Halostachys C.A.Mey. ex Schrenk in Bull. Cl. Phys.-Math. Acad. Pétersb. 1: 361. 1843, nom. cons. prop., sec. Kühn (1993)


This monotypic genus of Salicornieae is distributed in central, south and west Asia and southern and eastern Europe. It is closely related to Halocnemum and Halopeplis (Kadereit & al. 2006).
Nomenclatural note: Pfeiffer (1874) had chosen Halostachys songarica Schrenk as the type of Halostachys, but this species was by that time already placed in the new genus Halopeplis (see Piirainen 2015 for details). A proposal has been published to conserve the name Halostachys with H. caspica as its conserved type (Piirainen 2015).
