Short description: Species of flowering plant

Eupatorium novae-angliae, commonly called New England boneset,^[1] New England justiceweed^[3] or New England thoroughwort,^[4] is a rare and endangered North American species in the family Asteraceae. It is found only in 4 counties in southern New England (Plymouth and Barnstable Counties in Massachusetts , plus Newport and Washington Counties in Rhode Island).^[2] The species is listed as endangered species in both states.^[4]

Specimens of Eupatorium novae-angliae have been collected for many years, classified by botanists as the more widespread species E. leucolepis, found from Long Island to Texas . More recent analysis of chromosomes reveals that the New England plants do not appear to be closely related to E. leucolepis. Eupatorium novae-angliae first formed as a hybrid between two other species, neither of them E. leucolepis. .^[2]^[5]^[6] It is self-sustaining, rather than being found only where both parents are present, so various authors since 1992 have proposed treating it as a distinct species.^[7] A formal renaming was published in 2005.^[1]^[8]

Eupatorium novae-angliae is a tall perennial sometimes over 3 feet (90 cm) tall. It has opposite, lance-shaped leaves, and flat-topped arrays of a large number of tiny flower heads. Each head has 5 white disc florets but no ray florets.^[2]
