Treatment

Eupatorium torreyanum Short & R. Peter View in CoL ( Asteraceae ) is native to the eastern United States and was identified by Bonnie Semmling in a dry meadow in the interior of Liberty State Park ( U.S.A. New Jersey. Hudson Co.: Jersey City, Liberty State Park-Northern Interior [Communipaw], 5 Jul 2021, Schmidt et al. 666, CHRB), extending its range into northern New Jersey.

Transfer from Waif to Established Species

Diplotaxis tenuifolia (L.) DC. ( Brassicaceae ) was noted by Addison Brown as “common in all our ballast grounds” in 1879, including the area that would become Liberty State Park ( Brown 1879; U.S.A. New Jersey. Hudson Co.: Hoboken , Hoboken , 3 Jul 1880, Brown s.n., NY) . We subsequently re-collected this species in the same locality, Liberty State Park , almost 150 years later ( U.S.A. New Jersey. Hudson Co.: Jersey City , Liberty State Park-Sullivan Natural Area [ Communipaw ], 25 May 2021, Schmidt et al. 335, CHRB) . We assert that this subsequent collection is not the result of a secondary introduction but rather indicates that there is an established population at Liberty State Park. No established populations have been identified in southern New Jersey.
