It is the most beautiful collection of botanical illustrations and filled with useful information. One time I realised I didn't know how a cashew grew, if it was huddled in a pod with lots of other ones or hiding inside a tough shell. I looked it up and was so surprised, who knew just how rare and strange they really are. I can't find an image of it but I highly recommend getting a copy of the book. Sesame seeds are also quite surprising.
I think all those involved deserve credit.
