Pachythamnus is a genus of Mesoamerican flowering plants in the tribe Eupatorieae within the family Asteraceae.[2][4]
The only known species is Pachythamnus crassirameus, native to Guatemala, Nicaragua, El Salvador, and central and southern Mexico.[1]
Ageratina is derived from Greek meaning 'un-aging', in reference to the flowers keeping their color for a long time. This name was used by Dioscorides for a number of different plants.[5]
