Ernst Heinrich Friedrich Meyer
Ernst Heinrich Friedrich Meyer (1 January 1791 – 7 August 1858) was a German botanist and botanical historian. Born in Hanover, he lectured in Göttingen and in 1826 became a professor of botany at the University of Königsberg, as well as Director of the Botanical Garden. His botanical specialty was the Juncaceae, or family of rushes. His major work was the four-volume ''Geschichte der Botanik'' (“History of Botany,” 1854–57). His history covered ancient authorities such as Aristotle and Theophrastus, explored the beginnings of modern botany in the context of 15th- and 16th-century intellectual practice, and offered a wealth of biographical data on early modern botanists. Julius von Sachs pronounced him “no great botanist” but admitted that he “possessed a clever and cultivated intellect.” He died in Königsberg, East Prussia. In 1828, he was honoured by Swiss botanist Augustin Pyramus de Candolle who named a genus of plants from tropical South America after hi ...

Conserved Name
A conserved name or ''nomen conservandum'' (plural ''nomina conservanda'', abbreviated as ''nom. cons.'') is a scientific name that has specific nomenclatural protection. That is, the name is retained, even though it violates one or more rules which would otherwise prevent it from being legitimate. ''Nomen conservandum'' is a Latin term, meaning "a name to be conserved". The terms are often used interchangeably, such as by the ''International Code of Nomenclature for Algae, Fungi, and Plants'' (ICN), while the ''International Code of Zoological Nomenclature'' favours the term "''conserved name''". The process for conserving botanical names is different from that for zoological names. Under the botanical code, names may also be "suppressed", ''nomen rejiciendum'' (plural ''nomina rejicienda'' or ''nomina utique rejicienda'', abbreviated as ''nom. rej.''), or rejected in favour of a particular conserved name, and combinations based on a suppressed name are also listed as “''nom. re ...

Apocynaceae
Apocynaceae (from ''Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here. Many species are tall trees found in tropical forests, but some grow in tropical dry (xeric) environments. Also perennial herbs from temperate zones occur. Many of these plants have milky latex, and many species are poisonous if ingested, the family being rich in genera containing alkaloids and cardiac glycosides, those containing the latter often finding use as arrow poisons. Some genera of Apocynaceae, such as '' Adenium'', bleed clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
