Description:

Pine barrens boneset is a white-flowered, flat-topped 1m tall Eupatorium of wet places, notable for being glandular and pubescent more or less throughout (Godfrey & Wooten 1981; Cronquist 1980; Radford et al. 1968). John Torrey collected a specimen from New Jersey in 1835 and recognized it as being different from all other known species (Mowbray 1984). It is a plant with a knotty basal crown that perennates by long scaly offshoots from the crown buds (Boyer 1995). It can be considered a bimodal disjunct in that it is found in New Jersey, but formerly in Delaware and New York, and then disjunct to the sandhills and coastal plain of the Carolinas. It is a Federal Species of Concern and considered rare throughout its range.

120 element occurrences in New Jersey and North Carolina, with many populations in disturbed sites. There are 63 populations extant in NC as of January 1995. It is mainly confined to Fort Bragg and the surrounding area and some private lands in the New Jersey pine barrens (Boyer 1995)
