Geoffroea decorticans, the chañar, kumbaru, or Chilean palo verde (green wood), is a small deciduous tree, up to 8 meters (25 ft) tall that inhabits most arid forests (montes or espinales) of southern South America. The chañar is cold and drought deciduous; it loses its leaves in winter, and possibly in summer if conditions get too dry. It is natural to Chile and Argentina, also present in Paraguay and southern Peru. It is a very characteristic tree in local culture and folk because of its vivid visual presence, propagation, and ancient ethnomedical uses.
