@austinrkelly Thanks for the response - some follow-up questions:
What other resources besides iDigBio can I check? According to that site I have at least two county records and a state record which I find hard to believe.
When submitting to a herbarium, what information should be included? Pressed plant, coordinates, date, collector name, county, description of habitat… anything else?
How do I submit specimens? Mail or hand delivery or either?
