It has established its feral population in Taipei, and is closely related to the formerly introduced cultivated species A. oleracea (L.) R. K. Jansan and the indigenous species A. paniculata (Wall. ex DC.) R. K. Jansen of Taiwan. However, the three species are distinguishable by the conformations of leaves, heads and achenes. In addition to its description and distribution, a colorful photograph, a line drawing illustration and a simplified key to the three species addressed above are also provided in this article. %M doi:10.6165/tai.2007.52(3).276
