Plants of Hawai'i: Useful Websites

Plant databases and checklists maintained by the Bishop Museum, including taxonomic names, native and naturalized Hawaiian vascular plants and algae, a kalo identification guide, and a Hawaiian ethnobotany database.

This joint project of the Smithsonian Institute and the National Tropical Botanical Garden provides information on Hawaiian vascular plants taken primarily from The Manual of the Flowering Plants of Hawai`i by Wagner, Herbst, and Sohmer (1999) and Hawai`i's Ferns and Fern Allies by Palmer (2003).
