The Ana tree grows in many parts of Africa and is commonly found in river beds. It has adapted to withstand waterlogging after heavy rains and also to tolerate long periods of drought by sending its roots deep underground for water. Formerly classified as a type of Acacia, the Ana tree was transferred to its own genus because its annual cycle is the opposite of the Acacia, with the Ana being bare in the summer and in leaf and flower during the winter. So this tree, photographed in springtime, will be soon be losing its leaves.
