Abstract

Deutzia glomeruliflora is reported from Lao Cai and Ha Giang provinces in Northern Vietnam, representing the first record of this species and the genus Deutzia in Vietnam and in the Indochinese region. Type material of this species is analyzed and lectotypification is provided; the specimen at P (P00709445) is designated as a lectotype. Patterns of distribution of Deutzia are discussed with emphasis on the floristic regions inhabited by this genus. Detailed photographic illustrations of studied specimens are provided. A key to the Vietnamese genera and species of Hydrangeaceae is presented.
