Colocasia yunnanensis (Araceae), a New Record for the Flora of Vietnam

Abstract

Colocasia yunnanensis C. L. Long & X. Z. Cai (Araceae) is described as a new species record for the flora of Vietnam based on material collected from the mountainous region of Sa pa, Lao Cai Province. Characters that distinguish C. yunnanensis from other Colocasia species are noted and illustrated with photographs. Information on habitat, distribution, variability, seedling germination, and DNA variation are also provided. The possible significance of inter-species hybridization for taxonomic identification is noted.
