Inflorescences mostly terminal, sometimes also axillary, paniclelike, interrupted. Flowers heterostylous, articulation not swollen; perianth rotate; tepals 5, connate less than 1/5 their length; stamens 8; styles deciduous, 3, included, spreading.
Discussion
Species 2 (1 in the flora).
The status of sect. Rubrivena has been controversial; its members have been included in six different genera. Herbarium specimens often are identified as Polygonum polystachyum or Aconogonon polystachyum. Hong S. P. (1993) cited morphological and anatomical evidence for including Rubrivena in Persicaria as sister to sect. Cephalophilon, also noting pollen and inflorescence characters that distinguish it from Aconogonon.
