That's why you will rarely hear a scientist speak in absolute terms.
We certainly don't want to discourage anyone, but Lori and I can recount many times when we thought we were sure of a plant's identity, only to find with further research, re-examination, taking with other plant people, or the revelation of new data that we were wrong. It's human nature to want to be right, but no one source has all the answers (including the Utah Digital Atlas). Everything is just one reference for your consideration. People run to wikipedia, but if you consider the sources (anyone can contribute after going through the protocol) it may or may not be good at all. Likewise, our ATP database can only be as reliable as its contributors.
