Primulina elegans (Gesneriaceae), a new species from Vietnam is described. This species is similar to P. gemella and P. diffusa in having stolons and papillose‐hispid leaves, but is easily distinguished from them by having 9–15 cymes and corollas with two brown stripes on the adaxial lip and nine purplish lines on the abaxial lip. Furthermore, Primulina elegans differs from P. gemmella by its broadly infundibuliform corollas with purplish glandular pubescent filaments, and from P. diffusa by having three slightly purplish glandular pubescent staminodes.
