North America, Eurasia, North Africa, some species widespread weeds in the southern hemisphere.
Species 7 (3 in the flora).
Matricaria has been confused with Tripleurospermum (see discussion under the latter). Typification of Matricaria was discussed by K. Bremer and C. J. Humphries (1993), who rejected the arguments of S. Rauschert (1974) in favor of the use of Chamomilla over Matricaria.
