Triaenophora is a genus of flowering plants native to Temperate Asia.[2] Its family placement is not fully settled, as of March 2022: it may be placed in Orobanchaceae or Plantaginaceae.
Taxonomy
The genus Triaenophora was first erected by Hans Solereder in 1909,[1] based on a section of the genus Rehmannia which Joseph Dalton Hooker had called "Trianophora" in 1891.[3] It was initially placed in the family Scrophulariaceae.[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.[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]
