Query: Excellent resource

I saw this in someone else's home and came home and ordered it. It is a great book with beautiful photos and great descriptions. My only complaint is that I would like to see it be a bit more comprehensive. On my property alone I have so far noticed over 35 varieties of wildflowers and quite a few of them are not listed in the book. However, it did help me identify several of them, and of the books I looked through, this one seemed to be the best!
