Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss people, Swiss botany, botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. De Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vernon Heywood
Vernon Hilton Heywood (24 December 1927 – 17 September 2022) was a British biologist. He specialised in medicinal and aromatic plants, and the conservation of wild relatives of plants. Heywood was appointed lecturer at University of Liverpool, UK in 1955, promoted to senior lecturer in 1960 and to reader in 1963. He was awarded the second established Chair in Botany in 1964 and left Liverpool in 1968. He was Professor of Botany and Head of Department at the University of Reading until 1987 when he became founder and director of Botanic Gardens Conservation International (BGCI). In 1987 he was awarded the Linnean Medal of the Linnean Society of London. Planta Europa honored him with their Linnaeus award at their fifth conference, held in 2007 in Cluj Napoca. The book ''Taxonomy and Plant Conservation'' (Cambridge University Press, 2006, Etelka Leadlay and Stephen Jury, eds.) was dedicated as a tribute to Heywood in honor of his 75th birthday.

Asplenium
''Asplenium'' is a genus of about 700 species of ferns, often treated as the only genus in the family (biology), family Aspleniaceae, though other authors consider ''Hymenasplenium'' separate, based on molecular phylogenetic analysis of DNA sequences, a different chromosome count, and structural differences in the rhizomes. The type species for the genus is ''Asplenium marinum''. The most common vernacular name is spleenworts, applied to the more "typical" species. ''Asplenium nidus, A. nidus'' and several similar species are called bird's-nest ferns, the ''Camptosorus'' group is known as walking ferns, and distinct names are applied to some other particularly well-known species. Etymology From Neo-Latin, New Latin ''asplenium'' (“spleenworts”), Carolus Linnaeus, Linnaeus's adjustment of Latin ''asplenon'' (“spleenwort”), from Ancient Greek ἄσπληνον (''ásplēnon'', “spleenwort”), from ἀ- (''a-'', “un-”) + σπλήν (''splḗn'', “spleen”) + -ο� ...

Flora Of Southeastern Europe
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was ...
