Melampyrum nemorosum maakt onderdeel uit van een complexe soortengroep. Het onderscheid tussen de taxa berust voornamelijk op het beharingstype van de kelk, de lengte van de kelktanden, de bouw en kleur van de bracteeën, de lengte en vorm van de kroon. Bovendien veranderen deze eigenschappen in de loop van het groeiseizoen (
Verloove).
