Interactive Key to the Ferns of the Hawaiian Islands
by Amanda Vernon and Tom Ranker

The Interactive Key to the Ferns of the Hawaiian Islands is an electronic, web-based diagnostic key designed for efficient and easy identification of Hawaiian ferns. The interactive key was created using Lucid v3.5 software. The interactive key treats all 204 currently recognized native and naturalized Hawaiian fern taxa.

Nomenclature has been updated to comply with the most recent taxonomic treatments. Nearly all taxa are accompanied with images showing the general plant form and further diagnostic characters. Diagnostic characters and character states are accompanied with images or illustrations along with definitions. A glossary and fact sheets are accessed within the key. Fact sheets include species descriptions, distributions, Hawaiian names, and synonyms.
