Triaenophora is a genus of flowering plants native to Temperate Asia.

[2] Its family placement is not fully settled, as of March 2022[update]: it may be placed in Orobanchaceae or Plantaginaceae.

[1] When that family was shown by molecular phylogenetic studies not to be monophyletic, and so was split up, Triaenophora was placed in Plantaginaceae,[4] a placement still used by Plants of the World Online as of March 2022[update].

[2] Subsequent studies have shown that Triaenophora forms a clade with Rehmannia, basal to parasitic genera in the family Orobanchaceae.

[4][5] While a 2009 study left Triaenophora unplaced as to family,[4] a 2019 study placed it in a more broadly circumscribed Orobanchaceae:[5] Rehmannia-Triaenophora clade Lindenbergia clade (Lindenbergieae) remaining Orobanchaceae As of March 2022[update], Plants of the World Online accepted four species:[2]
