Tripleurospermum is a genus in the Anthemideae within the Asteraceae.[Schultz, Carl Heinrich Ġinus. 1844. Ueber die Tanaceteen: mit besonderer Berücksichtigung der deutschen Arten 31–34][ Tropicos, Tripleurospermum Sch. Bip.] Mayweed is a common name for plants in this genus.
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.[ Flora of North America Vol. 19, 20 and 21 Page 548, Tripleurospermum Schultz-Bipontinus, Tanaceteen. 31. 1844. ][ Flora of China Vol. 20-21 Page 769 三肋果属 san lei guo shu Tripleurospermum Schultz Bipontinus, Tanaceteen. 31. 1844. ][ Altervista Flora Italilana, Camomilla senza odore, Tripleurospermum inodorum (L.) Sch. Bip. includes photos and distribution maps]
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.
