A Critical Review of Published Variants of Sarracenia purpurea L.

Abstract

Reports of the nine named infraspecific variants of Sarracenia purpurea L. are critically reviewed and bibliography listed. The author concludes that at present, three of these are acceptable: ssp. purpurea, ssp. venosa and f. heterophylla. "Horticultural variety Louis Burk" (Wherry) may also be a genetic entity sufficiently discontinuous for separate designation but requires further study.
