The baobab (Adansonia), or monkey bread tree are a genus of eight species of trees, native to Madagascar (the centre of diversity, with six species), and mainland Africa and Australia (one species in each). The mainland African species also occurs in Madagascar, but it is not a native of that country. The species reach heights of between 5–25 m (exceptionally 30 m) tall, and up to 7 m (exceptionally 11 m) in trunk diameter. They are noted for storing water inside the swollen trunk, with the capacity to store up to 120,000 litres of water to endure the harsh drought conditions particular to each region [1]. All occur in seasonally arid areas, and are deciduous, shedding their leaves during the dry season. Some are reputed to be many thousands of years old, though as the wood does not produce annual growth rings, this is impossible to verify; few botanists give any credence to these claims of extreme age.

The Malagasy species are important components of the Madagascar dry deciduous forests. Within that biome, A. madagascariensis and A. rubrostipa occur specifically in the Anjajavy Forest, sometimes growing out of the tsingy limestone itself.

Species

• Adansonia digitata – African Baobab (northeastern, central & southern Africa)
• Adansonia grandidieri – Grandidier's Baobab (Madagascar)
• Adansonia gregorii (syn. A. gibbosa) – Boab or Australian Baobab (northwest Australia)
• Adansonia madagascariensis – Madagascar Baobab (Madagascar)
• Adansonia perrieri – Perrier's Baobab (North Madagascar)
• Adansonia rubrostipa (syn. A. fony) – Fony Baobab (Madagascar)
• Adansonia suarezensis – Suarez Baobab (Diego Suarez, Madagascar)
• Adansonia za – Za Baobab (Madagascar)

The name Adansonia honours Michel Adanson, the French naturalist and explorer who described A. digitata.

The leaves are also common as a leaf vegetable throughout the area of mainland African distribution, including Malawi, Zimbabwe, and the Sahel. They are eaten both fresh and in the form of a dry powder. In Nigeria, the leaves are locally known as kuka, and are used to make kuka soup. The dry pulp of the fruit, after separation from the seeds and fibers, is eaten directly or mixed into porridge or milk. The seeds are most used as a thickener for soups, but may also be fermented into a seasoning, roasted for direct consumption, or pounded to extract vegetable oil. The tree also provides a source of fibre, dye, and fuel.

The Boab was used by Indigenous Australians as a source of water and food; the leaves were used medicinally. They also painted and carved the outside of the fruits, and wore them as ornaments. A very large, hollow boab south of Derby, Western Australia was used in the 1890s as a lockup for Aboriginal prisoners on their way to Derby for sentencing. The Boab Prison Tree still stands and is now a tourist attraction.
