Recent taxonomic and floristic accounts list Kadsura scandens (Blume) Blume as the sole native Kadsura species in Singapore. However, these works have overlooked Ridley’s earlier documentation of another species, Kadsura verrucosa (Gagnep.) A.C.Sm., which was recorded under the misapplied name K. cauliflora. The reduction of Kadsura cauliflora to a synonym of K. scandens led to the uncritical acceptance of a single Kadsura species in Singapore. The confusion between Kadsura scandens and the morphologically similar K. verrucosa may be partly attributed to the demonstrably ambiguous lectotype of K. scandens. An epitype is therefore designated for Kadsura scandens. Key differences between the two Kadsura species and brief propagation notes are provided here.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
