Odontites Luteus
''Odontites luteus'' is a plant belonging to the genus ''Odontites'' in the family Orobanchaceae. Description ''Odontites luteus'' is an annual plant, hemiparasite A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants develop a specialized organ called the ..., 10 to 60 cm high. The leaves are linear, narrow and generally entire. The inflorescences are organized in unilateral clusters. The pubescent corolla, with ciliate-bearded margins, has a deep yellow color. The stamens are clearly prominent outside the corolla. The number of chromosomes of this species is 2n = 20. Habitat and distribution ''Odontites luteus'' is distributed in Europe and North Africa (subsp. ''reboudii''). It grows in steppes, garrigues and in the edge of dry forests. It prefers moderately dry soils, usually limestone, poor in clay, but always in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Von Linné
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Philippe De Clairville
Joseph Philippe de Clairville (1742 – 31 July 1830) was a notable French botanist and entomologist, who was mainly active in Switzerland. De Clairville’s collection of Coleoptera, his chief interest, is in the Natural History Museum in Basel. He was also interested in Diptera and Odonata. After his stay in Nyon and Bex in the French-speaking part of Switzerland, he moved to Winterthur in 1782, where he lived the most time until his death in 1830. De Clairville wrote ''Helvetische Entomologie'' published in Zürich , neighboring_municipalities = Adliswil, Dübendorf, Fällanden, Kilchberg, Maur, Oberengstringen, Opfikon, Regensdorf, Rümlang, Schlieren, Stallikon, Uitikon, Urdorf, Wallisellen, Zollikon , twintowns = Kunming, San Francisco Zürich ... in 1798, wrote ''Manuel d'herborisation en Suisse et en Valais'' published in 1811, and translated ''Naturgeschichte der Hof- und Stubenvögel'' by Johann Matthäus Bechstein into French under the titles ''Manu ...

Odontites
''Odontites'' is a genus of flowering plants in the family Orobanchaceae. Phylogeny The phylogeny of the genera of Rhinantheae has been explored using molecular characters. ''Odontites'' belongs to the core Rhinantheae. It is the sister genus to ''Bellardia'', and then to ''Tozzia'' and ''Hedbergia''. These taxa are closely related to the genus ''Euphrasia''. In turn, these five genera share phylogenetic affinities with ''Bartsia''. Conservation One of the ''Odontites'' species, ''O. granatensis'', endemic to the Sierra Nevada in Spain , image_flag = Bandera de España.svg , image_coat = Escudo de España (mazonado).svg , national_motto = ''Plus ultra'' (Latin)(English: "Further Beyond") , national_anthem = (English: "Royal March") , i ..., was so threatened that in 1993 only 1,500 plants survived in two locations. Due to conservation efforts the plant has made a comeback, numbering over 100,000 in 2006. References Oroban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orobanchaceae
Orobanchaceae, the broomrapes, is a family of mostly parasitic plants of the order Lamiales, with about 90 genera and more than 2000 species. Many of these genera (e.g., ''Pedicularis'', ''Rhinanthus'', ''Striga'') were formerly included in the family Scrophulariaceae ''sensu lato''. With its new circumscription, Orobanchaceae forms a distinct, monophyletic family. From a phylogenetic perspective, it is defined as the largest crown clade containing '' Orobanche major'' and relatives, but neither ''Paulownia tomentosa'' nor ''Phryma leptostachya'' nor '' Mazus japonicus''. The Orobanchaceae are annual herbs or perennial herbs or shrubs, and most (all except ''Lindenbergia'', ''Rehmannia'' and ''Triaenophora'') are parasitic on the roots of other plants—either holoparasitic or hemiparasitic (fully or partly parasitic). The holoparasitic species lack chlorophyll and therefore cannot perform photosynthesis. Description Orobanchaceae is the largest of the 20–28 dicot fami ...

Hemiparasite
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants develop a specialized organ called the haustorium, which penetrates the host plant, connecting them to the host vasculature – either the xylem, phloem, or both. For example, plants like ''Striga'' or ''Rhinanthus'' connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like ''Cuscuta'' and some members of ''Orobanche'' connect to both the xylem and phloem of the host. This provides them with the ability to extract water and nutrients from the host. Parasitic plants are classified depending on the location where the parasitic plant latches onto the host (root or stem), the amount of nutrients it requires, and their photosynthetic capability. Some parasitic plants can locate their host plants by detecting volatile chemicals in the air or soil given ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromosome Number
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle.
