Kozhevnikov described Stellaria merzbacheri (Novosti. Sist. Vyssh. Rast. 20: 105. 1983) based on a specimen from the Tian Shan region of Xinjiang. It would key out closest to S. discolor based on its glabrous stems and narrowly ovoid leaves (ca. 1.4 cm × 5–6 mm). Other features of this taxon include sepals 2.5–3.5 mm, slightly shorter than the petals, with a broadly membranous margin and indistinct veins. The present authors have seen no material of this taxon.
