Query: A good pictoral on orchids, with 100 full pages of pictures.

This book provided a great overview of the main genus of orchids. I would have liked to have seen more about how the genus are related, and which can be crossed to produce a hybrid. Also, what techniques are used for judging orchids? The pictures themselves are worth the price of this book. More than half of the orchids pictured will be imposible to find, but a good local gardener will be able to find you a close match.
