At the same time that the mineral was approved	voting on the proposed name was suspended because of an imminent report on the nomenclature of the amphibole group. Subsequently	Hogarth et al. (1987) published definitive data for the mineral without noting that it had been approved by IMA	describing it as potassium fluor-magnesio-arfvedsonite. As a result of later enquiries	and in light of the currently accepted amphibole nomenclature	Hogarth (2006) published a note in which the mineral approval was reported and named it fluoro-potassic-magnesio-arfvedsonite. This is the correct name for the mineral	renamed with IMA approval.
