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 Phylogenetics, phylogenetic studies have established the monophyly of the subtribes, the generic boundaries are unclear, with many genera as traditionally Circumscription (taxonomy), circumscribed being Paraphyly, paraphyletic or even Polyphyly, polyphyletic. Species of genera such as ''Habenaria'' and ''Platanthera'' have been placed into both subtribes. A 2017 Molecular phylogenetics, 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, Pachitina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 phylogenetics, 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 (biology), 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 tre ...

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 ''Anacam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monophyly
In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent common ancestor (or more precisely an ancestral population), i.e. excludes non-descendants of that common ancestor # the grouping contains all the descendants of that common ancestor, without exception Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic'' grouping meets 1. but not 2., thus consisting of the descendants of a common ancestor, excepting one or more monophyletic subgroups. A ''polyphyletic'' grouping meets neither criterion, and instead serves to characterize convergent relationships of biological features rather than genetic relationships – for example, night-active primates, fruit trees, or aquatic insects. As such, these characteristic features of a polyphyletic grouping are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flowers Of India 828
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants (angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same flower ...
