I just took a look at the USDA-AMS site, but there's really nothing there. I also did an ask.com and google search, but haven't found anything concrete yet. What I've posted came from a cousin who used to work for the USDA.
If I find anything concrete, I'll be sure to post it.

Please do. Because I grow venus's flytraps and this might be a new plant growing hobby -one with a payoff.
