This is a GREAT book for those interested in Christmas and Thanksgiving cacti. It has fantastic pictures, and while the authors give a great deal of scientific information, they also take care to give the conditions needed to be successful in growing these jungle cacti in the home or greenhouse.
The best parts of this book are the listings of known species and their descriptions, and the known hybrid cultivars in both the U.S. and Australia. Listing includes parentage if known.
This is one of the best, if not THE best, books on Christmas Cacti I have ever seen.
