General/Distribution: A small genus with 10-12 species, distributed in the Saharo-Sindian region and Central Asia. Often separate into Londesia Fisch. & C.A.Mey. (Iljin in Komarov, l.c. 124. 1936; Tsien Cho-po & Ma Cheng-gung, l.c.) and Echinopsilon Moq. (Iljin in Komarov, l.c. 96). The genus Bassia All. as adopted by Hedge (l.c.) and here, has a close relationship with Kochia Roth, in which a winged fruiting perianth is present.
