The Genus Sarracenia was named after Michel Sarrazin (1659 -- 1735), who has been called the founder of Canadian science. A French naturalist and surgeon, he became acquainted with the French botanist Tournefort and sent him examples of the New World northern pitcher plant, Sarracenica purpurea , after being appointed as surgeon-major in Quebec. Sarrazin contracted ship's fever while attending patients at Hotel Dieu and died in 1735 (Anonymous 1984). The genus Sarracenia Linnaeus is in the family Sarraceniaceae, which also includes Darlingtonia Torrey and the South American genus Heliamphora Bentham. Several others and I have informally concluded that the differences between those three genera, which together comprise the entire family Sarraceniaceae, are of such a degree that Darlingtonia and Heliamphora probably should be placed in their own families. The main commonality is that all three are New World pitcher plants; however, there are significant floral and vegetative differences among the genera. There seems to be nothing subtle about pitcher plants. Their general appearance begs attention, and when we encounter them we are almost startled. But once we look for awhile, then wander among them, we can begin to peel apart layers of subtlety and see many little secrets that collectively fit these plants so neatly into their bog habitat -- and we still do not know all the secrets.
