Derivation of the botanical name:
Tripleurospermum, Greek treis, "three," pleura or pleuron, "rib," and sperma, "seed," referring to the achenes
perforatum, with the paired leaves joined at the base and thus 'perforated' by the stem.
inodorum, in, "in, into, for, contrary;" odorus, "sweet smelling, fragrant;" unscented.
Matricaria, Latin matrix, "womb," mater, "mother," caries, "decay," because of its one-time medical use in affections of the uterus.
