The genus
Triaenophora was first erected by
Hans Solereder in 1909, based on a section of the genus
Rehmannia which
Joseph Dalton Hooker had called "
Trianophora" in 1891. It was initially placed in the family
Scrophulariaceae. When that family was shown by molecular phylogenetic studies not to be
monophyletic, and so was split up,
Triaenophora was placed in
Plantaginaceae, 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
Orobanchaceae. }} The placement in the tribe Rehmannieae of the family Orobanchaceae was accepted by the
Angiosperm Phylogeny Website, .
