Triaenophora
# Triaenophora

Triaenophora is a genus of flowering plants native to Temperate Asia. 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, 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 as of March 2022. Subsequent studies have shown that Triaenophora forms a clade with Rehmannia, basal to parasitic genera in the family Orobanchaceae. While a 2009 study left Triaenophora unplaced as to family, a 2019 study placed it in a more broadly circumscribed Orobanchaceae:

| Orobanchaceae s.l. Rehmannia-Triaenophora clade Lindenbergia clade (Lindenbergieae)  remaining Orobanchaceae | non-parasitic |
| - | - |

### Species

As of March 2022, Plants of the World Online accepted four species:

* Triaenophora bucharica B.Fedtsch.
* Triaenophora integra (H.L.Li) Ivanina
* Triaenophora rupestris (Hemsl.) Soler.
* Triaenophora shennongjiaensis Xi.D.Li, Y.Y.Zan & J.Q.Li
