The genus Sarracenia was updated to FNA (2009) and a recent article Rice (2018) (attached). Kartesz (1994, 1999) recognized S. rubra in a very broad sense including 5 ssp.  Some of these are recognized as distinct species by FNA (2009).  Also, Rice (2018) updates Sarracenia rubra by describing the new ssp. viatorum  (Per SC Weakley is going to recognize the Rice 2018 treatment of Sarracenia rubra and ssp. viatorum in his forthcoming treatment.)
