It is a rhizomatous perennial herb producing a prostrate, creeping, branching stem up to about 20 centimeters long, sometimes forming mats. The oval leaves are up to about a centimeter long and are borne in opposite pairs on the stem. Solitary flowers occur in the leaf axils, each borne on a short pedicel. The small flower has no petals, just four to five blunt-tipped green sepals each a few millimeters long.
