Mopane leaves consist of two symmetrical leaflets, which fold together during the heat of the day, to reduce evapotranspiration. Mopane growth forms range from tall homogeneous stands with trees of up to 24 meters tall on deep alluvium soils, but remains a small tree or shrub on eroded duplex soils Plant and Soil Vol. 273, pp. 203-209
