A herb. It grows 10-30 cm tall. It grows from seed each year. The stems are thick and rounded. They are pale green and fleshy. The leaves have stalks. These are 1-2 cm long. The leaf blades are 0.8-3.5 cm long by 0.6-2.8 cm wide. They are oval and shiny pale green. The base is heart shaped. The flowers are yellow. They are very small and borne on a light green spike. This is produced at the end of a branch or opposite the leaves. The nutlet is round and 0.5 mm across.
