We would appreciate your courtesy in acknowledging the National Plant Data Center and the PLANTS database when using or reproducing these data, as well as the contributions of the following specialists:

Vascular Plants

PLANTS’ vascular plant nomenclature, most phytogeography, and core attribute data for the United States and its Caribbean territories are provided under a cooperative agreement with John Kartesz and his staff at the Biota of North America Program (BONAP).

Pacific Basin vascular plant checklists, excluding Hawaii, are being developed by Warren L. Wagner, Department of Botany, Smithsonian Institution, and George Staples, The Bishop Museum, Honolulu. Longterm maintenance of the Pacific Basin checklist is being done by Dr. Wagner. All users of Pacific Basin vascular PLANTS data should acknowledge the contributions made by the Smithsonian and Bishop museums.

Nonvascular Plants

Lichens

Robert Egan (U. Nebraska at Omaha) and Theodore Esslinger (North Dakota State University) assembled the lichen checklist in PLANTS, which is based upon the North American lichen checklist published periodically in the Bryologist. Roger Rosentreter of the Bureau of Land Management provided some of our lichen common names from an unpublished manuscript.

Mosses

Marshall Crosby of the Missouri Botanical Garden is currently updating our moss checklist in association with botanists working on bryophytes for the Flora of North America. Lewis Anderson and Molly McMullen of Duke University developed the original list.

Liverworts and hornworts

Ray Stotler and Barbara Crandall-Stotler of Southern Illinois University, Carbondale developed these checklists.
