Raphanus is a genus within the flowering plant family Brassicaceae. Two or three species are currently classified in Raphanus. They include the cultivated radish, Raphanus sativus and the common wild radish or jointed charlock, R. raphanistrum. Some authors accept the podding or rattail radish, R. caudatus as a third member of the genus, while others treat it as a variety of R. sativus. Substantial numbers of other species in the genus have been proposed at various times, but almost all are currently regarded as varieties of R. sativus, while a few are treated as varieties of R. raphanistrum or are not accepted as well-described species.
