Line drawings are derived from the public domain Britton & Brown (1913 [An Illustrated Flora of the Northern United States, Canada and the British Possessions]) and from: Beal (1960 [Manual of Marsh and Aquatic Vascular Plants of North Carolina]: Sagittaria), Blomquist (1957 [Brittonia]: Hexastylis), the Flora of North America Association (Amaranthus, Yevonn Wilson-Ramsey, illustrator; Carex, Susan A.

Maps are provided courtesy of the North Carolina Natural Heritage Program and USDA PLANTS. Where our taxonomy differed with USDA PLANTS, new maps were generated based on herbarium, literature, and field study. For consistency, empty USDA PLANTS base maps were populated, and both data and map sources acknowledged.
The thumbnail viewer was developed by Highslide Software (Torstein Hønsi, proprietor). Code for expanding/collapsing content was modified from the public domain code developed by Leo Charre and Jesse Fergusson (internetconnection.net). Code for the dropbox shadow was provided by Robert Nyman (robertnyman.com).
Special thanks are due to (1) Misty Buchanan (NC Natural Heritage Program), Rob Evans (NC Plant Conservation Program), Laura Gadd (NC Natural Heritage Program), Derick Poindexter (Appalachian State University), and Lesley Starke (NC Plant Conservation Program), whose expertise greatly facilitated the locating and imaging of taxa, and (2) Shawn Oakley (NC Natural Heritage Program) and Derick Poindexter (Appalachian State University) for critically reviewing the work prior to release.
