Comments: This tree was identified years ago as S. nudum, which is now considered to be a distinct species restricted to South America. S. aphyodendron is abundant in areas of early succession. The torn leaves produce a strong, acrid odor. As in other species of Solanum, the flowers do not produce nectar and offer pollen as the only reward to visitors, which tends to elliminate almost everything but bees. The bees hold the anthers in their mandibles and vibrate them using their wing muscles to make the pollen issue out of the tiny pores at the anther's tip. Bats remove the fruits so consistently that ripe fruits are seldom seen.
