Abstract
The names Dracontium polyphyllum L. and D. asperum K. Koch have confus ed aroid taxonomists for more than two centuries, because they pertain to similar material from the same country (Surinam), and their typifi cation is problematic. The previously designated lectotype of D. polyp hyllum is ambiguous and cannot be identified to species level; an epit ype is here designated. A neotype is designated for D. asperum. The co ncepts of the two species are elaborated.
