Treatment appears in FNA Volume 21. Treatment on page 547. Mentioned on page 546.

Stems obscurely 6-angled, sometimes winged on angles, often densely glandular, glabrous or puberulent; internodes 3.5–13 cm. Petioles 10–40 mm, glabrous, glandular. Leaf-blades deltate-ovate, 1.5–6 × 1–5 cm, (subcoriaceous to somewhat fleshy) bases cordate to subcordate, margins usually hastately dentate to ± lobed (lobes divergent), apices acute to acuminate, faces glabrous (and glanddotted). Arrays of heads corymbiform, 2–4 × 2–6 cm. Heads 4–6 mm. Phyllaries lanceolate to narrowly ovate, ca. 3.5 mm, apices acuminate (abaxial faces puberulent). Corollas white, ca. 3 mm, glanddotted, lobes deltate. Cypselae brown, 1.5–2 mm, densely glanddotted; pappi of ca. 40 white, barbellate bristles ca. 3 mm.


Phenology: Flowering year round.

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).
