Discussion

The recently discovered populations of Prosartes trachycarpa in Isle Royale National Park, Michigan (E. J. Judziewicz et al. 1997), are noteworthy disjunctions for this otherwise western species.

This rare old-forest obligate is readily distinguished by its purple-spotted, clawed tepals and its three-lobed, straw-colored, hairy-papillose fruit (R. G. Johnson 1968).
