|discussion=<p><i>Drosera tracyi</i> occurs on the Gulf Coastal Plain from southwestern Georgia to southeastern Louisiana. The species has been reported from South Carolina; no specimens from there have been seen. The leaves and flowers are larger than those of <i>D. filiformis</i>. An anthocyanin-free form with white flowers is known.</p><!--
--><p>B. A. Sorrie (1998b) gave evidence from morphology and ecology that <i>Drosera tracyi</i> is distinct from <i>D. filiformis</i>. <i>Drosera filiformis</i> has been found growing with <i>D. tracyi</i> in Bay and Washington counties, Florida, without apparent hybrids (Sorrie). This seems to be a natural disjunction, but <i>D. filiformis</i> has been planted outside its range. An artificial hybrid, which is sterile, between these two species has resulted in a cultivar named ‘California Sunset.’</p><!--
--><p>Many artificial hybrids have been made and given formal or informal cultivar names. The following sterile wild hybrids have been reported.</p><!--
--><p><i>Drosera</i> ×beleziana Camus (<i>D. intermedia</i> × <i>D. rotundifolia</i>): Nova Scotia, Michigan.</p><!--
--><p><i>Drosera</i> ×hybrida Macfarlane (<i>D. filiformis</i> × <i>D. intermedia</i>): New Jersey.</p><!--
--><p><i>Drosera</i> ×linglica Kusakabe ex Gauthier & Gervais (<i>D. linearis</i> × <i>D. anglica</i>): Quebec.</p><!--
--><p><i>Drosera</i> ×obovata Mertens & Koch (<i>D. anglica</i> × <i>D. rotundifolia</i>): British Columbia, southeastern Canada, Newfoundland, Quebec, Great Lakes region, northern California, Oregon, Washington, and New England.</p><!--
--><p><i>Drosera</i> ×woodii Gauthier & Gervais (<i>D. linearis</i> × <i>D. rotundifolia</i>): Quebec.</p><!--
--><p><i>Drosera capillaris</i> × <i>D. intermedia</i>, no hybrid name given: Pender County, North Carolina.</p>
