Taxonomic Comments
Varieties of Drosera rotundifolia are not recognized by Mellichamp (in FNA (2015, vol. 6)) or Brouillet et al. (accessed 2024). According to Weakley et al. (2024), "Var. comosa Fernald (of ne. US and e. Canada) does not appear to warrant taxonomic recognition (Haines 2011)." POWO (accessed 2024) includes D. rotundifolia var. gracilis as a synonym of D. rotundifolia. Kartesz (1999) recognized three North American varieties.
