Cordaitales
Cordaitales are an extinct order of gymnosperms, known from the early Carboniferous to the late Permian. Many Cordaitales had elongated strap-like leaves, resembling some modern-day conifers of the Araucariaceae and Podocarpaceae. They had cone-like reproductive structures reminiscent of those of modern conifers. Some Cordaitales formed large trees that seem to have been particularly abundant on drier ground, in tropical environments. Also, some tall trees but also shrubby and mangrove-like species of Cordaitales seem to have grown in the Carboniferous coal swamps. Cordaitales were also abundant during the Permian. Common genera from the Carboniferous include '' Mesoxylon'' and '' Cordaixylon''. Other genera are '' Noeggerathiopsis'' and '' Sumaropsis''. Features of the female cone ( megastrobilus) of the members of Cordaitales indicate that the cone scales, possessed by themselves and their descendants, may correspond to short shoot In botany, a plant shoot consists of any p ...

Cordaites Lungatus
''Cordaites'' is an important genus of extinct gymnosperms which grew on wet ground similar to the Everglades in Florida. Brackish water mussels and crustacea are found frequently between the roots of these trees. The fossils are found in rock sections from the Upper Carboniferous () of the Dutch - Belgian - German coal area. A number of many noteworthy types from this line are: * ''Cordaites principalis'' * ''Cordaites ludlowi'' (named after Ludlow, a coal area in England) * ''Cordaites hislopii''. Found in Paleorrota geopark in Brazil. In contrast to many other plants, fossilized ''Cordaites'' seeds are not rare, because they are rather large (up to 10 mm); those seeds are named ''Cordaicarpus ''Cordaicarpus'' is a form genus named by ''Geinitz'' (1862) and redefined by ''Seward'' (1917) to avoid confusion with another genus and to establish that the genus refers only seeds.

Cordaicarpus
''Cordaicarpus'' is a form genus named by ''Geinitz'' (1862) and redefined by ''Seward'' (1917) to avoid confusion with another genus and to establish that the genus refers only seeds. ''Seward'' defined the differences between ''Cordaicarpus'' and ''Samaropsis''. Location In Brazil, the fossil species ''C. brasilianus'', ''C. fanatinensis'', and ''C. truncata'' are located in outcrop ''Morro Papaléo'' in the city of Mariana Pimentel. The species ''C. cerronegrensisi'' was located in outcrop ''Mina Faxinal'' in the city of Arroio dos Ratos. They are in geopark Paleorrota in Rio Bonito Formation and date from the Sakmarian stage of the Permian Period The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya.

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Conifer
Conifers are a group of conifer cone, cone-bearing Spermatophyte, seed plants, a subset of gymnosperms. Scientifically, they make up the phylum, division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class (biology), class, Pinopsida. All Neontology, extant conifers are perennial plant, perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include Cedrus, cedars, Pseudotsuga, Douglas-firs, Cupressaceae, cypresses, firs, junipers, Agathis, kauri, larches, pines, Tsuga, hemlocks, Sequoioideae, redwoods, spruces, and Taxaceae, yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecology, ecologically important. They are the dominant plants over large areas of land, most ...

August Carl Joseph Corda
August Carl Joseph Corda (1809–1849) was a Czech physician and mycologist. This botanist is denoted by the author abbreviation when citing a botanical name. Early life and education Corda was born in Reichenberg (now Liberec), Bohemia on November 15, 1809. Corda's father was a textile seller. Both of Corda's parents died suddenly only a few weeks following his birth, and Corda was raised by his grandmother, attending the Normale School in Reichenberg. Corda's grandmother died in 1819 and Corda was sent to live with an "unacquainted family" for two years during which time he did not receive schooling. Two years later, Corda was transferred to the care of an uncle in Prague where he attended the "Lyceum of New Prague". As a result of family difficulties, Corda left the Lyceum in 1824 to attend polytechnical school. There, he studied physics under Franz Ignatz Cassian Hallaschka, chemistry under Josef Johann Steinmann, mineralogy under Franz Xaver Zippe, and botany under Ign ...
