Sonerila quangnamensis, a new species from Truong Son Mountain Range, Vietnam, is described and illustrated here. Like S. plagiocardia, S. quangnamensis has obliquely ovate leaves, which are unequal in size within each pair. However, S. quangnamensis is obviously distinct in several characters: the cross-section of its stems and petioles is terete (vs. 4-winged), the adaxial surface of its leaves is covered with hispidulous-pilose (vs. puberulous), the hypanthium is unribbed (vs. 6-ribbed), and its anthers are uniformly yellow (vs. purple to purplish-pink, yellow-tinged towards the base).
