Orchideae Genera
Orchideae is a tribe of orchids in the subfamily Orchidoideae. Historically, it was divided into 2 subtribes, Orchidinae and Habenariinae. The subtribe Orchidinae alone contains about 1,800 species. However, although some phylogenetic studies have established the monophyly of the subtribes, the generic boundaries are unclear, with many genera as traditionally circumscribed being paraphyletic or even polyphyletic. Species of genera such as ''Habenaria'' and '' Platanthera'' have been placed into both subtribes. A 2017 molecular phylogenetic study found that both subtribes did form clades, but did not formally recognize Habenariinae, because of missing genera and uncertainty over generic boundaries. The Asian species of Orchideae, in particular, have been subject to repeated changes of generic placement from 2012 onwards. As of 2017, Orchideae is divided into 6 subtribes: Brownleeinae, Pachitinae, Huttonaeinae, Orchidinae, Coryciinae, and Disinae. Subtribes Once divided in ...

Orchis Provincialis
''Orchis provincialis'', the Provence orchid, is a species of orchid in the genus ''Orchis''. Description ''Orchis provincialis'' is a herbaceous plant high. The 4-5 basal leaves are oblong-lanceolate, with a length of about 8 cm and arranged in a rosette, the color is green with purplish brown spots. The cauline leaves are sheathing the stem, with yellowish lanceolate bracts. The inflorescence comprises 5 to 30 small flowers. Their color varies from creamy white or pale yellow to various shades of pink and purple in some varieties. The lateral sepals are ovate and erect, the median sepal is slightly leaning forward. The labellum is trilobed, with small spots from orange to purple on the median lobe. The white spur is cylindrical and curved upward, longer than the ovary. The gynostegium is short, obtuse, with pale yellow pollen. This orchid blooms from March to June. Distribution The species has a Mediterranean distribution and it is widespread from north-western Afric ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree. History The theoretical frame ...

Anacamptis
''Anacamptis'' is a genus of flowering plants in the orchid family (Orchidaceae); it is often abbreviated as Ant in horticulture. This genus was established by Louis Claude Richard in 1817; the type species is the pyramidal orchid (''A. pyramidalis'') and it nowadays contains about one-third of the species placed in the "wastebin genus" ''Orchis'' before this was split up at the end of the 20th century,Bateman & Hollingsworth (2004) among them many that are of hybrid origin. The genus' scientific name is derived from the Greek word ''anakamptein'', meaning "to bend backwards". These terrestrial orchids occur on grasslands, limestone or chalk deposits, or on dunes in Eurasia, from the Mediterranean region to Central Asia. Systematics Except the pyramidal orchid (''A. pyramidalis''), all species of ''Anacamptis'' seem to form a clade around the green-veined orchid (''A. morio''). They have a diploid chromosome number of 32 or 36. A useful character for distinguishing ''Anacampt ...

Monophyly
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 taken ...
