Schismus Barbatus
''Schismus barbatus'' is a species of grass known as common Mediterranean grass and kelch-grass. It is native to Eurasia, and it is also known as an introduced species in the southwestern United States. It grows in many habitats, including disturbed areas. It is an annual grass growing in small clumps. The stems grow up to 27 centimeters long and are lined with threadlike leaves.

Pehr Löfling
Pehr Löfling (31 January 1729 – 22 February 1756) was a Swedish botanist and an apostle of Carl Linnaeus. Biography Löfling was born in Tolvfors Bruk, Gävle, Sweden. He studied at the University of Uppsala where he attended courses taught by Carl Linnaeus. When the Spanish ambassador asked Linnaeus to select a botanist for service in the American colonies, the professor at once named Loefling. He went to Spain in 1751 to learn Spanish, and then embarked with other scientists for South America in February 1754. The Treaty of Madrid (13 January 1750) had fixed the colonial borders of Spain and Portugal. In Cumaná, Venezuela (then a Spanish colony) Löfling joined a project to demarcate the border with Brazil, the ''Expedicion de Limites al Orinoco''. He was put in charge of a natural history department evaluating the resources of the region. Assisted by two young Spanish doctors, he was involved in the expedition for the remainder of his life. He died in a remote mission ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ...

Albert Thellung
Albert Thellung (12 May 1881 – 26 June 1928) was a Swiss botanist. He was a professor at the University of Zürich. The Austrian botanist Otto Stapf named the plant genus ''Thellungia'' of the grass family, Poaceae, after him, and Otto Eugen Schulz named the genus '' Thellungiella'' (family Brassicaceae Brassicaceae () or (the older) Cruciferae () is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The le ...) in his honor. Thellung made contributions to the third (1909–14) and fourth (1923) editions of Schinz and Keller's ''Flora der Schweiz''.Biodiversity Heritage Library

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, ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ...

Inflorescence
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. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...
