Kozhevnikov described Stellaria depressa var. arenicola (Novosti. Sist. Vyssh. Rast. 20: 105. 1983) based on a specimen from Kaschgaria (Xinjiang). It was described as having smaller, often apetalous flowers (2–2.5 vs. 4–5 mm) and indistinct sepal veins. The present authors have seen no material of this taxon and do not know if it warrants recognition.
