Discussion
Parnassia parviflora has been included in P. palustris by some authors. Small-flowered plants of P. palustris usually have the staminodes divided into about nine filaments distally and the anthers exceed 1.5 mm, but rarely some plants cannot be clearly assigned to one or other of these species. In Nunavut, P. parviflora is known only from Akimiski Island in James Bay.
