'''''Matricaria perforata''''' is a species of [[Mayweed]]. The taxonomy of the genus [[Mayweed|Matricaria]] has been the subject of some controversy, with many revisions in recent years. The [[Flora Europaea]] uses ''Matricaria perforata'' for this species. Synonyms/other scientific names include ''Tripleurospermum perforatum'' (Mérat) Lainz, ''Tripleurospermum maritimum'' subsp. ''inodorum'', ''Tripleurospermum inodorum''. Common name(s): scentless mayweed, scentless chamomile, wild chamomile, mayweed, false chamomile, German chamomile, [[Baldr]]'s Brow Origin Eurasia, North Africa Considered an invasive weed in North America {{Inc| Matricaria chamomilla, Linn.
