Ludwigia (plant)
''Ludwigia'' (primrose-willow, water-purslane, or water-primrose) is a genus of about 82 species of aquatic plants native to Central and South America with a cosmopolitan but mainly tropical distribution. At current, 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), a German botanist, who was apparently not amused by this honour. Fossil record A large number of fossil seeds of †''Ludwigia collinsoniae'' and †''Ludwigia corneri'' have been described from middle Miocene strata of the Fasterholt area near Silkeborg in Central Jutland, Denmark. Selected species Listed from the NCBI The National Center for Biotechnology Information (NCBI) is part of the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
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 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ludwigia Inclinata
''Ludwigia inclinata'' is a highly variable herb from Central and South America, usually found growing emersed or submersed on the beds of dried ponds or lakes, either submerged or with emergent stems. The verticillate forms, of which several are known, are among the most highly prized aquarium plants in the trade. They include ''Ludwigia inclinata var. verticillata 'Pantanal and ''Ludwigia inclinata var. verticillata 'Cuba. When grown to its full height, ''Ludwigia inclinata var. verticillata 'Pantanal is one of the most beautiful stem plants. Description Ludwigia Inclinata is a fragile plant with leaves that are long, narrow, and very colorful. They transition from green at the base to orange/yellow with deep red on the crown. The yellow and red leaves that a dramatic contrast to the green foliage. Inclinata plants have oblong, rounded leaves with a wavy texture that grow in opposite pairs along the length of the stem. Ludwigia Inclinata prefers medium to high light. Consist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ludwigia Hyssopifolia
''Ludwigia hyssopifolia'', called seedbox and linear leaf water primrose, is a species of flowering plant in the genus '' Ludwigia'', native to the New World Tropics and widely introduced to the rest of the world's tropics. A serious weed of rice paddies, a single plant can produce 250,000 seeds. References hyssopifolia Plants described in 1957 {{Myrtales-stub ...

Ludwigia Hexapetala
''Ludwigia hexapetala'', the water primrose, is a herbaceous perennial plant of the family Onagraceae. Native to Central and South America, its habitat includes the margins of lakes, ponds, ditches, and streams. Its stems may be immersed or fully emergent. It is a noxious invader of aquatic ecosystems in North America. Habitat ''Ludwigia hexapetala'' is native to Latin America. It occurs naturally in swampier regions, such as those of lakes, ponds, and other areas of low intensity/stagnant water. It grows in mats of up to three feet tall, and in doing so, it crowds and/or shades out the other, more native species. The plant is known to inhabit the Southeast United States, Midwest United States, Pacific Coast, and parts of New England New England is a region comprising six states in the Northeastern United States: Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. It is bordered by the state of New York (state), New York to the west and by the Ca ... [...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 surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually ... and oval to almost round shaped leaves.http://eol.o ...

Ludwigia Grandiflora
''Ludwigia grandiflora'', commonly referred to as 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 In 2016, following the EU Regulation 1143/2014 on Invasive Alien Species (IAS), the European Commission published a first list of 37 IAS of Union concern. The list was first updated in 2017 and comprised 49 species. Since the second update in 201 ... since 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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'' i ...

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 floa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
