Diodia teres is a species of flowering plant in the coffee family known by the common name poorjoe. This annual plant is found throughout the southern half of North America as well as much of the northeastern United States. It has a thin, erect stem rarely approaching half a meter in height. It has oppositely arranged leaves which are stiff, dark green, pointed, and roughly-textured. Each pair of leaves cradles a flower at its base. The small white to pink flower has four stiff petal-like lobes. The fruit is a pair of hairy nutlets. This plant is most common in sandy areas such as desert dunes and river floodplains.
