Eupatorium ×pinnatifidum Elliott. Lacyleaf Eupatorium. Hab: Pine flatwoods, marshes. Dist: E. VA south to Panhandle FL.

Origin/Endemic status: Endemic

Taxonomy Comments: It is variously considered a species (as by S), a species of hybrid origin (as by SE), or a hybrid (as by GW and K). The parents are variously listed as E. capillifolium × perfoliatum (as by K) or E. capillifolium or compositifolium × perfoliatum (as by GW and SE). I have seen the plant in Pender County, NC, where it appears to be a first-generation hybrid, growing with E. capillifolium and E. perfoliatum. Until and unless additional evidence appears that it reproduces itself and exists in independent populations it should be treated as a hybrid rather than a species of hybrid origin. It is recognizable by its pinnatifid or bipinnatifid leaves (the segments broader than in the dog-fennels) and its corymbose-paniculate inflorescence.
