I wrote a paper on residues on 2 million year old stone tools a few years
ago (we thought the residues might be tubers) and read up a lot on African
tubers. There are a few of them. I'll try and locate the paper and send it
to you (or at least extract the relevant bits). There is a very good book
on African wild food plants but I can't remember the name. However, I think
there is a reference to it in the paper. I'll get back to you
