The following websites share information about the wonderful, wetland loving sedge family -- known around the world as Cyperaceae. The Cyber Sedge (1) site, from the Texas A&M University - Bioinformatics Working Group, contains a nice collection of Carex species illustrations "by Harry Charles Creutzburg for Kenneth Kent Mackenzie’s (1940) North American Cariceae, two volumes edited by Harold William Rickett and published by the New York Botanical Garden." The second (2) site, from the Digital Flora of Texas - Vascular Plant Image Library, links to many quality images of Cyperaceae from a number of different collections. The third (3) site, from the Kew Royal Botanic Gardens, features the three editions of their Cyperaceae Newsletter. This site also links to some brief information about sedge research at Kew. The fourth (4) site —- a Cyperaceae Species List -- is part of the National Museums and Galleries of Northern Ireland and Environment and Heritage Service - Flora of Northern Ireland website. The species are listed by scientific and common name, and each individual species links to a Northern Ireland distribution map (some species pages also include photographs and brief descriptions). The Sedge Meadow (5) website, a feature of the Killdeer Countryside Virtual Wetlands Preserve, was created by junior high school students as part of the Illinois Museums in the Classroom program. The site contains a short, concise introduction to sedge meadows, and provides links to information about various animal inhabitants such as cranes, whirligig beetles, beavers, and turtles. The final (6)
site is a Species List and Identification Key for Sedges from the USGS Northern Prairie Wildlife Research Center. Each sedge species links to a feature page with a clear close-up photo, simple U.S. distribution map, and brief information about field marks, habit, flowers, stems, and more. [NL]
