Abstract


Based on re-collections at known sites, field observations, researches on specimens and literatures, taxonomic revisions of seven Euonymus species from East and South Asia are provided. Three easily-confused Euonymus species from E. actinocarpus s. l. are clarified. Euonymus quinquecornutus, E. stenophyllus, and E. cornutoidesare reduced to the synonym of E. cornutus, E. clivicola, and E. frigidus respectively. E. elegantissimus is re-instated. The lectotypes are also designated for thirteen names involved within this report since the holotype were not designated in the protologue. Additionally, the conservation status of these species is also reevaluated according to IUCN standards (version 3.1). Besides the above, the key to the species in sect. Uniloculares is also provided.
