Oxyria is a genus of flowering plants in the family Polygonaceae with three accepted species. It has a circumboreal distribution in the northern hemisphere.
==Description== Species of Oxyria are perennial herbaceous plants or weakly shrubby. They may have rhizomes. Their stems are erect, variably branched. Undivided leaves are present both at the base of the plant and on the stems. They are arranged alternately and have stalks (petioles). The ocrea is tubular and membranous. The inflorescences are terminal, paniclelike or racemelike, borne on stems (pedunculate). Individual flowers are either bisexual or unisexual, with four greenish to reddish brown tepals. The fruits are in the form of achenes with broadly winged margins.
