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).
