Geoffroea decorticans
''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.
==Morphology==
The common name Chilean Palo Verde comes from the mottled green color of the trunks but does not seriously resemble ''Cercidium''. The chañar tends to be quite upright with a spreading canopy with both straight and mildly curving trunks. As trees mature the trunks and branches take on a sculptural quality with long longitudinal, irregular ridges and valleys. Along with this undulating trunk, large flakes of the bark peel off or decorticate (hence the species name ''decorticans''). The peeling tan to brown bark is eventually shed revealing the dark green, "immature" trunk beneath. The contrasting colors and textures created by this puzzle-piece pattern make the tree visually fascinating.〔(''G. decorticans'' ). Arid Zone Trees〕
The flowers are very visible, small, papery and yellow-coloured. The tree flowers in spring, either singly or in clusters. ''Geoffroea decorticans'' is unique among legumes in that it produces fleshy, oval pods that hold a single seed. Fruit are initially green but turn deep orange as they mature.
