The scientific name on an annotation label or determination label just as a single letter followed by a specific epithet (the species name is not completely written out).
If the first letter is the same as the previous annotation, it is safe to assume the same genus is being used. For example, you would enter the scientific name of the annotation above as Dryopteris intermedia since the initial determination was Dryopteris. If the first letter is not the same, you may have to do a little research to determine what that first letter might indicate. Also make sure to check the rest of the specimen to see if there was an annotation label that you missed. When all else fails, change the processing status of the record to Expert Required and describe the problem in the Data Generalizations field.
