Eriogonum spergulinum is a species of wild buckwheat known by the common name spurry buckwheat. There are three varieties: two are limited and endemic to the Sierra Nevada in California; while the more common of the three, var. reddingianum, the Redding buckwheat, can be found from California to Idaho. This buckwheat is an annual herb varying in form from prostrate to erect, 40 centimeters long including inflorescence. The plant is mostly naked, with sparse linear leaves around the base of the stem and at points along the stem. The flowering stem is slender and branching, bearing clusters of small white flowers with dark midribs.
