Apios is a genus of flowering plants in the family Fabaceae. It belongs to the subfamily Faboideae. Its member species are found in North America and Asia between latitudes of 50° and 20°.[1] The term "Apios" comes from the Greek word for "pear" and may refer the pear shape of some tubers.[1] Several members of this genus are known to have edible, tuberous roots.[1]
