A reassessment of the nomenclature of Matricaria L. and Tripleurospermum Sch Bip. (Asteraceae)

The nomenclature of the taxa often called Matricaria recutita L. (common chamomile) and Tripleurospermum perforatum (Merat) Lainz (scentless mayweed) is discussed with reference to nomenclatural history, recent typifications, and the provisions of the International Code of Botanical Nomenclature. Justification is presented for the use of the name Matricaria chamomilla L. for common chamomile and the epithet inodorm rather than perforatum for scentless mayweed, both of which have been avoided in much recent literature. Varietal nomenclature of M. chamomilla is addressed, and the combination Tripleurospermum maritimum subsp. inodorum is validated.
