Bassia hyssopifolia has been reported from southern Saskatchewan, but H. J. Scoggan (1978–1979, part 3) noted that this record possibly referred to Kochia scoparia (Linnaeus) Schrader. Putative hybrids between B. hyssopifolia and K. scoparia are reported from Utah (S. L. Welsh 1984). Such hybridization is extremely interesting because it has not been reported within the native ranges of those species in Eurasia. I have seen only one specimen that might represent such a hybrid. Its general habit resembles Bassia (including pubescent leaves), but its perianth segments are very variable, with winglike, conic, or almost spinescent appendages.
