Is the book Paphiopedilum good?

[naoki]

Which book are you talking about? Guido Braem & Guy Chiron? If so, I do like it (for taxonomy). I don't have Cribb's 'Genus Paphiopedilum', but I intend to get it eventually.

If you are interested in culture than taxonomy, then it is probably better to go with Birk's 'The Paphiopedilum Grower's Manual, 2nd ed.' To me, Koopowitz's book is not worth it (since I'm not interested in artificial hybrids). Slipper Orchids of Vietnam by Averyanov contains the most interesting biology of each species. It doesn't cover all species, but this is my favorite paph book. Amazon has it at the lowest-ever price at this moment ($49.95 new).
