. When that family was shown by molecular phylogenetic studies not to be monophyletic, and so was split up, ''Triaenophora'' was placed in

, a placement still used by Plants of the World Online . Subsequent studies have shown that ''Triaenophora'' forms a clade with ''Rehmannia'', basal to parasitic genera in the family

. While a 2009 study left ''Triaenophora'' unplaced as to family, a 2019 study placed it in a more broadly circumscribed Orobanchaceae:
