Koenigia Hedbergii
:Koenigia'' as described by Philibert Commerçon is a synonym of ''Dombeya. ''Koenigia'' is a genus of plants in the family Polygonaceae. The genus ''Aconogonon'' has been merged into ''Koenigia''. Description Species of ''Koenigia'' are annual or perennial herbaceous plants, growing from taproots. The flowers are arranged in terminal or axillary inflorescences. The flowers have pale tepals: white, greenish to yellowish white or pink. The seeds are borne in achenes that are usually brown or black in colour and not winged. Taxonomy The genus ''Koenigia'' was erected by Carl Linnaeus in 1767, initially for the type species ''Koenigia islandica''. The boundaries between genera in the family Polygonaceae, and the relationships among them, have long been a problem. At one time, many species were placed in the genus ''Polygonum''. ''Koenigia'' is placed in the subfamily Polygonoideae, tribe Persicarieae, whose taxonomic history has been described as "exceptionally convoluted, even by ...

Philibert Commerçon
Philibert Commerson (; 18 November 1727 – 14 March 1773), sometimes spelled Commerçon by contemporaries, was a French naturalist, best known for accompanying Louis Antoine de Bougainville on his voyage of circumnavigation in 1766–1769. Biography Commerson was born at Châtillon-les-Dombes in France. He studied in Montpellier, and for a time was a practicing physician. He was in contact with Carl Linnaeus, who encouraged him to study fish of the Mediterranean. Commerson returned to live at Châtillon-les-Dombes, where he occupied himself in creating a botanical garden in 1758. After the death of his wife in 1764, he moved to Paris. In 1766, Commerson joined Bougainville on his voyage of circumnavigation after being recommended for the position of naturalist by the Paris Academy of Sciences. He had previously drawn up an extensive programme of nature studies for the Marine Ministry, in which he elaborated the "three natural kingdoms" which a naturalist should investiga ...

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 ...

Koenigia Davisiae
''Koenigia davisiae'' is a flowering plant in the knotweed family that is known by the common names Davis' knotweed or Newberry knotweed. Distribution ''Koenigia davisiae'' is native to the western United States from Washington, Oregon, and central and northern California (northern Coast Ranges and northern Sierra Nevada). There are also isolated populations in central Idaho. It grows in high mountain habitat, such as talus and fellfields. Description ''Koenigia davisiae'' is a perennial herb producing a decumbent or upright stem from a woody caudex, growing to a maximum erect height near 40 centimeters (3 feet). Stems may be pale green to red in color. The leaves are oval and pointed or widely-lance-shaped to somewhat triangular, yellowish or pale green and waxy, slightly hairy, or smooth in texture. At the base of each leaf is a thin reddish sheath formed from the leaf's stipules which is known as the ochrea An ochrea (Latin ''ocrea'', greave or protective legging), also ...

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images. See also *Australian Plant Name Index *Convention on Biological Diversity *World Flora Online *Tropicos Tropicos is an online botanical database containing taxonomic information on plants, mainly from the Neotropical realm (Central, and South America).
