Oh, there will always be plenty of confusion. That's a good thing, in a way, if you know what I mean.
More stuff to explore, anyway.
If you're old-fashioned like me, I would recommend the book by Miles Anderson (under various titles), which is a concise visual encyclopedia with lots of useful info, and a great starting point for exploring some of the more obscure realms. There are also two recent books by Jeff Moore with lots of pictures and info about succulents in general, or about aloes and agaves, two of my favorite members of the group. None of these books are very expensive, and a lot of the photos are inspirational.
