The Anacardiaceae, commonly known as the cashew family [1] or sumac family, are a family of flowering plants, including about 83 genera with about 860 known species. [2] Members of the Anacardiaceae bear fruits that are drupes and in some cases produce urushiol , an irritant .
Rhizobium forms a symbiotic relationship with certain plants, such as legumes, fixing nitrogen from the air into ammonia, which acts as a natural fertilizer for the plants. The Agricultural Research Service is conducting research involving the genetic mapping of various rhizobial species with their respective symbiotic plant species, like ...
Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, "plant systematics" involves relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens. The precise relationship between taxonomy ...
A taxon is usually assigned a rank when it is given its formal name. The basic ranks are species and genus. When an organism is given a species name it is assigned to a genus, and the genus name is part of the species name. The species name is also called a binomial, that is, a two-term name.
His magnum opus De Plantis came out in 1583, and described more than 1,500 plant species. [43] [44] Two large plant families that he first recognized are in use: the Asteraceae and Brassicaceae. [45] In the 17th century, John Ray (England, 1627–1705) wrote many important taxonomic works. [37]
Two of his works, the first edition of the Species Plantarum (1753) for plants and the tenth edition of the Systema Naturae (1758), are accepted as part of the starting points of nomenclature; his binomials (names for species) and generic names take priority over those of others. [1]
The key activities of cultivated plant taxonomy relate to classification and naming (nomenclature).The rules associated with naming plants are separate from the methods, principles or purposes of classification, except that the units of classification, the taxa, are placed in a nested hierarchy of ranks – like species within genera, and genera within families.
