mayan

Explanation:

Cempasuchil is a term from Nahuatl. Nahuatl was the language of the Aztecs. The word cempasuchil in Nahuatl means "the flower of 20 petals". Spanish has different words for marigold (like "flor de muerto" but not cempasuchil). Aztec is a culture, not a language. Mayan refers to a different Meso - american group with their own language (Yucatec Maya, etc.) which is not related to this term.
