From Flora of Indiana (1940) by Charles C. Deam
I have found this species only in Tipton County in Indian Prairie in moist soil along the railroad about a half mile west of Goldsmith. Chas. M. Ek has found it in several places along railroads in Howard County. This rare form [of Rosa arkansana = R. suffulata var.relicta)] has been found in Indiana only in Tipton County in the Indian Prairie area along the railroad a short distance west of Goldsmith. "It resembles a weak R. suffulta; it is semi-herbaceous, the two year old wood being often semi-procumbent. It differs from R. suffulta in the narrow stipules, small fruit with reflexed and semi-deciduous sepals, in which characteristics it resembles R. carolina L." "R. relicta begins to flower earlier than R. suffulta, just after R. blanda and continues to flower through the summer." Like the next species [Rosa rudiuscula], it may have originated by natural hybridization.
