Impatiens pallida B. S. Walters

Forests (especially swampy), streamsides, ditches; much less common than I. capensis and perhaps tending toward more mesic habitats, although the two may grow together. Very local north of the middle of the Lower Peninsula, and only near Lake Michigan.

An old record from Isle Royale (University Party, 1868, MICH) has never been corroborated. It is far out of range and is not mapped as it lacks an original label and there may be a labeling mix-up. 

The recent record from Luce Co., in a new powerline (MacKinnon 2163, MICH), is suspected of having been introduced with construction equipment. 

The spur is less strongly bent than in I. capensis, sometimes nearly 180° but sometimes only about 90° from the axis of the saccate sepal.
