Discussion

The name Chenopodium botryodes Smith was sometimes applied to C. chenopodioides because of uncertainty about the proper application and typification of the name Blitum chenopodioides Linnaeus. The recent publication by P. Uotila (2001) provides a reasonable solution by maintaining the traditional usage through neotypification of the Linnaean name.
