Taxonomy Comments: Disagreeing with Austin (1977), this taxon is evidently specifically distinct from I. carnea, based on different morphology, different habitat, and allopatric distribution. At species rank, the name with priority is I. batatilla (Kunth) G. Don, based on Convolvulus batatilla Kunth 1818 [1819], which has priority over I. fistulosa Martius ex Choisy 1845.
