We are getting strange results from the Auto generated plant codes. Instead of the expected results of codes made up of the first three letters of the genus and the first three letters of the species we are getting some codes consisting of the first three letters of the genus and the next three letters appear to be random excerpts from portions of the common name. Other times the species portion of the code has a number 2 at the end even though the standard letter code has not been used. Are these expected results?
