Correctness of species' names from online vendors?

[ElliotLi]

I'm looking for some high quality species for my collection, mostly Phalaenopsis and Cymbidium. Since I'm also trying to hybrid them, I want their names to be as correct as possible. I don't have much time to run around the country and visit shows or expos so I prefer online vendors. What I don't know is how accurate those online vendors label their species? It would be great if you know some great nurseries that have a good reputation for high quality species (Phal or Cym) and good labeling? I browsed the vendor feedback forum, but seems few people talk about the correctness of the names of the orchids they got.

Thanks in advance!
