Ageratina dendroides is a species of flowering plants in the family Asteraceae. It is found only in Ecuador.Jørgensen, P. M. & S. León-Yánez. (eds.) 1999. Catalogue of the Vascular Plants of Ecuador. Monographs in Systematic Botany from the Missouri Botanical Garden. 75: i–viii, 1–1181. Its natural habitats are subtropical or tropical moist montane forests and subtropical or tropical high-altitude grassland. It is threatened by habitat loss.
Etymology 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.Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 39
