Kinkeliba and its natural habitat 

Kinkeliba usually grows in a dry and arid climate which explains why it is well adapted to the West African region. It can be found in savannah, skeletal soil, crystalline rocks, laterite, and pure dense stands. The plant is part of the Combretaceae family, very present in the group of Angiosperms (flowering plants). It is a shrub usually 4m high but can reach 10 to 20 m in favourable conditions.
