aminium ions

Cations HR3N+ formed by hydronation of an amine R3N . 'Non-quaternary ammonium ions' is a synonymous term, e.g. prolinium, PhN+HMe2 , N,N-dimethylanilinium.
If a class X can be hydronated to Xium ions the class Xium ions commonly includes the derivatives formed by the replacement of the added hydron with a hydrocarbyl group. Aminium ions form an exception, made possible by the availability of the class name ammonium ions.
