Grandidier's Baobab

Some baobabs are reputed to be many thousands of years old, which is difficult to verify as the wood does not produce annual growth rings, though radiocarbon dating may be able to provide age data.
Occurrence
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.
