A description of Dioscorea floridana is provided in The Flora of North America. Dioscorea floridana is a perennial herbaceous vine. The University of Florida has provided an accessible online PDF on how to differentiate the several species of yam in Florida. See link provided here: [Air Potato PDF] [1] D. floridana species is distinguished by having the two or three staminate inflorescences when compared to D. quaternata and D. villosa.[2]


According to the USDA NRCS website, Dioscorea floridana's distribution occurs in South Carolina, Georgia, and Florida. [3] Due to its limited range, it is considered vulnerable on the Global Status. [4]
