Query: A very good quick reference.

Lacking any pretence at being scientific literature this CD is no less useful. It is a compilation of linked HTML pages so a web browser is useful to view it. This makes cross references and name lookup relatively fast. The photos are perhaps its strongest asset. If you see a name somewhere you can usually look it up, see if the name is current or a pseudonym and see a very high quality photo. This is particularly helpful if you have only passing familiarity with a genus or species.The only drawback to this CD is the lack of a taxonomic key for identifying items. Since it would seem that a computer is uniquely suited to assist in the taxonomic identification of these unique plants this is unfortunate. I would strongly encourage the author to consider this addition in subsequent releases. This would make the CD truly invaluable
