Matricaria inodora Linnaeus, Flora Suecica, ed. 2: 297. 1755.

"Habitat juxta agros, vias, plateas, minus frequens, quam praecedens." RCN: 6437.

Basionym of: Chrysanthemum inodorum (L.) L. (1763) .

Lectotype (Humphries in Jarvis & Turland in Taxon 47: 364. 1998): Herb. Linn. No. 1012.12 (LINN) .

Current name: Tripleurospermum maritimum (L.) W.D.J. Koch subsp. inodorum (L.) Appleq. ( Asteraceae).

Note: Rauschert (in Folia Geobot. Phytotax. 9: 249-260. 1974) argued (incorrectly) that M. inodora L. (1755) was a superfluous nomen novum for M. chamomilla L. (1753) . Applequist (in Taxon 51: 760. 2003) gives a detailed review of the nomenclature associated with this name, accepting Humphries’ typification and concluding that the correct name for the scentless mayweed is either Tripleurospermum inodorum (L.) Sch. Bip. at species rank, or T. maritimum subsp. inodorum (L.) Appleq. at subspecific rank.
