In some cases, individual species maps will have multiple colors regarding nativity [e.g., Chenopodium album, dark olive green (native), orange (native historic), teal (adventive), and also dark navy blue (exotic)]. This map suggests that in various U.S. states, at least one infraspecific taxon of the species complex is native, another is exotic, a third is adventive and a fourth show as rare. Once published, the Floristic Synthesis will show state-level nativity and rarity for each infraspecific taxon, however, for this website, we have provided only full species-level maps.
