Question

Which genus has the most species?

Answer 1

A genus is a taxonomic rank used to classify living and extinct species, as well as viruses, in biology. Genus is placed above species and below family in the biological categorization hierarchy. The genus name is the first part of the binomial species name for each species within the genus in binomial nomenclature. Taxonomists determine the composition of a genus.

Complete answer:
In the biological classification system, a species of organism is considered the most basic unit or category. A genus is a collection of closely related species that have a common ancestor. A genus is one of numerous hierarchical taxonomic groups.
The legume genus Astragalus is reported to have the biggest number of species among flowering plants, with about three thousand species. When it comes to the genus with the most species, however, there is some debate. However, when divided into categories, such as flowering plants, Astragalus has a wide range of species.
Astragalus is a vast genus of herbs and small shrubs belonging to the legume family Fabaceae and the subfamily Faboideae, with over three thousand species. In terms of the number of species described, it is the largest genus of plants. The genus is native to the Northern Hemisphere’s temperate zones. Milkvetch, locoweed, and goat’s-thorn are all common names for this plant. Although certain pale-flowered vetches have a similar appearance to Astragalus , they are more vine-like.

Note:

In the United States, this herbal supplement is commonly used as an immune booster to prevent common colds and upper respiratory infections. Astragalus is also thought to be beneficial in the treatment of cardiac problems.
