The scientific name of the baobab is Adisonia digitata. 'Digitata' refers to the palmate stucture of the leaves - they look like fingers (or digits) on a persons hand.
Of the nine species of Adisonia, six are native to Madagascar, two are native to mainland Africa and the Arabian Peninsula, and one is native to Australia.
This particular tree is way out of its home range, which extends only as far south as the Olifants River in Limpopo, but it seems happy enough. There are a lot more baobabs to be seen at the nearby botanical gardens, but this is the most accessible one in Nelspruit.
