burkii, honoring Louis Burk as Wherry had suggested 60 years earlier. In 1999, however, botanists Robert Naczi, then a professor of biology at Northern Kentucky University, and Frederick and Roberta Case elevated the variety to species rank, naming it Sarracenia rosea. They compiled morphological data from specimens of S. purpurea and S. rosea and found significant differences in scape height, petal size, pitcher "lip" thickness, and pitcher leaf morphology.
