|discussion=<p>Fagopyrum tataricum is homostylous and self-pollinating. Cultivated plants appear to be most closely related to the wild ones in southwestern Sichuan, China. Tartary buckwheat is a less important crop plant and is encountered less frequently in the flora area than is F. esculentum. It is cultivated in mountainous areas of Asia and elsewhere (C. G. Campbell 1997).</p>
