Discussion

Sabatia angularis has been reported as weakly natu­ralized in New Mexico (K. W. Allred 1999). Historically, S. angularis has also been found introduced in Ontario, Connecticut, the District of Columbia, and Massachusetts, and can be expected elsewhere. An old report from Maine is not implausible, but no docu­mentation has been located. A report from Wisconsin likewise is also plausible, but the provenance of the specimen is doubtful.
