Summary Zhu, G. & Grayum, M. H.: Two hitherto confused species, Dracontium polyphyllum and D. asperum (Araceae) , and typification of their names. – Taxon 44: 519‐523. 1995. – ISSN 0040‐0262. The names Dracontium polyphyllum L. and D. asperum K. Koch have confused aroid taxonomists for more than two centuries, because they pertain to similar material from the same country (Surinam), and their typification is problematic. The previously designated lectotype of D. polyphyllum is ambiguous and cannot be identified to species level; an epitype is here designated. A neotype is designated for D. asperum. The concepts of the two species are elaborated.
