Genus Metagentiana T. N. Ho & S. W. Liu (Gentianaceae Juss.) – a new record for flora of Vietnam

Ho et al. proposed to exclude Stenogyne section from the genus Gentiana and classifying it as a distinct genus (Metagentiana ). Fourteen species of this genus have been recorded and distributed in China, Myanmar and Thailand. This is the first time there has been a confirmed genus Metagentiana distributed in Vietnam. This genus has two species: Metagentiana rhodantha and Metagentiana primuliflora , which are proposed in Vietnam. Particularly, Metagentiana rhodantha , which had only been known from China, was reported in Vietnam. A detailed description along with their distribution, habitat, ecology, illustrations, and photos has been provided to aid species identification. The key to identify all taxa of the genus has been constructed
