Discussion

Historical records for Petrorhagia prolifera exist also for California (1902; Congdon s.n., MIN), Ohio (last collected in 1896; Stair s.n., OS), and South Carolina (1800s; Durand s.n., NY).

Petrorhagia prolifera has been known in the northeastern United States since at least 1837, and its range has since expanded, with isolated populations occurring southwestward from New Jersey toward Arkansas and Oklahoma as well as western Michigan. Some introductions may have been as a contaminant in grass seed used for highway planting in Tennessee (B. E. Wofford et al. 1977). Literature reports of P. prolifera in Louisiana and West Virginia have not been confirmed.
