Abstract

The paper continues a series of contributions on the taxonomic diversity of Psychotria in Vietnam. Three species are revised here for the country. Of them, P. hainanensis represents a new national record, and the presence of P. tutcheri in Vietnam is confirmed for the first time by specimen investigation. For P. prainii, two new synonyms, P. rhodotricha and P. thorelii, are proposed. For each species, a morphological description is compiled and taxonomic and nomenclatural notes are given, along with geographical distribution, notes on their ecology and phenology and analytical illustrations. Lectotypes for three names in Psychotria are designated.
