아직 국표식이나 국생지에 등록되지 않은 종이다. 몇 년 전에 고대 모 교수님이 학명과 국명을 알려주었다고 인터넷에 나온다. 아직 그 교수님이 발표하지 않은듯하다

Eupatorium altissimum occurs in sexual diploid populations in the Ozark region of Missouri and Arkansas, and as apomictic polyploids elsewhere throughout its range. It occurs almost exclusively on limestone soils, where it is often accompanied by (and sometimes misidentified as) Brickellia eupatorioides, which has 10-ribbed cypselae and plumose pappus bristles. Eupatorium altissimum hybridizes with E. serotinum
