Alph.Wood}} is widely used today.{{r|NatureServe|POWO:280472-1|FNA:250094595}}{{sfnp|Weakley|Southeastern Flora Team|2022}}{{sfnp|Haines|2011}}{{sfnp|Gilman|2015}}

''Cardamine maxima'' is a member of the ''Cardamine concatenata'' alliance, a monophyletic group of eastern North American species that includes ''Cardamine angustata'', ''Cardamine concatenata'', ''Cardamine diphylla'', ''Cardamine dissecta'', ''Cardamine incisa'', and ''Cardamine maxima''.{{r|Sweeney and Price 2001}} All members of the alliance were previously placed in genus ''Dentaria'' {{small|Tourn. ex L.}}, which is now considered to be a synonym for ''Cardamine'' {{small|L.}}{{r|POWO:30001912-2}}
