Eupatorium cuneifolium var. semiserratum (DC.) Fernald & Griscom | |
Eupatorium semiserratum, commonly called Smallflower thoroughwort, is a herbaceous perennial plant in Asteraceae native to the Southeastern states of the United States from Florida to South Carolina east to Missouri.[2] The stems grow from 40 to over 100 cm tall and are produced from short rhizomes. The inflorescences are composed of a large number of white flowers with disc florets and no ray florets. This species is similar to Eupatorium linearifolium but has smaller heads of flowers and stems which branch near the tips rather than near the base.[3] The plants previously known as Eupatorium glaucescens or Eupatorium cuneifolium are now classified as E. semiserratum or E. linearifolium.[4][5]
Another related species is Eupatorium lancifolium, which is found in Alabama, Arkansas, Louisiana, and Texas, and which has sometimes been classified as part of E. semiserratum.[6]
