Most of the weeds! ;-) Many, but not all, species of Graminae, Cyperaceae,
Amaranthaceae, Portulaceae, Chenopodiaceae, Euphorbiaceae, Nyctoginaceae,
Aizoaceae, Compositae, and Zygophyllaceae are C-4 plants. But I cannot think
of any commonly cultivated C-4 species that you have not named, other than
perhaps amaranth (and crabgrass!).
