family Chenopodiaceae is now included in Amaranthaceae s.l. Phylogenetic research supports the monophyly of the subfamily. According to Kadereit et al. (2006) and Piirainen et al. (2017), it comprises just one tribe, the Salicornieae. Traditionally two tribes had been distinguished, Halopeplideae and Salicornieae, but these are not monophyletic. Tribus Salicornieae: with 12 genera and over 100 species: Allenrolfea Kuntze, with 3 species in North and South America. Arthrocaulon Piirainen & G.Kadereit (formerly part of Arthrocnemum) Arthroceras Piirainen & G.Kadereit (formerly part of Arthrocnemum) Halocnemum M.Bieb., with 2 species, from Southern Europe and North Africa to Asia. Halopeplis Bunge ex Ung.-Sternb., with 3 species, from the Mediterranean basin and North Africa to Southwest Asia and Central Asia. Halostachys C.A.Mey. ex Schrenk, with only one species: Halostachys belangeriana in Central and Southwest Asia and southeastern Europe Heterostachys Ung.-Sternb.: with 2 species in Central and South America Kalidium Moq. (Syn.: Kalidiopsis Aellen): with 6 species in Central and Southwest Asia and Southeast Europe Mangleticornia P. W. Ball, G. Kadereit and X. Cornejo, with one species: Mangleticornia ecuadorensis in Equatorial-Pacific mangroves of South America. Microcnemum Ung.-Sternb., with only one species: Microcnemum coralloides in Spain, Turkey, Armenia, and northwestern Iran Salicornia L., with over 50 species worldwide when Sarcocornia is included, especially in the Northern Hemisphere Tecticornia Hook f. (inclusive Halosarcia Paul G.Wilson, Pachycornia Hook. f., Sclerostegia Paul G.Wilson, Tegicornia Paul G.Wilson), with about 44 species, in Australia, and along tropical coasts of the Indian Ocean to eastern and western tropical Africa. Sarcocornia A.J.Scott, with about 30 species worldwide, is now sunk into Salicornia.
