'' Beckmannia eruciformis'' is a Eurasian perennial, and '' Beckmannia syzigachne'' is an annual grass found in North America and Asia. The genus was named for the German scientist Johann Beckmann.

List Of Poaceae Genera
The true grasses ( Poaceae) are one of the largest plant families, with around 12,000 species and roughly 800 genera. They contain, among others, the cereal crop species and other plants of economic importance, such as the bamboos, and several important weeds. Grasses probably originated in the understory of tropical rainforests in the Late Cretaceous, but have since come to occupy a wide range of different habitats. Notably, they are the dominant species in grasslands, open habitats that cover around one fifth of the earth's terrestrial surface. The C4 photosynthetic pathway has evolved at least 22 times independently in the grasses; C4 species are more competitive than C3 plants in open habitats with high light intensity and warm temperatures. The deeper relationships in the family have been resolved by recent molecular phylogenetic work. This has been translated into a modern classification which divides the grasses into twelve subfamilies and a number of tribes, with ...

Brachiopod
Brachiopods (), phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection. Two major categories are traditionally recognized, articulate and inarticulate brachiopods. The word "articulate" is used to describe the tooth-and-groove structures of the valve-hinge which is present in the articulate group, and absent from the inarticulate group. This is the leading diagnostic skeletal feature, by which the two main groups can be readily distinguished as fossils. Articulate brachiopods have toothed hinges and simple, vertically-oriented opening and closing muscles. Conversely, inarticulate brachiopods have weak, untoothed hinges and a more complex system of vertical and oblique (diagonal) muscles used to keep the two valves aligned. In many brachiopods, a ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Nicolaus Thomas Host
Nicolaus Thomas Host (December 6, 1761 in Fiume, now Rijeka – January 13, 1834 in Schönbrunn) was a Croatian botanist and the personal physician of Holy Roman Emperor Francis II. His botanical works include ''Synopsis plantarum in Austria'' and the four-volume ''Austriacorum Icones et descriptions graminum''; he was also the first director of the botanical garden at the Belvedere palace. The genus ''Hosta ''Hosta'' (, syn. ''Funkia'') is a genus of plants commonly known as hostas, plantain lilies and occasionally by the Japanese name gibōshi. Hostas are widely cultivated as shade-tolerant foliage plants.

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Johann Beckmann
Johann Beckmann (1739–1811) was a German scientific author and coiner of the word technology, to mean the science of trades. He was the first man to teach technology and write about it as an academic subject. Life He was born on 4 June 1739 at Hoya in Hanover, where his father was postmaster and receiver of taxes. He was educated at Stade and the university of Göttingen, where he studied theology, mathematics, physics, natural history, and public finance and administration. After completing his studies, in 1762 he made a study tour through Brunswick and the Dutch Republic examining mines, factories, natural history museums, private collections, universities and their professors. The death of his mother in 1762 having deprived him of his means of support, he went in 1763 on the invitation of the pastor of the Lutheran community, Anton Friedrich Büsching, the founder of the modern historic statistical method of geography, to teach natural history in the Lutheran gymnasium St. ...

Pooideae
The Pooideae are the largest subfamily of the grass family Poaceae, with about 4,000 species in 15 tribes and roughly 200 genera. They include some major cereals such as wheat, barley, oat, rye and many lawn and pasture grasses. They are often referred to as cool-season grasses, because they are distributed in temperate climates. All of them use the C3 photosynthetic pathway. The Pooideae are the sister group of the bamboos within the BOP clade, and are themselves subdivided into 15 tribes. Phylogeny Relationships of tribes in the Pooideae according to a 2017 phylogenetic In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups o ... classification, also showing the bamboos as sister group: References External links Poaceae subfamilies {{Poaceae-stub ...
