Discussion
J. K. Small (1933), B. L. Robinson (1934), R. W. Long and O. Lakela (1971), and W. C. Holmes (1981, 1993) recognized Mikania batatifolia. Hn. Alain (1962) referred M. batatifolia to M. micrantha Kunth, a common, polymorphic taxon of humid American tropics. A. Cronquist (1980) merged M. batatifolia with M. scandens. In reexamining the members of the M. scandens complex, which includes M. batatifolia (Robinson), it is apparent that M. batatifolia is distinct. Differences with M. scandens, including chemical evidence, were cited by Holmes (1981). For additional information, see Holmes (1981, 1993).
