Verbena
''Verbena'' (), also known as vervain or verveine, is a genus in the family Verbenaceae. It contains about 150 species of annual and perennial herbaceous or semi-woody flowering plants. The majority of the species are native to the Americas and Asia; however, '' Verbena officinalis'', the common vervain or common verbena, is the type species and native to Europe. Naming In English, the name ''Verbena'' is usually used in the United States and the United Kingdom; elsewhere, the terms ''verveine'' or ''vervain'' are in use. Description Verbena is a herbaceous flowering plant, belonging to the Verbenaceae family, and may be annual or perennial depending on the species. The leaves are usually opposite, simple, and in many species hairy, often densely so. The flowers are small, with five petals, and borne in dense spikes. Typically some shade of blue, they may also be white, pink, or purple, especially in cultivars. The genus can be divided into a diploid North American and a p ...

Verbena Officinalis
''Verbena officinalis'', the common vervain or common verbena, is a perennial herb native to Europe. It grows up to high, with an upright habitus. The lobed leaves are toothed, and the delicate spikes hold clusters of two-lipped mauve flowers. This plant prefers limey soils; it is occasionally grown as an ornamental plant but perhaps more often for the powerful properties some herbalists ascribe to it. Propagation is by root cuttings or seed. It is widely naturalised outside its native range, for example in North America. Common names and taxonomy It is known also as simpler's joy or holy herb, or more ambiguously as mosquito plant or wild hyssop. The common name blue vervain is also sometimes used, but also refers to '' V. hastata''. Being the only member of its genus in much of its range, it is also simply known as vervain locally. The common names of ''V. officinalis'' in many Central and Eastern European languages often associate it with iron, for example: * ''Echtes Eis ...

Verbenaceae
The Verbenaceae ( ), the verbena family or vervain family, is a family of mainly tropical flowering plants. It contains trees, shrubs, and herbs notable for heads, spikes, or clusters of small flowers, many of which have an aromatic smell. The family Verbenaceae includes 32 genera and 800 species. Phylogenetic studies have shown that numerous genera traditionally classified in Verbenaceae belong instead in Lamiaceae. The mangrove genus ''Avicennia'', sometimes placed in the Verbenaceae or in its own family, Avicenniaceae, has been placed in the Acanthaceae. Economically important Verbenaceae include: * Lemon verbena (''Aloysia triphylla''), grown for aroma or flavoring * Verbenas or vervains (''Verbena''), some used in herbalism, others grown in gardens Taxonomy Tribes and genera in the family and their estimated species numbers: Casselieae (Schauer) Tronc. * ''Casselia'' Nees & Mart. - 6 species * ''Parodianthus'' Tronc. - 2 species * ''Tamonea'' Aubl. - 6 species C ...

Glandularia Bipinnatifida
''Verbena bipinnatifida'', commonly called Dakota mock vervain, prairie verbena, and Moradilla, among others, is a species of flowering plant in the verbena family Verbenaceae. Description ''Verbena bipinnatifida'' is an herbaceous or semi-woody perennial. It produces pink or purple flowers primarily in the spring, but can bloom anytime throughout the growing season. Its leaves are finely dissected, into segments that are 1–4 mm wide. It can be distinguished from the similar-looking '' Verbena tenera'' by its long flower bracts, and wider leaf segments. Distribution and habitat It is native to North America, where its natural range extends from the United States south to Nicaragua. In the United States, it is found primarily in the Great Plains and in the Blackland Prairies of the Southeast. Elsewhere in North America, it is occasionally found as a non-persisting waif A waif (from the Old French , )Dictionary.com Unabridged (v 1.1). Random House, Inc. http://dictionary ...

Karyotype
A karyotype is the general appearance of the complete set of chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes. Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of chromosomes and any abnormalities. A karyogram or idiogram is a graphical depiction of a karyotype, wherein chromosomes are generally organized in pairs, ordered by size and position of centromere for chromosomes of the same size. Karyotyping generally combines light microscopy and photography in the metaphase of the cell cycle, and results in a photomicrographic (or simply micrographic) karyogram. In contrast, a schematic karyogram is a designed graphic representation of a karyotype. In schematic karyograms, just one of the sister chromatids of each chromosome is generally shown for brevity, and in reality they are generally so close together that they look as ...

Computational Phylogenetics
Computational phylogenetics, phylogeny inference, or phylogenetic inference focuses on computational and optimization algorithms, Heuristic (computer science), heuristics, and approaches involved in Phylogenetics, phylogenetic analyses. The goal is to find a phylogenetic tree representing optimal evolutionary ancestry between a set of genes, species, or taxa. Maximum likelihood estimation, Maximum likelihood, Maximum parsimony (phylogenetics), parsimony, Bayesian inference in phylogeny, Bayesian, and minimum evolution are typical optimality criteria used to assess how well a phylogenetic tree topology describes the sequence data. Nearest Neighbour Interchange (NNI), Subtree Prune and Regraft (SPR), and Tree Bisection and Reconnection (TBR), known as tree rearrangements, are deterministic algorithms to search for optimal or the best phylogenetic tree. The space and the landscape of searching for the optimal phylogenetic tree is known as phylogeny search space. Maximum Likelihood (al ...
