This species is treated here in a broad sense. The Salicornia europaea aggregate is represented in Eurasia and North America by several diploid and tetraploid races. Most probably Chinese plants belong mostly (or exclusively) to the Eurasian continental race known as S. prostrata Pallas (Ill. Pl. 8. 1803). The taxonomy of this group in China is in need of revision.
