The stem is red, creeping along the ground at the bottom and branching at the top, reaching a height of 15-30 cm. The leaves are alternate, obovate-elliptical, 1-2.5 cm long, rounded at the tip, wedge-shaped at the base, and short-stalked. From June to September, 3-5 small yellow flowers bloom among 4-5 bundles of leaves at the end of the branches. There are two bracts at the base, 5 perianth pieces that are obovate with a concave tip, and 7-12 stamens. The fruit is a operculum with a membranous texture, and the seeds are black and numerous. It is widely distributed in temperate and tropical regions around the world. The stems and leaves are edible.
