Dimidiated, (fr. mi-parti) halved; applied to animals, birds(especially eagles), fleur-de-lis, &c., of which only one half is shewn, in consequence of the field being party per pale. When only two half-charges are joined together, e.g. a rose and pomegranate, they may be blazoned as a demi-rose conjoined with a demi-pomegranate. See arms of BILSON under Pomegranate, and of CINQUE PORTS under ship.
