Anagallis Arvensis 2
''Anagallis'' is a genus of about 20–25 species of flowering plants in the family Primulaceae, commonly called pimpernel. The scarlet pimpernel referred to in literature is part of this genus. The botanical name is from the Greek ( 'again') and ( 'to delight in'), and it refers to the opening and closing of the flowers in response to environmental conditions. These are annual or perennial plants, growing in tufts on weedy and uncultivated areas. The stems are prostrate or decumbent. The leaves are opposite, rarely whorled, and sometimes with a few alternate leaves at the end of the stem. They are usually ovate in shape with a cordate base. Some of the species produce flowers of various colors. The flowers are radially symmetrical and have 5 sepals. The corolla consists of a short tube and 5 lobes. The tube may be so short that the lobes appear to be separate petals. They are usually solitary in the leaf axils, but sometimes are on short spikes at the end of the stem. Pimpe ...

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] |
APG III System
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families followi ...

Flora Of North America
The ''Flora of North America North of Mexico'' (usually referred to as ''FNA'') is a multivolume work describing the native plants and naturalized plants of North America, including the United States, Canada, St. Pierre and Miquelon, and Greenland. It includes bryophytes and vascular plants. All taxa are described and included in dichotomous keys, distributions of all species and infraspecific taxa are mapped, and about 20% of species are illustrated with line drawings prepared specifically for FNA. It is expected to fill 30 volumes when completed and will be the first work to treat all of the known flora north of Mexico; in 2015 it was expected tha the series would conclude in 2017. Twenty-nine of the volumes have been published as of 2022. Soon after publication, the contents are made available online. FNA is a collaboration of about 1,000 authors, artists, reviewers, and editors from throughout the world. Reception The series has been praised for "the comprehensive treatme ...

Anagallis Minima
''Lysimachia minima'' (chaffweed) is a 1-4 inch (2–10 cm) perennial herb in the primula family (Primulaceae). A cosmopolitan species, this small plant is native widely across North America and Eurasia. It can be found growing in moist soils and seasonal pools.

Anagallis Caerulea
''Lysimachia foemina'' is commonly known as blue pimpernel or poor man's weatherglass, and was formerly called ''Anagallis foemina''. It is a low-growing annual herbaceous plant in the genus ''Lysimachia'' of the family Primulaceae. In a comparison of DNA sequences, ''L. foemina'' was shown to be most closely related to ''L. monelli''. It had been thought by many to be closest to '' L. arvensis'', and some authors had even included ''L. foemina'' as a subspecies of ''L. arvensis'', as ''Anagallis arvensis'' subsp ''foemina''. These three species (''L arvensis'', ''L foemina'' and ''L monelli'') were among several transferred from ''Anagallis'' to ''Lysimachia'' in a 2009 paper. Etymology The previous genus name ''Anagallis'' derives from the Greek words ' meaning "again" and ' meaning "to delight in", possibly referring to the fact that these plants produce flowers twice in a year and the flowers open whenever the sun strikes them. The species epithet ' means "female" and refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lysimachia Serpyllifolia
''Lysimachia'' () is a genus consisting of 193 accepted species of flowering plants traditionally classified in the family Primulaceae. Based on a molecular phylogenetic study it was transferred to the family Myrsinaceae, before this family was later merged into the Primulaceae. Characteristics ''Lysimachia'' species often have yellow flowers, and grow vigorously. They tend to grow in damp conditions. Several species within ''Lysimachia'' are commonly called loosestrife, although this name is also used for plants within the genus ''Lythrum''. The genus is named in honor of Lysimachus, a king of ancient Sicily, who is said to have calmed a mad ox by feeding it a member of the genus. ''Lysimachia'' species are used as food plants by the larvae of some butterflies and moths, including the dot moth, grey pug, lime-speck pug, small angle shades, and v-pug. Specialized pollinators Bees of the genus ''Macropis'' are specialized to pollinate oil-producing ''Lysimachia'' plants. T ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...
