Abstract
Names within Passiflora section Dysosmia (Passifloraceae) were evaluated for proper typification and nomenclatural clarity. Because several names lacked type material, 13 lectotypes, two neotypes, and four epitypes are here designated to maintain nomenclatural stability. Many more names suffered from other nomenclatural discrepancies and thus four orthographic errors, six author citations, and 12 type designations are here corrected to comply with the International Code of Nomenclature (ICN). Seven names in Dysosmia are treated as ambiguous and 12 names are identified as either invalid or illegitimate.
