× Codonatanthus
''Codonanthe'' is a genus of mainly Epiphyte, epiphytic plants in the family Gesneriaceae, endemic to the Atlantic Forest of Brazil. The botanical name comes from the Ancient Greek for 'bellflower'. They have white or pale pink flowers and somewhat fleshy leaves. In 2013, the genus was reduced in size when more than half of the species were transferred to ''Codonanthopsis''. They can be grown as houseplants, particularly in hanging baskets. Artificial crosses with ''Nematanthus'' hybrids have produced the Hybrid name, hybrid genus × ''Codonatanthus''. Description ''Codonanthe'' species are subshrubs, generally growing as epiphytes, occasionally on rocks. Unlike ''Codonanthopsis'' species, they never grow in ant gardens. They have stems with few branches, which may be upright, creeping or hanging, and often produce roots along their length (adventitious roots). The leaves have a short or very short Petiole (botany), petiole (stalk), and are fleshy, with either smooth or hairy sur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), 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. General characteristics Inflorescences are described by many different charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Gesnerioideae
The Gesnerioideae are a subfamily of plants in the family Gesneriaceae: based on the type genus ''Gesneria''. Although genera typically originate in the New World, some species have become widely distributed as ornamental plants. Description Gesnerioideae is one of two main subfamilies in the Gesneriaceae, the other being Didymocarpoideae. (The third subfamily, Sanangoideae, contains only the genus ''Sanango''.) Gesnerioideae seedlings have normal cotyledons of the same size and shape (isocotylous), whereas the cotyledons of Didymocarpoideae are usually, but not always, eventually different in size and shape (anisocotylous). Gesnerioideae flowers usually have four fertile stamens, rarely two or five. In other respects, Gesnerioideae species are very variable. The Ovary (botany), ovary may be superior, semi-inferior or inferior, and the fruit takes various forms. Taxonomy The original use of the name for the subfamily is attributed to Gilbert Thomas Burnett in 1835. Burnett divide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monophyly
In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent common ancestor (or more precisely an ancestral population), i.e. excludes non-descendants of that common ancestor # the grouping contains all the descendants of that common ancestor, without exception Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic'' grouping meets 1. but not 2., thus consisting of the descendants of a common ancestor, excepting one or more monophyletic subgroups. A ''polyphyletic'' grouping meets neither criterion, and instead serves to characterize convergent relationships of biological features rather than genetic relationships – for example, night-active primates, fruit trees, or aquatic insects. As such, these characteristic features of a polyphyletic grouping are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetics, phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in Taxonomy (biology), taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tre ...

Johannes Von Hanstein
Johannes Ludwig Emil Robert von Hanstein (15 May 1822 – 27 August 1880) was a German botanist who was a native of Potsdam. He attended classes at the ''Gärtnerlehranstalt'' (Institute of Horticulture) in Potsdam, and later studied sciences in Berlin, obtaining his doctorate in 1848. In 1855 he was a lecturer of botany at the University of Berlin, and six years later became curator of the royal herbarium. In 1865 he was appointed professor of botany at the University of Bonn and director of the botanical garden. Hanstein is remembered for studies in plant anatomy and morphology. In 1868 he introduced the " histogen theory" to explain shoot apex behaviour in plants. With his close friend, Nathanael Pringsheim (1823–1894), he conducted pioneer research on the fertilization process in ferns. The plant genus '' Hansteinia'' of the family Acanthaceae is named after him. Gallery File:Capsella bursa-pastoris, kiembol (Hanstein).jpg, ''Capsella bursa-pastoris'' drawing by Johann ...

Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
