Adapted to the drier savannas and transitional woodlands of tropical Africa, Hannoa undulata displays distinctive wavy-margined leaflets that characterize its foliage. This hardy tree spans across the Sahelian zone from Senegal eastward to Sudan and Uganda. Local communities frequently utilize its bitter bark and light wood for various domestic and medicinal purposes.
Hannoa undulata grows as a medium-sized tree, typically reaching a height of 10 to 20 meters. It features a rounded crown and a trunk covered in thick, corky bark that provides resistance against savanna fires. The pinnate leaves consist of several pairs of leaflets with characteristic wavy or undulate margins.
Its small, yellowish-white flowers are arranged in branched terminal panicles. The fruits are ovoid drupes that ripen to a dark purple or black color, each housing a single seed.
The soft wood of this species is locally carved into domestic utensils, bowls, and light furniture. Traditional healers use decoctions of the bark, leaves, and roots to treat parasitic infections, fevers, and digestive ailments.
