Tripleurospermum is a genus in the chamomile tribe within the sunflower family.[2][3] Mayweed is a common name for plants in this genus.[4]
Most of the species are from Europe and temperate Asia although a few are from North America and North Africa. The species are placed in Matricaria by some authors.[5][6][7]
Plants typically have lobed leaves that are composed of one to three opposite pairs cut almost to the leaf mid rib: they have indehiscent one-celled fruits that have 3-ribs and two resinous glands at the base, Matricaria species are distinguished from these species by lacking fruits with 3-ribs and the two glands.[8]
