(updated 11 February 2011)

Below is a working checklist of Mount Desert Island's hornworts. This list and nomenclature is based on a very old (1924) article in Rhodora, the journal of the New England Botanical Club. Therefore, there is likely much updating of the taxonomy necessary.

Please send corrections and updates to Photographs are welcome. Thank you.
