Adansonia is a genus of eight species of tree, six native to Madagascar, one native to mainland Africa and the Arabian Peninsula and one to Australia. The mainland African species also occurs on Madagascar, but it is not a native of that island. A typical common name is baobab. A typical baobab tree stands at over 20 meters tall.

 Adansonia digitata, the baobab, is the most widespread of the Adansonia species on the African continent, found in the hot, dry savannahs of sub-Saharan Africa. It also grows, having spread secondary to cultivation, in populated areas. The northern limit of its distribution in Africa is associated with rainfall patterns; only on the Atlantic coast and in the Sudan does it's occurrence venture naturally into the Sahel. On the Atlantic coast this may be due to spreading after cultivation.
Its occurrence is very limited in Central Africa and it is found only in the very north of Southern Africa. In Eastern Africa the trees grow also in shrub lands and on the coast. In Angola and Namibia the baobabs grow in woodlands, and in coastal regions, in addition to savannahs. Also found in Dhofar region of Oman and Yemen in the Arabian Peninsula, Asia. This tree was found recently in India in the states of Andhra Pradesh (although this claim is disputed)and in Karnataka.
