In biological classification, rank is the relative level of a group of organisms (a taxon) in a taxonomic hierarchy. Examples of taxonomic ranks are species, genus, family, class, kingdom, etc. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms.xamples of taxonomic ranks are species, genus, family, class, kingdom, etc. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms.
John Ray (1686â1704) provided the first definition of  species  in his  Historia Plantarum : a species is a set of individuals who give rise through reproduction to new individuals similar to themselves. In 1753 Carl Linnaeus published  Species Plantarum , which included information on about 5,900 plants.
