Though the list of nomina generica conservanda must be kept as small as possible, both the spirit of the rules and wish of all taxonomists is to aim at stabilizing nomenclature. In general the number of new combinations necessary through the digging up of an old name or the discovery of the identity of a mis-identified plant will be decisive. If the number of new combinations towards the one or the other side are nearly equal, the generic name which has been in current use will generally be favoured. If no new combinations are necessary, the current use only will be regarded as the reasonable decision.
