Notes

A monotypic genus distributed in Afghanistan, Pakistan, India, and China (Qaiser 2001). The taxonomy of Rubrivena is complex; its members have been included in Polygonum (P. polystachyum; Li & al. 2003) and Persicaria (P. wallichii; Freeman 2005) and both names are accepted by Tropicos (undated). However, based on molecular studies, the placement of Rubrivena is strongly supported as sister to Aconogonon and Koenigia (Sanchez & al. 2011).
