The graminid clade is a clade of plants in the order Poales uniting four families, of which the grasses (Poaceae) are the most species-rich. Its sister group is the restiid clade. [1]

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.
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 pollens, the Restionaceae likely originated more than 65 million years ago during the Late Cretaceous period, when the southern continents were still part of Gondwana.
The Typhaceae are a family of flowering plants, sometimes called the cattail family. The botanical name for the family has been recognized by most taxonomists.
The Xyridaceae are a family of flowering plants. This family has been recognized by many taxonomists and is known as the yellow-eyed grass family.
In biological taxonomy the type genus is the genus which defines a biological family and the root of the family name.
Sparganiaceae is a family of flowering plants. Such a family was previously recognized by most taxonomists.
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 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.
The APG II system of plant classification is the second, now obsolete, version of a modern, mostly molecular-based, system of plant taxonomy that was published in April 2003 by the Angiosperm Phylogeny Group. It was a revision of the first APG system, published in 1998, and was superseded in 2009 by a further revision, the APG III system.
In plant taxonomy, commelinids is a clade of flowering plants within the monocots, distinguished by having cell walls containing ferulic acid.
The Rapateaceae are a family of flowering plants. The botanical name has been recognized by most taxonomists.
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. The three genera are herbaceous but differ greatly in characteristics.
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 Ecdeiocoleaceae comprise a family of flowering plants with two genera and three species. The botanical name has rarely been recognized by taxonomists.
Flagellaria is the sole genus in the flowering plant family Flagellariaceae with only five species. The family has historically been recognized by few taxonomists. The APG II system, of 2003, does recognize such a family, and assigns it to the order Poales in the clade commelinids, in the monocots.
The Joinvilleaceae are a family of flowering plants with a single genus including four species. The APG II system, of 2003 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.
Xyris is a genus of flowering plants, the yelloweyed grasses, in the yellow-eyed-grass family. The genus counts over 250 species, widespread over much of the world, with the center of distribution in the Guianas.
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.
Poale Zion was a movement of Marxist–Zionist Jewish workers founded in various cities of Poland, Europe and the Russian Empire in about the turn of the 20th century after the Bund rejected Zionism in 1901.
Dov Ber Borochov was a Marxist Zionist and one of the founders of the Labor Zionist movement. He was also a pioneer in the study of the Yiddish language.
