Ludwigia (plant)
''Ludwigia'' (primrose-willow, water-purslane, or water-primrose) is a genus of about 82 species of aquatic plants with a cosmopolitan distribution, cosmopolitan but mainly tropical distribution. Currently (2023), there is much debate among botanists and plant taxonomists as to the classification of many ''Ludwigia'' species. Botanists from the US Department of Agriculture are currently doing genetic analyses on plants from the Western US and South America to better classify members of this genus. The genus was named by Carl Linnaeus after Christian Gottlieb Ludwig (1709-1773). Fossil record The oldest known remains of the genus are known from Eckfelder Maar, Eckfelder maar in Germany, dating to the Eocene. ''Ludwigia'' pollen was also found associated with beetles belonging to the families Buprestidae and Scarabaeidae, suggesting that these flowers were likely pollinated by beetles rather than hymenopterans as is typical in modern species. A large number of fossil seeds of â ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, 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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Center For Biotechnology Information
The National Center for Biotechnology Information (NCBI) is part of the National Library of Medicine (NLM), a branch of the National Institutes of Health (NIH). It is approved and funded by the government of the United States. The NCBI is located in Bethesda, Maryland, and was founded in 1988 through legislation sponsored by US Congressman Claude Pepper. The NCBI houses a series of databases relevant to biotechnology and biomedicine and is an important resource for bioinformatics tools and services. Major databases include GenBank for DNA sequences and PubMed, a bibliographic database for biomedical literature. Other databases include the NCBI Epigenomics database. All these databases are available online through the Entrez search engine. NCBI was directed by David Lipman, one of the original authors of the BLAST sequence alignment program and a widely respected figure in bioinformatics. GenBank NCBI had responsibility for making available the GenBank DNA seque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ludwigia Helminthorrhiza
''Ludwigia helminthorrhiza'', known commonly as floating Ludwigia, originally known as Jussiaea natans ''Bonpl.'' or Jussiaea helminthorrhiza ''C. Martius'' is a herbaceous perennial plant of the family Onagraceae. Native to south Mexico, Colombia and South America, its habitat includes wet, swampy localities. Physiology ''Ludwigia helminthorrhiza'' grows from the water's edge into the water and along the stem and roots develops 1 - 1.2 cm long white rootlets which function as floating bodies to keep the main plant floating on the surface. At each nodus, the plant may develop roots, which may reach through the water to the bottom of the water. The flowers have white petals Petals are modified leaves that form an inner whorl surrounding the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''coroll ... and oval to almost round shaped leaves.http://eol.org ...

Ludwigia Grandiflora
''Ludwigia grandiflora'', the water primrose, is an aquatic plant of the order Myrtales. It is closely related and easily confused with '' Ludwigia hexapetala''. The two species can be distinguished at a chromosomal level, because ''L.grandiflora'' is hexaploid and ''L.hexapetala'' is decaploid. However, they can be distinguished morphologically. ''L.grandiflora'' has villous hairs, smaller flowers and smaller pollen grains. Some authorities consider that these differences are too slight to consider these different species and so separate these taxa as two varieties or two subspecies. Invasive species ''Ludwigia grandiflora'' has been listed on the List of Invasive Alien Species of Union concern since 2016 and in the United States it is on the South Carolina State-listed Noxious Weed list. It out-competes other plants by forming dense mats at the margins and in ponds. It is introduced to warm temperate areas of North America, Japan and Europe and has formed large stable popula ...

Ludwigia Glandulosa
''Ludwigia glandulosa'', the cylindricfruit primrose-willow, is an amphibious plant from southeast United States. It can grow partially or fully submerged. It grows very slowly and needs carbon dioxide in order to grow well. The leaves of this plant will turn greener if insufficient light is provided. Distribution and conservation status ''Ludwigia glandulosa'' can be found in wetland areas and roadside ditches throughout most of the southern states in North America. It is a threatened species in Indiana and endangered in Maryland. When including these wetland plant species, necessary protections may be restricted to the wetland and a buffer area. However, special precautions beyond the normal 100-foot buffer may be needed in order to protect the plants from invasive species and human activities. It is imperative that recommendations and guidance be done from the Maryland Department of Natural Resources before disturbance occurs. Habitat and ecology ''Ludwigia glandulosa'' is ...

Ludwigia Decurrens
''Ludwigia decurrens'' is a species of flowering plant in the evening primrose family known by the common names willow primrose and wingleaf primrose-willow. It is native to the central and eastern United States. This species is an annual herb that reaches up to tall, sometimes growing as a perennial by virtue of its partially woody stem. It has an erect form and a winged stem that is angled. The plant is glabrous. The linear leaves are alternately arranged. The sessile leaves are decurrent: they extend down along the stem at their bases. The flower has four yellow petals. The seed capsules may contain up to 1000 seeds per capsule. This plant grows in wet habitat types, often alongside ''Polygonum'' and ''Cyperus'' species. ''L. decurrens'' has become an invasive species in Africa and in Southeast Asia, where it frequently colonizes rice paddies and other wetlands. Invasion in anaerobic habitats is facilitated by the aerenchyma that enable willow primrose rhizomes to float ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
