I highly suggest Eric Hansen's 'Orchid Fever', like Heather said, it has Averyonov and some other known names, and discusses corruption in CITES (that is the main jist of the entire story, and to reveal the stupidity of the laws). Cribb actually tried to sue Hansen after the book came out, because it was ruining his reputation, but I think Eric told me the case didn't hold water...
Since I know you are interested in North American orchid species, try Carl Luer's 'The Native Orchids of Florida' and 'The Native Orchids of North America Excluding Florida'... these are quite expensive and somewhat rare (because no one wants to give them up), but they contain very valuable information, as Dr. Luer photgraphed every picture (maybe excluding a few taken by his son or wife)...
I do not suggest Paul Martin Brown's books, they are up to date names, but he splits everything he can into new species... he has also used a few of Dr. Luer's photos, in which Luer told me that Brown didn't even ask for permission (even though Dr. Luer says he doesn't care, it bothers me to be seeing stolen pics on an "original" work of Brown's)... Brown also described Hexalectris spicata var. albolabia off a picture take by Dr. Luer in the 1970's of a single albino form found only in Dr. Luer's back yard... and Cliestes bifaria and Cliestes divaricata is the same species, C. bifaria being a white variety, and C. divaricata being the pink... Sacoila plaudicola are of plants found in Citrus County, and it is just a variety with tiny white dots... so I don't use P.M. Brown's books anymore...
