I was so happy to get a copy of this book, much cheaper when sourced from the UK, and arrived in pristine condition...that didn't last long, my fingerprints are already on most of the pages
It's one of the "key" books on the succulent Euphorbias, and one of the few sources on the East African (Kenyan/Tanzanian/Mozambiquan) species, as you might guess from the name
But it also has lots of info about South African species, as well as pan-African species.
Cheers,
