This distinctive grape has generally prostrate stems, small rotund leaves and few tendrils. It occurs mostly on cobble-bars along or near medium-sized creeks and rivers of south-central states in the central and lower Mississippi Rv. drainage. There are also disjunct plants in Atlantic states from Va. to Pa. (K). In Ky. and Tenn. (Ch) some records need verification, and more field work is needed to document the range. Records from BELL, CALL and OWSL (KSNPC; SERNEC) remain dubious and unmapped here; the coll. by J. Conrad from OWSL (MO, NCU) may be baileyana. The species is locally common along the lower Rockcastle Rv., and it is scattered elsewhere along the lower Cumberland Rv., lower Tennessee Rv. and major tributaries. It also occurs in s. Ind. and should be expected in w. Ky. (D, K).
