In Vietnam, many newly discovered species are narrowly distributed, often restricted to a single or a few adjacent mountains. Here, we describe two new species from northern Vietnam, Begonia dinhtuana and B. caelata, both of which belong to Begonia sect. Platycentrum. Detailed morphological descriptions, illustrations, and comparisons with closely related taxa are provided to support their taxonomic recognition. DO -10.6165/tai.2026.71.55
