Chloracantha G.L.Nesom, Y.B.Suh, D.R.Morgan, S.D.Sundb. & B.B.Simpson

Kingdom: Plantae Rank: Genus Parent: Asteraceae Status: Valid

Common Names:

  • MEXICAN DEVILWEED - English, United States of America
  • SPINY-ASTER - English, United States of America


Notes: The genus is composed of a single species occuring from the sw U.S. to Central America (Nesom et al. 1991). It is distinctive, but of uncertain phylogeny, and has been placed in a variety of genera including Aster, Erigeron, and Leucosyris; based on DNA evidence, C. spinosa seems more closely related to Boltonia and Heterotheca than to either Aster or Erigeron; it is thus recognized in its own genus (Nesom et al. 1991). (Greek: chloro, green, and acanthos, spine or thorn, in reference to the evergreen thorny stems) (tribe Astereae)
