Namacodon
''Namacodon schinzianum'' is a species of plant in the family Campanulaceae, endemic to Namibia. It was originally described by Friedrich Markgraf Friedrich Markgraf (1 February 1897 in Berlin-Friedenau – 8 March 1987 in Zurich) was a German botanist. Life and work After secondary school, Markgraf studied biology at the Friedrich Wilhelm University Berlin. In 1922 he was awarded a ... in 1941 as ''Prismatocarpus schinzianus'', but was moved to its own genus, ''Namacodon'' by Mats Thulin in 1974. It is known from fewer than 20 populations, all among rocks at altitude.

Campanulaceae
The family Campanulaceae (also bellflower family), of the order Asterales, contains nearly 2400 species in 84 genera of herbaceous plants, shrubs, and rarely small trees, often with milky sap. Among them are several familiar garden plants belonging to the genera '' Campanula'' (bellflower), ''Lobelia'', and ''Platycodon'' (balloonflower). ''Campanula rapunculus'' (rampion or r. bellflower) and ''Codonopsis lanceolata'' are eaten as vegetables. ''Lobelia inflata'' (indian tobacco), '' L. siphilitica'' and '' L. tupa'' (devil's tobacco) and others have been used as medicinal plants. ''Campanula rapunculoides'' (creeping bellflower) may be a troublesome weed, particularly in gardens, while ''Legousia'' spp. may occur in arable fields. Most current classifications include the segregate family Lobeliaceae in Campanulaceae as subfamily Lobelioideae. A third subfamily, Cyphioideae, includes the genus ''Cyphia'', and sometimes also the genera ''Cyphocarpus'', ''Nemacladus'', ''Parishell ...

Friedrich Markgraf
Friedrich Markgraf (1 February 1897 in Berlin-Friedenau – 8 March 1987 in Zurich) was a German botanist. Life and work After secondary school, Markgraf studied biology at the Friedrich Wilhelm University Berlin. In 1922 he was awarded a Ph.D. for a thesis on the subject of a botanic-ecological study of the Bredower forest near Berlin. After his habilitation he became first a professor of botany at the Friedrich Wilhelm University in Berlin and then at the Ludwig Maximilian University of Munich and director of the Botanical Garden Munich-Nymphenburg (1956-1958). Markgraf was also visiting professor of botany at the University of Zurich. During his teaching and research activities, he was primarily concerned with questions of botanical systematics, plant morphology and phytogeography and he also undertook research while travelling in the Mediterranean. In particular he made an important start on the study of the local flora of Albania. He acted as the Regional Adviser o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Namibia
Namibia (, ), officially the Republic of Namibia, is a country in Southern Africa. Its western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although Kazungula, it does not border Zimbabwe, less than 200 metres (660 feet) of the Botswanan right bank of the Zambezi, Zambezi River separates the two countries. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek. Namibia is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU) and the Commonwealth of Nations. The driest country in sub-Saharan Africa, Namibia has been inhabited since pre-historic times by the San people, San, Damara people, Damara and Nama people. Around the 14th century, immigration, immigrating Bantu peoples arrived as part of the Bantu expansion. Since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Systematic Botany
Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, "plant systematics" involves relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens. The precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed. Plant taxonomy is well known for being turbulent, and traditionally not having any close agreement on circumscription and placement of taxa. See the list of systems of plant taxonomy. Background Classification systems serve the purpose of grouping organisms by characteristics common to each group. Plants are distinguished from animals by various trai ...

Monotypic Campanulaceae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

Least Concern Plants
Comparison is a feature in the morphology or syntax of some languages whereby adjectives and adverbs are inflected to indicate the relative degree of the property they define exhibited by the word or phrase they modify or describe. In languages that have it, the comparative construction expresses quality, quantity, or degree relative to ''some'' other comparator(s). The superlative construction expresses the greatest quality, quantity, or degree—i.e. relative to ''all'' other comparators. The associated grammatical category is degree of comparison. The usual degrees of comparison are the ''positive'', which simply denotes a property (as with the English words ''big'' and ''fully''); the ''comparative'', which indicates ''greater'' degree (as ''bigger'' and ''more fully''); and the ''superlative'', which indicates ''greatest'' degree (as ''biggest'' and ''most fully''). Some languages have forms indicating a very large degree of a particular quality (called ''elative'' in Semit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
