Description

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]

Distribution

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]

Ecology

Habitat

Generally, D. floridana can be found in dry to mesic forests as well as swampy forests.[5] It has been observed to occur in wet, sandy areas like pond edges, dry slopes, and woodland patches.[6] It has also been found in a coastal hydric hammock and an upland mixed forest in the Waccasassa Bay State Preserve in Levy county, Florida.[7]

Associated species: Carya glabra, C. tomentosa, Pinus palustris, Cornus florida, Collinsonia anisata, Vaccinium stamineum var. stamineum, Vaccinium sp., Quercus falcata, Quercus pumila, Morella cerifera, Rubus cuneifolius, Viburnum rufidulum, and Erianthus sp.[6]

Phenology

This species flowers from June to July as well as from August to November.[5] D. floridana has been observed flowering in March.[8]

Conservation and management

While it is not listed for any conservation population concerns, D. floridana has such a limited native range that leads it to be of conservational interest.[9]
