Tribes are a taxonomic rank that falls between family and genus. They can be split into smaller related groups called subtribes. Tribes are mainly, though not always, used in botany to classify plants. The true grass family is divided into many subfamiles and then into tribes, one of which is bamboo. The insect world also uses tribes as a classification rank, for example, Bombini is the tribe of bumblebees.
In biological classification, rank is the level in a taxonomic hierarchy. Examples of taxonomic ranks are species, genus, family, and class. Each rank subsumes under it a number of less general categories. The rank of species, and specification of the genus to which the species belongs is basic, which means that it may not be necessary to specify ranks other than these.
