The title implies that it's a botanical monograph rather than a "gardener's guide," and the former would make me more likely to buy it. I was wondering in particular about the coverage of the North American species. ANy comments will be much appreciated. If it's anything like The Genus Tulipa and The Genus Epimedium, then it's most likely to be an excellent monograph with a small section on cultivation. Bob Nold Denver, Colorado, USA
