Notes

Comments

Kozhevnikov described Stellaria brachypetala var. magna (Novosti. Sist. Vyssh. Rast. 20: 106. 1983) based on a specimen from the Tian Shan region of Xinjiang. It was described as being more robust (stems to 25 cm), with the pedicels spreading in fruit. The present authors have seen no material of this taxon and do not know if it warrants recognition.
