Abstract

In this report we document the naturalization of three species of Asteraceae, Ageratina adenophora, Galinsoga quadriradiata, and Vernonia elliptica, in Taiwan. A taxonomic treatment, line drawings of all three species and of Vernonia gratiosa, an indigenous plant in Taiwan, to aid in identification, a distribution map showing the location of these introduced species in Taiwan and notes on these adventive species are provided.
