The author, Bibhutibhushan, the master that he was, did a fantastic job of creating a world that he had never seen! He lived for a long time in the small town of Ghatshila, in Jharkhand, and to my knowledge (incomplete though that is), he had never gone to Africa. But so vivid was his writing that I knew what a baobab tree would look like, decades before I actually saw one.
Wikipedia says that the other common names include (among others) “upside-down tree, and monkey bread tree”. After seeing this picture, I think I know why.
