Tropicals & Tender Perennials: T & M Brug or Dat?, 1 by echoes

This thread started in the Canadian forum when I asked for help starting some brug seeds. When the brug addicts found that I'd bought T & M seeds, they warned me they could be dats. http://davesgarden.com/t/416341/
I'm having an ongoing friendly chat with a nice lady from customer service at Thompson and Morgan. I can get my money back, but that's not the point. Suspect the attitude is 'Brug/Dat, pretty much the same, sorry your packet should have said Datura.'

So....anyone want to guess what these will be?

The seed pkt said Brugmansia x candida Double White Lady
Inside packet said Datura x candida Double White Lady

This sounds similar to a mix up on another thread, all stemming from the same picture on different seed packages.
