Discussion

There is a late nineteenth century record of Lysimachia maritima from Monmouth County, New Jersey. No specimens have been found to substantiate reports (http://www.natureserve.org) of the species occurring in Nunavut.

Infraspecific taxa have been proposed based on habit, leaf shape, and capsule size. Because many intermediates exist throughout the range, and extremes can be found growing together, I follow most floras in not recognizing further division.
