Abstract
A new species, Metapetrocosmea culaochamensis, discovered in central Vietnam, is described and illustrated. This species resembles M. poilanei but differs in its inflorescence in form of compound cymes with 2 or 3 orders of branching (vs. simple cyme, with 1 order of branching), larger bracts, 10–14 × 7–8.5 mm (vs. ca. 3 × 1.5 mm), corolla tube funnelform (vs. obliquely campanulate), and the stigma with an emarginate apex (vs. entire). In addition, Paraboea myriantha, a species previously known from China, is recorded for the first time in northern Vietnam, which essentially expands the known area of this species.
