Wester dock, rumex aquaticus, is found in all the western states, in moist locations from low to high elevations. Large heart-shaped leaves grow around the base, and smaller, ovate leaves along the branched stalks which hold the elongated inflorescence. Flowers are greenish pink to red around the edge, with three sepals surrounding three central scales, at the end of a short stalk, and they grow densely along the uppermost 10 to 20 inches of the stems.
