Type: Described from North America.

Reported from N.W.F. province from Akbarpur, B. L. Burtt 1045, 1052 (E), by R. R. Stewart, l.c. but we have not come across any specimen from our area. Seems to be a rare species. Also reported by Munshi & Javeid l.c. from Benhama (Ganderbal) and Srinagar, probably a recent introduction. Closely related to Persicaria pubescens in overall features but differs by having erect racemes and smaller nuts whereas in P. pubescens the racemes are drooping and nuts are larger; Distribution: North and South America, introduced elsewhere.
