more florets. [8]: 12 The spikelets are further grouped into panicles or spikes. The part of the spikelet that ...
Poaceae, also known as the true grasses, is the fourth largest plant family in the world with around 12,000 species and roughly 800 genera. [ 1 ] [ 2 ] They contain, among others, the cereal crop species and other plants of economic importance, such as the bamboos , and several important weeds .
Within the order, by far the most important family economically is the family of grasses (Poaceae, syn. Gramineae), which includes the starch staples barley, maize, millet, rice, and wheat as well as bamboos (mostly used structurally, like wood, but somewhat as vegetables), and a few "seasonings" like sugarcane and lemongrass. Graminoids ...
The first classification was published in Russian in 1954, and came to the attention of the rest of the world after publication of an English translation in 1958 as Origin of Angiospermous Plants. Further versions appeared in 1959 ( Die Evolution der Angiospermen ) and 1966 ( Sistema i filogeniia tsvetkovykh rastenii ). [ 1 ]
The BOP clade (sometimes BEP clade) is one of two major lineages (or clades) of undefined taxonomic rank in the grasses , containing more than 5,400 species, about half of all grasses. Well-known members of this clade include rice , some major cereals such as wheat , barley , oat , and rye , many lawn and pasture grasses, and bamboos .

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 Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. [1] [2] [3]
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.
