Discussion:

This species superficially resembles D. sarmentosa Sw., but differs in the glabrous stems, leaves, stipules and sheaths of the stipules, obtusely angled stems, glabrous hypanthia and fruits, bifid instead of capitate stigmas, and a longer corolla in which the shorter tube is longer than the corolla lobes.
