Section: Phemeranthus.

Origin/Endemic status: Endemic

Taxonomy Comments: P. mengesii and P. parviflorus Nuttall of the midwestern United States (and disjunct as far east as AL) are apparently the parents of the more eastern allotetraploid P. teretifolius. Diploid and tetraploid populations are known of this taxon; further investigation is needed to determine if the tetraploids are allotetraploids or autotetraploids.
