原生地・分布（英語）:

説明（英語）: Genus of about 200 species of annuals, biennials, and usually tap-rooted, some-times rhizomatous perennials from a range of habitats including mountains, wasteland, cultivated ground, and streamsides in N. temperate regions. Docks have simple, variably shaped, mainly basal leaves, which occasionally have wavy margins. In summer, the tiny, star-shaped, bisexual or unisexual flowers are borne in whorls in usually erect, dense, terminal panicles or racemes. They are followed by small, triangular, brown to red-brown fruit. Some species are invasive weeds; a few are grown for their decorative foliage or as herbs. Grow in a herbaceous or mixed border. All parts of docks may cause mild stomach upset if ingested; contact with the foliage may irritate skin.
