Cardamine Incisa
''Cardamine incisa'' is a species of flowering plant in the mustard family Brassicaceae. Taxonomy ''Cardamine incisa'' was first described as ''Dentaria incisa'' by Edwin Hubert Eames in 1903. However, the name ''Dentaria incisa'' is an illegitimate name since the binomial name ''Dentaria incisa'' was already in use at the time Eames published his description. The American botanist Nathaniel Lord Britton corrected this oversight by describing ''Dentaria incisifolia'' in 1905, but by that time, a valid description for ''Cardamine incisa'' had already been provided by the German botanist Karl Moritz Schumann in 1904. Therefore, the correct name for this taxon is ''Cardamine incisa'' , while the other two names are synonyms. In recognition of Eames' contribution, the taxon is sometimes referred to as Eames' toothwort. ''Cardamine incisa'' is a member of the ''Cardamine concatenata'' alliance, a monophyletic group of eastern North American species that includes '' Cardamine ...

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cardamine
''Cardamine'' is a large genus of flowering plants in the mustard family, Brassicaceae, known as bittercresses and toothworts. It contains more than 200 species of annuals and perennials. Species in this genus can be found worldwide, except the Antarctic, in diverse habitats. The name ''Cardamine'' is derived from the Greek ''kardaminē'', water cress, from ''kardamon'', pepper grass. Description The leaves can have different forms, from minute to medium in size. They can be simple, pinnate or bipinnate. They are basal and cauline (growing on the upper part of the stem), with narrow tips. They are rosulate (forming a rosette). The blade margins can be entire, serrate or dentate. The stem internodes lack firmness. The nearly radially symmetrical flowers grow in a racemose many-flowered inflorescence or in corymbs. The white, pink or purple flowers are minute to medium-sized. The petals are longer than the sepals. The fertile flowers are hermaphroditic. Taxonomy The genus ''Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have t ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
