Interpretive Summary: A tropical tree, Citronella suavoelens, that was previously only known from Malaysian Borneo, Indonesia, and Papua New Guinea, was discovered in Vietnam. It joins a list of more than 30 other plants that have been discovered in Vietnam and neighboring countries Cambodia and Laos since 2001 that have a similar pattern of distribution. These disjunct distributions presumably reflect the fact that Vietnam was connected to Sumatra and Borneo during ice ages, when sea levels were lower.

Technical Abstract: Citronella suaveolens is reported from Quang Nam Province in southern Vietnam, representing the first record of this species and the genus Citronella in the country and in mainland Southeast Asia in general. Detailed photographic illustrations of studied specimens are provided. A key to the Vietnamese genera and species of Cardiopteridaceae is presented. Diversity of Citronella in the Malesian region is discussed. Floristic affinities of Malesia and Eastern Indochina are highlighted by a list of illustrative examples.
