Description Coarse vines with few branches; stems and leaves densely yellowish-villous; stems brownish, terete, striate, not fistulose. Leaves opposite; blades broadly ovate to ovate-lanceolate, to 18 cm long and 10 cm wide, the base rounded to cordate, the margins entire or with remote denticulations, the apex acute to narrowly short-acuminate, the surface densely villous with stout hairs, without glandular punctations, pairs of secondary veins prominent near the base and near the basal fourth; petioles rather stout, to 2 cm long. Inflorescence a pyramidal panicle with paniculate branches, the ultimate branches 1-4 mm long, densely hirtellous. Heads 7-9 mm high; subinvolucral bract ovate to obovate, 2.5-4.0 mm long with few to many abaxial hairs; involucral bracts broadly oblong with rounded tips, 3-5 mm long and 1 mm wide, glabrate; corolla whitish or pinkish, 4.5-5.0 mm long, the tube 2 mm long, the limb abruptly broadly campanulate, the lobes triangular, 1.0-1.5 mm long, 0.7-1.0 mm wide, with a few apical hairs; anther appendanges firm, oblong-ovate, 1? times as long as wide; style base slightly thickened, glabrous, the style appendages with only short papillae. Achenes with 5 ribs, 3-4 mm long, with a few long hairs along the costae, the base of achene
Habit vines
Description slightly attenuated; carpopodium small; pappus of ca. 35-50 slender bristles, the tips of the bristles often slightly enlarged.
Distribution widely distributed from Costa Rica to the Amazon Basin of Brazil and reaches south to Bolivia.
Note Many variations have been named as distinct species. The present broad concept follows mostly that of Steyermark (1953) with the exclusion of Al. monagasensis Badillo of Venezuela (see Aristeguieta, 1964) and M. lanuginosa DC. of southeastern Brazil, and with the inclusion of M. skutchii Blake of Costa Rica. The excluded species listed above, as well as M. eriophora Schultz-Bip. and the doubtfully distinct M. pyramidata D.Sm. both of Mexico and northern Central America, can be distinguished from M. banisteriae by the leaves being distinctly trinervate from at or very near the base of the blade. In M. banisteriae the leaves are less strongly trinervate from higher on the blade, nearer the basal fourth.
